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.
- Ribonucleosides
- Deoxyribonucleosides

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
- Ribonucleosides
- Deoxyribonucleosides

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:
- Potassium Chloride
- Potassium Phosphate, monobasic
- Sodium Bicarbonate
- Sodium Chloride
- 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.
