    Advanced-MEM-Alpha with Nucleosides in Earle’s Buffer

    Background

    PurMaTM Advanced-MEM-Alpha with Nucleosides (A-MEM-α-N) in Earle’s Buffer contains components that allow for a 60–90% reduction in FBS supplementation. More importantly, using synthetic components such as recombinant insulin, albumin, and transferrin increases consistency. This results in less variation amongst lot-to-lot serum changes. In A-MEM-α-N, L-Alanyl-L-Glutamine is used as the source of glutamine. Additionally, reducing FBS requirements lowers the cost of cell culture experiments.

    Contents

    Advanced MEM-α-N in EBSS Contains:

    • includes all twenty essential and non-essential amino acids with higher concentrations than regular and MAX formulations.
    • A-MEM-α-N incorporates elements that significantly reduce the need for a serum for cell culture.

    Crucial Ingredients:

    • PurMaTM Human Transferrin (Holo): prevents Improper iron storage and delivery in cell culture systems which is a major contributor to oxidative stress and protein damage.
    • PurMaTM Insulin Recombinant
    • Trace of other elements which mimic the elements in fetal bovine serum.
    PurMa™ Advanced MEM-α with nucleoside (A-MEM-α-N) is modified from Advanced MEM-α with the following ingredients:
    • Ribonucleosides
    • Deoxyribonucleosides
    Consequently, Advanced-MEM-Alpha with Nucleosides (A-MEM-α-N) in Earle’s Buffer is a significant step toward a chemically defined form of this media. Unquestionably, Chemically Defined Advanced MEM-α-N (CD-A-MEM-α-N) is the outcome of decades of cutting-edge research and will soon be offered globally to laboratories that are looking for consistency and repeatability in their data.

    MEM Alpha with Nucleosides in Earle’s Buffer (MEM-α-N-EBSS)

    Background

    MEM Alpha with Nucleosides in Earle’s Buffer (MEM-α-N-EBSS) is a suitable nutrient for mammalian cell culture as well as selection for transfected DHFR-negative cells. This media contains nucleoside, and the formulation is available below. depending on cell types, laboratories use MEM-α-N for growing mammalian cell for a variety of suspension as well as adherent cells. Eliminating calcium in this media facilitates the growth of cells in suspension cultures.

    Ingredients

    MEM Alpha Modification with Nucleosides in Earle’s Buffer (MEM-α-N-EBSS) is a modification of MEM.

    MEM-α-N-EBSS contains:

    • Non-essential amino acids.
    • Sodium pyruvate.
    • Lipoic acid.
    • Vitamin B12.
    • Biotin and,
    • Ascorbic acid.

    PurMa™ MEM-α-N-EBSS includes Earles’ Buffer

    As the composition of Earls buffer, it contains:
    1. Calcium chloride
    2. Magnesium sulfate
    3. Potassium chloride
    4. Sodium bicarbonate
    5. Sodium chloride
    6. Sodium Phosphate, monobasic

    PurMa™ MEM -α-N-EBSS media also contains:

    • Low level of glucose (1.00 g/ liter)
    • Sodium bicarbonate (2.2 g/L) (if higher than 5% CO2 is used, a higher % of sodium bicarbonate is needed.
    • 2 mM L-glutamine (292 mg/L)’
    • PurMa Biologics manufactures 121 types of MEM -α-N-E

    The nucleoside modifies this media  from MEM-α

    Why PurMa Biologics? Why we stand behind our cell culture media

    Our products are the outcome of 30 years of experience in cutting edge science. We routinely manufacture over 1500 media. We have the most comprehensive collection of cell and tissue culture media. Moreover, We utilize %99 pure amino acids. This will significantly increase the consistency among your experiments. Considering the highest quality, our prices certainly are extremely reasonable.

    Application

    This media can also be used for keratinocytes, primary rat astrocytes, as well as human melanoma cells. MEM-α-N-EBSS has also been used for the isolation of mesenchymal stem cells, adipose-derived stem cells, and osteoblast. Additionally, PurMa™ MEM -α-N-EBSS facilitates the growth and maintenance of primary osteoblast cultures. furthermore, this media performs well for isolation of polymorphonuclear leukocytes (PMN) from umbilical cord blood.

    MEM α-Modification with Nucleosides MAX in Earle’s Buffer (MEM-α-N-MAX-EBBS)

    Background

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

    Advantages

    The advantages of MEM-α-N-MAX over MEM-α-N 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.
    • Consequently, it 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 that prevents the degradation of L-glutamine.

    MEM α-Modification with Nucleosides MAX in Earle’s Buffer (MEM-α-N-MAX-EBBS) 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-N-MAX (EBBS) based on the amount of Sodium Bicarbonate and HEPES (PH capacity)
    • Phenol Red
    PurMa™ MEM-α with nucleosides MAX (MEM-α-N-MAX) is modified from MEM-α-MAX with the following ingredients:
    • Ribonucleosides
    • Deoxyribonucleosides
    MEM-α-N-MAX (EBBS) contains no proteins, lipids, or growth factors. Therefore, it requires supplementation, commonly with 10% Fetal bovine Serum (FBS).

MEM Alpha with Nucleosides in Earle’s Buffer (MEM-α-N-EBSS)

Background

MEM Alpha with Nucleosides in Earle’s Buffer (MEM-α-N-EBSS) is a suitable nutrient for mammalian cell culture as well as selection for transfected DHFR-negative cells. This media contains nucleoside, and the formulation is available below. depending on cell types, laboratories use MEM-α-N for growing mammalian cell for a variety of suspension as well as adherent cells. Eliminating calcium in this media facilitates the growth of cells in suspension cultures.

Ingredients

MEM Alpha Modification with Nucleosides in Earle’s Buffer (MEM-α-N-EBSS) is a modification of MEM.

Moreover, MEM-α-N-EBSS contains:

  • Non-essential amino acids.
  • Sodium pyruvate.
  • Lipoic acid.
  • Vitamin B12.
  • Biotin and,
  • Ascorbic acid.

Because PurMa™ MEM-α-N-EBSS includes Earles’ Buffer,  it contains:

  1. Calcium chloride
  2. Magnesium sulfate
  3. Potassium chloride
  4. Sodium bicarbonate
  5. Sodium chloride
  6. Sodium Phosphate, monobasic

PurMa™ MEM -α-N-EBSS media also contains:

  • Low level of glucose (1.00 g/ liter)
  • Sodium bicarbonate (2.2 g/L) (if higher than 5% CO2 is used, a higher % of sodium bicarbonate is needed.
  • 2 mM L-glutamine (292 mg/L)’
  • PurMa Biologics manufactures 121 types of MEM -α-N-E

The nucleoside modifies this media  from MEM-α

it contains:

  • Ribonucleosides
  • Deoxyribonucleosides

 

Application

Moreover, this media can also be used for keratinocytes, primary rat astrocytes, as well as human melanoma cells. MEM-α-N-EBSS has also been used for the isolation of mesenchymal stem cells, adipose-derived stem cells, and osteoblasts. Additionally, PurMa™ MEM -α-N-EBSS facilitates the growth and maintenance of primary osteoblast cultures. furthermore, this media performs well for the isolation of polymorphonuclear leukocytes (PMN) from umbilical cord blood.
