Human KLK11  (Kallikrein 11) ELISA Kit (HUFI03772)

Quantify Kallikrein 11 (KLK11), a secreted trypsin-like serine protease of the tissue kallikrein family clustered at chromosome 19q13.3-13.4, with this colorimetric microplate immunoassay from Assay Genie. KLK11, also known as hippostasin or PRSS20, has been investigated in the context of prostate and ovarian cancer progression, seminal plasma liquefaction, and the proteolytic cascade of skin desquamation, supporting its value as a quantitative analyte for oncology biomarker discovery, reproductive biology studies, and dermatology research.

Each kit contains a pre-coated microplate, biotinylated detection antibody, streptavidin-HRP conjugate, wash buffer, chromogenic substrate solution, and a lyophilized recombinant KLK11 standard sufficient for a complete standard curve. Reagents are supplied refrigerated; reconstituted standards are typically aliquoted and frozen at -20°C for repeated use, and the chromogenic substrate should be protected from light. The protocol is intended for research use only and fits within a standard biochemistry laboratory workflow that is completed within several hours.
