H-L-Photo-lysine hydrochloride 是一种含有重氮基的赖氨酸氨基酸，也是一种光交联剂。H-L-Photo-lysine hydrochloride 可以选择性的插入到蛋白质中，并用于在体外和活细胞中交联蛋白质-蛋白质相互作用。H-L-Photo-lysine hydrochloride 用作紫外光激活的光交联探针。
H-L-Photo-lysine hydrochloride is a diazirine-containing lysine amino acid and is a photo-cross-linker. H-L-Photo-lysine hydrochloride can site-selective incorporated into proteins and is used to crosslink protein-protein interactions in vitro and in living cells. H-L-Photo-lysine hydrochloride acts as a UV light-activated photo-crosslinking probe[1][2][3].
Photo-lysine, which is readily incorporated into proteins by native mammalian translation machinery, can be used to capture and identify proteins that recognize lysine post-translational modifications (PTMs), including 'readers' and 'erasers' of histone modifications[2].
