Human Cathepsin L PharmaGenie ELISA Kit (SBRS0356)

The Cathepsin L immunoassay from Assay Genie provides quantitative measurement of human cathepsin L, a lysosomal cysteine protease implicated in tumor invasion, extracellular matrix remodeling, bone resorption, and antigen presentation pathways. Investigators studying oncology, osteoporosis, and cardiovascular biology use this kit to track cathepsin L levels in cell culture supernatant, plasma, and serum matrices.

Built around the PharmaGenie research-use platform, the kit ships as a complete 96-assay package with pre-coated microplate, biotinylated detection antibody, recombinant standards, streptavidin-HRP conjugate, and TMB substrate. The HRP-driven substrate reaction generates absorbance readings proportional to analyte concentration in each well, allowing interpolation against the supplied standard curve.

For best results, store the kit refrigerated upon arrival and equilibrate reagents to room temperature before beginning the protocol. The microplate layout supports parallel processing of standards, controls, and unknowns in a single experimental run, and the reagents are intended for research use only.
