Human CABS1 (Calcium-binding and spermatid-specific protein 1) ELISA KIT (HUFI05393)

This immunoassay from Assay Genie enables quantitative measurement of CABS1 (Calcium-binding and spermatid-specific protein 1), a testis-enriched calcium-binding protein implicated in spermatid elongation, manchette formation, and flagellar assembly during post-meiotic male germ cell maturation. The assay uses a human-specific capture antibody pre-coated onto a microplate, paired with a biotinylated detection antibody and streptavidin-HRP conjugate, producing a chromogenic signal proportional to analyte concentration. The kit is supplied as a complete reagent set including a pre-coated microplate, lyophilized recombinant protein standards, detection antibody concentrate, streptavidin-HRP, wash buffer concentrate, chromogenic substrate, stop solution, sealed plate seals, and a detailed protocol booklet. Recommended sample volume is 100 µL per well for blood-derived specimens. Store unopened components refrigerated at 4 °C and protect the substrate from light; reconstituted standards should be aliquoted and stored frozen at -20 °C, with limited freeze-thaw cycles recommended to preserve activity.
