L-glutamine is an essential amino acid that is a crucial component of culture media that serves as a major energy source for cells in culture. L-glutamine is very stable as a dry powder and as a frozen solution. In liquid media or stock solutions, however, L-glutamine degrades relatively rapidly.…

Poly-lysine is a polycation which binds to DNA, red cell membrane and any negatively charged protein. It is typically used as a coating substrate for culture dishes, slides, etc. It enhances electrostatic interaction between negatively charged ions of the cell membrane and the culture surface. When…

Leucine is a branched-chain α-amino acid. Leucine is classified as a hydrophobic amino acid due to its aliphatic isobutyl side chain. Leucine has been used as a molecular marker in the recovery of DNA from palaeontological samples for PCR analysis.

The essential amino acid L-histidine is one of the three amino acids with a basic side chain, and is very hydrophilic in character. It contains an imidazole group in the side chain. L-Histidine has been used to study cultures of the human T-lymphoblastic leukemia cell line MOLT-4 to study…

L-Glutamine, the uncharged and amidated analog of L-glutamic acid, is an important amino acid for the incorporation of NH4+ into biomolecules. It is biosynthesized from NH4+ and glutamate via the enzyme glutamate synthetase. In turn, degradation of glutamine to free the ammonia moiety is mediated…
