用途 |
一种二肽,用于哺乳动物细胞培养基中的谷氨酰胺替代物;谷氨酰胺在溶液中不稳定,形成的氨在细胞培养中具有有害效应;Ala-Glu对热消毒具有稳定性,形成氨的效果比谷氨酰胺小。作为培养基组分之一,有利于发挥其优势

用途 |
在哺乳动物细胞培养基中可以作谷氨酸盐的替代物,加热灭菌过程中稳定。
L-Glutamine is an essential supplement for cell culture. The free amino acid L-glutamine is unstable and degrades to pyroglutamate. Alanyl-L-glutamine (Ala-Gln) and Gylcyl-L-glutamine (Gly-Gln) are used in cell culture as alternative delivery forms of stabilized L-glutamine. The primary advantage of using L-alanylglutamine in place of L-glutamine is that it reduces the level of ammonia generated during cell culture
