Human Cystatin 4 (CST4) ELISA Kit

An in vitro quantitative immunoassay from Assay Genie, the Cystatin 4 (CST4) ELISA Kit measures Cystatin S concentrations in human research samples. Cystatin 4, also referred to as CST4 or Cystatin S, is a member of the cysteine protease inhibitor family studied in oral health research, inflammatory disease investigations, and biomarker discovery workflows.

Each kit includes a pre-coated microplate, ready-to-use standards, a detection antibody, and substrate solution. The format supports 96 individual assays with a small sample volume required per well. Compatible sample matrices span a variety of human specimens, including tissue homogenates, cell lysates, cell culture supernatant, serum-containing biofluids, and plasma-containing biofluids.

Stored refrigerated prior to use and intended for research use only, the kit ships with complete protocol documentation, plate sealers, and a certificate of analysis. Researchers in cell biology, oral biology, and clinical biomarker studies commonly use this kit for protein quantification in their workflow.
