Human Cystatin 3 (CST3) ELISA Kit

Quantify human cystatin C, a 13 kDa cysteine protease inhibitor routinely studied as an early marker of glomerular filtration, with this 96-assay colorimetric ELISA from Assay Genie. The kit targets cystatin 3 (CST3) and supports research into renal function decline, cardiovascular risk, and neurodegenerative conditions where this inhibitor has been investigated. In addition to serum-based studies, the assay accommodates tissue homogenates, cell lysates, and cell culture supernatants, allowing researchers to examine CST3 expression in vitro across multiple experimental models. The colorimetric endpoint is read on a standard microplate reader, streamlining integration into existing laboratory workflows. Each kit is configured for research use only, providing a practical option for laboratories studying kidney physiology, systemic inflammation, or biomarker discovery in human samples.
