    Basal Medium Eagle-MAX (BME-MAX) in Earle’s Buffer

    Background

    Basal Medium Eagle-MAX (BME-MAX) in Earle’s Buffer is a commonly used media for Mammalian cell culture.

    Advantages

    The advantages of BME-MAX over BME are:

    • Higher PH Capacity
    • Moreover, it contains 4 mM L-Alanyl-L-Glutamine (0.869 g/L) instead of L-Glutamine and therefore:
    • Possess longer shelf life.
    • More importantly, minimizes toxic ammonia build-up.
    • Significantly improves cell viability and growth.
    • Remains stable across a wide range of temperatures.
    • Improves the culture of primary cells.

    Mechanism

    Although L-glutamine is a vital amino acid, it degrades, generating toxic ammonia and pyrrolidine carboxylic acid. One way to minimize L-glutamine degradation in media is to gradually add these amino acids to your cell culture. However, keeping track of time to keep the amount of L-glutamine at the same level is tedious, if not impossible. Alternatively, L-alanyl-L-glutamine can be used because it is much more stable in aqueous solutions. More importantly, it does not easily degrade and gradually releases aminopeptidases. As a result, L-glutamine and L-alanine are then used by the cells for protein production in the TCA cycle. In addition to our Max formulation products, we manufacture PurMaTM GluaSup (Cat# P3S210 559) is a combination of L-alanyl-L-glutamine that prevents degradation of L-glutamine.

    Contents

    Basal Medium Eagle-MAX (BME-MAX) in Earle’s Buffer contains:

    • 5 mM sodium pyruvate
    • High glucose (4.5g/L)
    • Non-Essential Amino Acids
    • 3.7 g/L Sodium Bicarbonate; PurMa Biologics Manufactures several types of BME-MAX in EBBS based on the amount of Sodium Bicarbonate and HEPES (PH capacity)
    • Phenol Red
    BME-MAX in EBBS contains no proteins, lipids, or growth factors. Therefore, it requires supplementation, commonly with 10% Fetal bovine Serum (FBS).

    Background:

    Dulbecco′s Modified Eagle′s Medium-MAX (DMEM-MAX) is a commonly used media for Mammalian cell culture.

    Advantages:

    Dulbecco′s Modified Eagle′s Medium-MAX (DMEM-MAX) over DMEM:

    Higher PH Capacity Moreover, it contains 4 mM L-Alanyl-L-Glutamine (0.869 g/L) instead of L-Glutamine and therefore: Possess longer shelf life. More importantly, minimizes toxic ammonia build-up. Significantly improves cell viability and growth. Remains stable across a wide range of temperatures. Improves the culture of primary cells.

    Mechanism:

    Although L-glutamine is a vital amino acid, it degrades, resulting in the generation of toxic ammonia and pyrrolidine carboxylic acid. One way to minimize L-glutamine degradation in media is to gradually add these amino acids to your cell culture. However, keeping track of time to keep the amount of L-glutamine at the same level is tedious, if not impossible. Alternatively, L-alanyl-L-glutamine can be used because it is much more stable in aqueous solutions. More importantly, it does not easily degrade and gradually releases aminopeptidases. As a result, L-glutamine and L-alanine are then used by the cells for protein production in the TCA cycle. In addition to our Max formulation products, we manufacture PurMaTM GluaSup (Cat# P3S210 559) is a combination of L-alanyl-L-glutamine which prevents degradation of L-glutamine.

    Iscove’s Modified Dulbecco’s Medium MAX (IMDM-MAX)

    Background

    Iscove’s Modified Dulbecco’s Medium MAX (IMDM-MAX) is a commonly used media for Mammalian cell culture.

    Advantages

    The advantages of IMDM-MAX over IMDM are:

    • Higher PH Capacity
    • Moreover, it contains 4 mM L-Alanyl-L-Glutamine (0.869 g/L) instead of L-Glutamine and therefore:
    • Possess longer shelf life.
    • More importantly, minimizes toxic ammonia build-up.
    • Significantly improves cell viability and growth.
    • Remains stable across a wide range of temperatures.
    • Improves the culture of primary cells.

    Mechanism

    Although L-glutamine is a vital amino acid, it degrades, resulting in the generation of toxic ammonia and pyrrolidine carboxylic acid. One way to minimize L-glutamine degradation in media is to gradually add these amino acids to your cell culture. However, keeping track of time to keep the amount of L-glutamine at the same level is tedious, if not impossible. Alternatively, L-alanyl-L-glutamine can be used because it is much more stable in aqueous solutions. More importantly, it does not easily degrade and gradually releases aminopeptidases. As a result, L-glutamine and L-alanine are then used by the cells for protein production in the TCA cycle. In addition to our Max formulation products, we manufacture PurMaTM GluaSup (Cat# P3S210 559) is a combination of L-alanyl-L-glutamine which prevents degradation of L-glutamine.

    Contents

    Iscove’s Modified Dulbecco’s Medium MAX (IMDM-MAX) contains:

    • 5 mM sodium pyruvate
    • High glucose (4.5g/L)
    • Non-Essential Amino Acids
    • 3.7 g/L Sodium Bicarbonate; PurMa Biologics Manufactures several types of IMDM-MAX based on the amount of Sodium Bicarbonate and HEPES (PH capacity)
    • Phenol Red
    IMDM-MAX contains no proteins, lipids, or growth factors. Therefore, it requires supplementation, commonly with 10% Fetal bovine Serum (FBS).

    Leibovitz’s L-15 Medium - MAX

    Background

    Leibovitz’s L-15 Medium - MAX is one of the commonly used Media for Mammalian cell culture.

    Advantages

    The advantages of Leibovitz’s L-15 MAX over Leibovitz’s L-15 are:

    • Higher PH Capacity
    • Moreover, it contains 4 mM L-Alanyl-L-Glutamine (0.869 g/L) instead of L-Glutamine and therefore:
    • Possess longer shelf life.
    • More importantly, minimizes toxic ammonia build-up.
    • Significantly improves cell viability and growth.
    • Remains stable across a wide range of temperatures.
    • Improves the culture of primary cells.

    Mechanism

    Although L-glutamine is a vital amino acid, it degrades, generating toxic ammonia and pyrrolidine carboxylic acid. Therefore, one way to minimize L-glutamine degradation in media is to gradually add these amino acids to your cell culture.  Unfortunately, maintaining a consistent level of L-glutamine by tracking time can be a tedious and potentially impossible task. Alternatively, L-alanyl-L-glutamine can be used since it is much more stable in aqueous solutions. More importantly, it does not easily degrade and gradually releases aminopeptidases. As a result, L-glutamine and L-alanine are used by the cells for protein production in the TCA cycle. In addition to our Max formulation products, we manufacture PurMaTM GluaSup (Cat# P3S210 559) is a combination of L-alanyl-L-glutamine that prevents the degradation of L-glutamine.

    MEM Alpha-Modification MAX (MEM-α-MAX) in Hanks’ Buffer

    Background

    MEM Alpha-Modification MAX (MEM-α-MAX) in Hanks’ Buffer is a commonly used media for Mammalian cell culture.

    Advantages

    MEM-α performs better than MEM for a number of cell lines, please see the description of regular MEM-α : MEM-α

    The advantages of MEM-α-MAX in HBBS over MEM-α are:

    • Higher PH Capacity
    • Moreover, it contains 4 mM L-Alanyl-L-Glutamine (0.869 g/L) instead of L-Glutamine and therefore:
    • Possess longer shelf life.
    • More importantly, minimizes toxic ammonia build-up.
    • Significantly improves cell viability and growth.
    • Remains stable across a wide range of temperatures.
    • Improves the culture of primary cells.

    Mechanism

    Although L-glutamine is a vital amino acid, it degrades, generating toxic ammonia and pyrrolidine carboxylic acid. One way to minimize L-glutamine degradation in media is to gradually add these amino acids to your cell culture. However, keeping track of time to keep the amount of L-glutamine at the same level is tedious, if not impossible. Alternatively, L-alanyl-L-glutamine can be used because it is much more stable in aqueous solutions. More importantly, it does not easily degrade and gradually releases aminopeptidases. As a result, L-glutamine and L-alanine are then used by the cells for protein production in the TCA cycle. In addition to our Max formulation products, we manufacture PurMaTM GluaSup (Cat# P3S210 559) is a combination of L-alanyl-L-glutamine that prevents the degradation of L-glutamine.

    MEM Alpha-Modification MAX (MEM-α-MAX) in Hanks’ Buffer contains:

    • 5 mM sodium pyruvate
    • High glucose (4.5g/L)
    • Non-Essential Amino Acids
    • 3.7 g/L Sodium Bicarbonate; PurMa Biologics Manufactures several types of MEM-α-MAX based on the amount of Sodium Bicarbonate and HEPES (PH capacity)
    • Phenol Red
    MEM-α-MAX in HBBS contains no proteins, lipids, or growth factors. Therefore, it requires supplementation, commonly with 10% Fetal bovine Serum (FBS).

    MEM Alpha-Modification MAX (MEM-α-MAX) in Earle’s Buffer

    Background

    MEM Alpha-Modification MAX (MEM-α-MAX) in Earle’s Buffer is a commonly used media for Mammalian cell culture.

    Advantages

    MEM-α performs better than MEM for a number of cell lines, please see the description of regular MEM-α: MEM-a in Earle's Buffer

    The advantages of MEM-α-MAX in EBBS over MEM-α are:

    • Higher PH Capacity
    • Moreover, it contains 4 mM L-Alanyl-L-Glutamine (0.869 g/L) instead of L-Glutamine and therefore:
    • Possess longer shelf life.
    • More importantly, minimizes toxic ammonia build-up.
    • Significantly improves cell viability and growth.
    • Remains stable across a wide range of temperatures.
    • Improves the culture of primary cells.

    Mechanism

    Although L-glutamine is a vital amino acid, it degrades, generating toxic ammonia and pyrrolidine carboxylic acid. One way to minimize L-glutamine degradation in media is to gradually add these amino acids to your cell culture. However, keeping track of time to keep the amount of L-glutamine at the same level is tedious, if not impossible. Alternatively, L-alanyl-L-glutamine can be used because it is much more stable in aqueous solutions. More importantly, it does not easily degrade and gradually releases aminopeptidases. As a result, L-glutamine and L-alanine are then used by the cells for protein production in the TCA cycle. In addition to our Max formulation products, we manufacture PurMaTM GluaSup (Cat# P3S210 559) is a combination of L-alanyl-L-glutamine that prevents the degradation of L-glutamine.

    Contents

    MEM Alpha-Modification MAX (MEM-α-MAX) in Earle’s Buffer contains:

    • 5 mM sodium pyruvate
    • High glucose (4.5g/L)
    • Non-Essential Amino Acids
    • 3.7 g/L Sodium Bicarbonate; PurMa Biologics Manufactures several types of MEM-α-MAX based on the amount of Sodium Bicarbonate and HEPES (PH capacity)
    • Phenol Red
    MEM-α-MAX in EBBS contains no proteins, lipids, or growth factors. Therefore, it requires supplementation, commonly with 10% Fetal bovine Serum (FBS).
