Advanced MEM-Alpha with Nucleosides in Earle’s Buffer
Advanced-MEM-Alpha with Nucleosides in Earle’s Buffer (A-MEM-a-N-EBSS) contains L-Alanyl-L-Glutamine as well as ingredients to allow for serum reduction. More importantly, Advanced MEM-α-N needs only 2-5% FBS and provides more consistency.
Description
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.
