Description

L-Homocysteine, an amino acid, is a homocysteine that has L configuration. Homocysteine is an essential intermediate in normal mammalian metabolism of methionine. L-Homocysteine induces upregulation of Cathepsin V that mediates vascular endothelial inflammation in hyperhomocysteinaemia[1][2].

In Vitro

L-Homocysteine (0.5, 1, 2 mM; 24 h) increases the mRNA and protein levels of Cathepsin V in a dose‐dependent manner[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
