General description

HAVCR1 is a trans-membrane glycoprotein that is highly expressed in kidney proximal tubular cells with kidney injury. The KIM-1 ectodomain is cleaved, released into urine, and canbe quantified as a sensitive and specific biomarker for Acute Kidney Injury (AKI) in rodents and humans. In a recent study it was demonstrated that HAVCR1 is released into the circulation where it reports kidney injury in mice, rats, and humans with AKI and chronic kidney disease (CKD). Urinary HAVCR1 and MCP-1 levels, either alone or in combination, were significantly higher than those in AKI negative patients. Importantly, the combination of HAVCR1 and MCP-1 outperformed either biomarker alone.



Biochem/physiol Actions

SILuProt HAVCR1 is a recombinant, stable isotope-labeled human HAVCR1 which incorporates [13C6, 15N4]-Arginine and [13C6, 15N2]-Lysine. Expressed in human 293 cells, it is designed to be used as an internal standard for bioanalysis of HAVCR1 in mass-spectrometry. SILu Prot HAVCR1 is a protein consisting of 290 amino acids (the extracellular domain: Ser21-Gly290, and including C-terminal polyhistidine and FLAG® tags), with a calculated molecular mass of 31 kDa.

Physical form

Supplied as a lyophilized powder containing phosphate buffered saline.
