  • L-Alanyl-L-Glutamine, 200 mM Solution in 0.85% NaCl. (ATCC® 30-2115)

    ATCC® Number: 30-2115
    Quantity: 100 mL
    Storage: Store L-alanyl-L-glutamine solution at 2°C to 30°C.
    Applications:

    L-glutamine (200 mM solution in 0.85% NaCl) is an essential amino acid required by virtually all mammalian and insect cells grown in culture. L-alanyl-L-glutamine can be used as a direct substitute for L-glutamine at equimolar concentrations (2 to 4 mM for most applications). Whereas L-glutamine is labile in cell culture medium and its degradation results in a deleterious build-up of ammonia, the L-alanyl-L-glutamine dipeptide is very stable with minimal ammonia production. Once inside the cell, the dipeptide is split by aminopeptidases into L-alanine and L-glutamine.

  • ITS Solution (Insulin, Transferrin, Selenious Acid) (ATCC® 30-2606)

    ATCC® Number: 30-2606
    Quantity: 10 mL
    Storage: Store medium at 2°C to 8°C. Do not freeze.
    Applications:

    Insulin, Transferrin and Selenious Acid (ITS) have been demonstrated to improve performance in serum-free media. Insulin promotes the uptake of glucose and amino acids. Transferrin is an iron-transport protein, and with selenious acid, supplies essential trace elements normally provided by serum. ITS Solution is free of animal origin.

    Supplied at a 100x concentration. For use, aseptically add 5 mL of ITS solution per 500 mL of medium.

  • L-Glutamine Solution, 200 mM (ATCC® 30-2214)

    ATCC® Number: 30-2214
    Quantity: 100 mL
    Storage: Store L-glutamine solution frozen at -20°C or colder. Avoid repeated freeze-thaws by dispensing and storing in aliquots.
    Applications: L-Glutamine is an essential amino acid required by virtually all mammalian and insect cells grown in culture.

    L-Glutamine is also more labile in cell culture solutions than other amino acids. The rate and extent of L-glutamine degradation are related to storage temperatures, age of the product, and pH.

    All cell culture media are formulated to contain appropriate amounts of L-glutamine to support cell growth well beyond the expiration date of the media. However, if L-glutamine is suspected to be a limiting factor during cell culture, a simple test of 'spiking' the medium with a small amount of L-glutamine will determine whether or not more is required. Simply add a small amount of L-glutamine (~ 2 mM final concentration) to the culture medium. If the cell growth rate increases, L-glutamine is most likely deficient and more should be added.

    Note: L-glutamine degradation results in the build-up of ammonia which can have a deleterious effect on some cell lines. Use caution when adding more L-glutamine than called for in the original medium formulation (2 to 4 mM is standard). For most cell lines, ammonia toxicity is more critical for cell viability than L-glutamine limitation.
