Bovine Caltrin (PYY2) ELISA Kit

Caltrin is a calcium-transport inhibitor protein originally characterized in bovine seminal vesicle secretions, where it modulates calcium influx into spermatozoa and influences sperm capacitation. This ELISA kit from Assay Genie enables quantitative measurement of caltrin in liquid specimens collected from cattle, supporting research into bovine fertility, spermatogenesis, semen quality, and male reproductive physiology. The kit is intended for research use only.

Built around a microplate format with colorimetric readout, the assay supports routine batch processing of experimental samples in academic and veterinary research laboratories. Each kit contains reagents for 96 determinations, with components supplied to generate a standard curve and to quantify endogenous caltrin/PYY2 immunoreactivity in matrices collected from cattle.

Typical workflows involve calibrator dilution on the plate, addition of samples alongside biotinylated detection antibody, incubation, washing, streptavidin-HRP addition, and final chromogenic development. Absorbance values are read and interpolated against the standard curve to derive caltrin concentrations. Storage and handling instructions supplied with the kit should be observed for reagent stability throughout the workflow.
