L-histidine has been used for the selection of transformed cells. It has also been used to study its effects on the formation of verteporfin cross-linked oligomers in cellular homogenates.

For R&D use onlynot for drug household or other uses.

Histidine (abbreviated as His or H encoded by the codons CAU and CAC) is an -amino acid that is used in the biosynthesis of proteins. It contains an -amino group (which is in the protonated NH3 form under biological conditions) a carboxylic acid group (which is in the deprotonated COO form under biological conditions) and a side chain imidazole classifying it as a positively charged amino acid at physiological pH. Initially thought essential only for infants longer-term studies have shown it is essential for adults also.
