Porcine Proinsulin (PI) ELISA Kit

Quantitative measurement of porcine proinsulin, the biosynthetic precursor of insulin, is supported by this competitive immunoassay from Assay Genie. Circulating proinsulin serves as an established marker of pancreatic beta-cell stress and is widely used in metabolic disease research, islet xenotransplantation studies, and veterinary endocrinology investigations.

Built on a competitive inhibition format with a colorimetric readout, the kit is compatible with diverse sample matrices including tissue homogenates, cell lysates, cell culture supernatants, and serum or plasma preparations. This flexibility supports both in vivo animal studies and in vitro cell-based experimental workflows.

Swine models are central to diabetes research, beta-cell biology, and surgical or pharmacological intervention studies, where proinsulin-to-insulin ratios provide insight into secretory capacity. The 96-assay format enables medium-throughput screening of experimental cohorts, and the assay is intended for research use only.

Reagents should be refrigerated on arrival and equilibrated to room temperature before use. Refer to the enclosed protocol for assay preparation, washing, and standard curve generation on a standard microplate reader.
