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].

IC50 & Target[1][2]

Human Endogenous Metabolite

 

cathepsin L

 

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].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Western Blot Analysis[2]

Cell Line: HUVECs
Concentration: 0.5, 1, 2 mM
Incubation Time: 24 h
Result: Increased the mRNA and protein levels of Cathepsin V in a dose‐dependent manner.
In Vivo

Note:
Please do not refer to only one article to determine the experimental conditions. It is recommended to determine the optimal experimental conditions (animal strain, age, dosage, frequency and cycle, detection time and indicators, etc.) through preliminary experiments before the formal experiment.

L-Homocysteine can be used in animal modeling to construct a model of vascular endothelial inflammation.

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.
