Human Sperm protamine P1 (PRM1) ELISA Kit

Assay Genie provides a high-quality Sandwich ELISA Kit for the quantitative measurement of human sperm protamine P1 (PRM1), a key sperm nuclear protein involved in DNA packaging and chromatin condensation during the haploid phase of spermatogenesis. The kit is reactive with human samples and is intended for research use only.

Validated for serum, plasma, tissue homogenates, cell culture supernates and other biological fluids, the assay offers a detection range of 1.56-100 IU/mL and a sensitivity of 0.098 IU/mL, with an intra-assay CV of 4.1% and inter-assay CV of 7.3%. Specificity has been confirmed for both natural and recombinant human sperm protamine P1.

Linearity has been verified in serum, EDTA plasma and heparin plasma across dilution ratios from 1:2 to 1:16. Recovery averages 88% for serum (range 82-94%) and 90% for plasma (range 84-96%), supporting dependable performance for studies of male reproductive health, sperm quality and infertility.
