    Advanced MEM-Alpha with Nucleosides in Hanks’ Buffer (A-MEM-α-N-HBSS)

    Background

    PurMaTM Advanced MEM-Alpha with Nucleosides in Hanks’ Buffer (A-MEM-α-N-HBSS) contains Nucleosides as well as components that allow for a 60–90% reduction in FBS supplementation. More importantly, using synthetic components such as recombinant insulin, albumin, and transferrin increase 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 HBSS 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.
    PurMaTM Advanced MEM-α with nucleoside (A-MEM-α-N) is modified from Advanced MEM-α with the following ingredients:
    • Ribonucleosides
    • Deoxyribonucleosides
    Consequently, Advanced MEM-α with Nucleosides in Hanks’ Buffer (A-MEM-α-N-HBSS) 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 α-Modification with Nucleosides in Hanks’ Buffer

    Background

    MEM α-Modification with Nucleosides  in Hanks’ buffer provides a great nutritional culture environment during mammalian cells.  This media, as well plays a key role in the process of selection of transfected DHFR-negative cells. Moreover, MEM-α-N-HBSS is widely used for a variety of suspension and adherent cells. Calcium, however, plays a crucial role in media as eliminating this ion facilitates the growth of cells in suspension cultures.

    Ingredients

    MEM-α with nucleosides is basically the modified version of MEM-α and contains:
    • Ribonucleosides
    • Deoxyribonucleosides
    • Non-essential amino acids.
    • Sodium pyruvate.
    • Lipoic acid.
    • Vitamin B12.
    • Biotin and,
    • Ascorbic acid.

    PurMa™ MEM-α-N-HBSS contains HBSS buffer

    The composition of HBSS buffer:
    1. Potassium Chloride
    2. Potassium Phosphate, monobasic
    3. Sodium Bicarbonate
    4. Sodium Chloride
    5. Sodium Phosphate, dibasic
    Additionally, MEM-α-N-HBSS also Contains:
    • Low level of glucose (1.00 g/ liter)
    • Sodium bicarbonate (0.35 g/L)
    • 2 mM L-glutamine (292 mg/L)
    PurMa Biologics manufactures 119 types of MEM-α-N-HBSS

    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

    Furthermore,  MEM-α-N-HBSS is used for various cell types such as keratinocytes, primary rat astrocytes, as well as human melanoma cells. also, MEM-α-N-HBSS has been used for the isolation of mesenchymal stem cells, adipose-derived stem cells, and osteoblasts. Moreover, MEM α-Modification is widely used for primary osteoblast cultures.

    MEM α-Modification with Nucleosides MAX in Hanks’ Buffer (MEM-α-N-MAX-HBSS)

    Background

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

    Advantages

    The advantages of MEM-α-N-MAX (HBSS) over MEM-α-N (HBSS) 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 which prevents degradation of L-glutamine.

    Contents

    MEM α-Modification with Nucleosides MAX in Hanks’ Buffer (MEM-α-N-MAX-HBSS) 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 (HBSS) 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 (HBSS) contains no proteins, lipids, or growth factors. Therefore, it requires supplementation, commonly with 10% Fetal bovine Serum (FBS).

MEM α-Modification with Nucleosides in Hanks’ Buffer

Background

MEM α-Modification with Nucleosides  in Hanks’ buffer provides a great nutritional culture environment during mammalian cells.  This media, as well plays a key role in the process of selection of transfected DHFR-negative cells. Moreover, MEM-α-N-HBSS is widely used for a variety of suspension and adherent cells. Calcium, however, plays a crucial role in media as eliminating this ion facilitates the growth of cells in suspension cultures.

Ingredients

MEM-α with nucleosides is basically the modified version of MEM-α and contains:

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

PurMa™ MEM-α-N-HBSS contains HBSS buffer

The composition of HBSS buffer:

  1. Potassium Chloride
  2. Potassium Phosphate, monobasic
  3. Sodium Bicarbonate
  4. Sodium Chloride
  5. Sodium Phosphate, dibasic

Additionally, MEM-α-N-HBSS also Contains:

  • Low level of glucose (1.00 g/ liter)
  • Sodium bicarbonate (0.35 g/L)
  • 2 mM L-glutamine (292 mg/L)

PurMa Biologics manufactures 119 types of MEM-α-N-HBSS

Application

Furthermore,  MEM-α-N-HBSS is used for various cell types such as keratinocytes, primary rat astrocytes, as well as human melanoma cells. also, MEM-α-N-HBSS has been used for the isolation of mesenchymal stem cells, adipose-derived stem cells, and osteoblasts. Moreover, MEM α-Modification is widely used for primary osteoblast cultures.
