Description
Background
MEM Essential & Non-Essential Amino Acids Solution (50X) is indeed playing a substantial role in cell culture. Basically, Essential amino acids cannot be synthesized In Vivo, thus it is extremely important to supplement the media with those to maintain proper cellular growth and expected viability. On the other hand, mammalian cells can synthesize non-essential amino acids (NEAA) through glutaminolysis, glycolysis, or via TCA cycle.
During low concentration of required amino acids in media, cells need to consume more glucose and glutamine, which results in an unexpected amount of biodegradation products, this , indeed acts as a hindrance in proper cellular growth and maintenance. So, adding supplements of amino acids to media reduces biosynthetic burden on cell in vitro, stimulates growth and prolongs the viability of cells.

Frequently asked questions
What concentration is MEM Essential & Non-Essential Amino Acids Solution (50X) supplied at?
Most supplements and solutions are supplied as concentrated stocks, commonly 100X, for dilution into complete medium. The exact concentration is on the Certificate of Analysis for the lot.
How should it be stored?
Follow the storage line on the Certificate of Analysis, and aliquot anything supplied frozen so you are not repeatedly freezing and thawing the stock.
Is it sterility and endotoxin tested?
Yes. Each lot is tested and a Certificate of Analysis is issued and available on request for any catalogue number.
Can I get this in a custom concentration or pack size?
Yes. Custom concentrations, formulations and bulk pack sizes are made to order. Use the request bulk pricing button on this page and state the specification you need.
What is the shelf life?
Stated per lot on the Certificate of Analysis. Once opened the practical limit is usually contamination rather than chemical stability, so handle in a hood and decant rather than pipetting repeatedly from the stock.
