Human Protamine-3 (PRM3) ELISA Kit

Prm3 encoding a distinctive small acidic protein is present in 13 species from seven orders of mammals. Prm3 gene has not generated retroposons, which supports the contention that genes that are expressed in meiotic and haploid spermatogenic cells do not generate retroposons. The Prm3 mRNA is first detected in early round spermatids, while the PRM3 protein is first detected in late spermatids. Thus, translation of the Prm3 mRNA is developmentally delayed similar to the Prm1, Prm2, and Tnp2 mRNAs. In contrast to PRM1, PRM2, and TNP2, PRM3 is an acidic protein that is localized in the cytoplasm of elongated spermatids and transfected NIH-3T3 cells. To elucidate the function of PRM3, the Prm3 gene was disrupted by homologous recombination.

Human Protamine-3 (PRM3) ELISA Kit has high sensitivity and excellent specificity for detection of Human PRM3. No significant cross-reactivity or interference between Human PRM3 and analogues was observed.

This Human Protamine-3 (PRM3) ELISA Kit employs a two-site sandwich ELISA to quantitate PRM3 in samples. An antibody specific for PRM3 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyPRM3 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for PRM3 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of PRM3 bound in the initial step. The color development is stopped and the intensity of the color is measured.

• Do not mix components from different kit lots or use reagents beyond the kit expiration date.• Allow all reagents to warm to room temperature for at least 30 minutes before opening.• Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination.• Unused wells must be kept desiccated at 4 °C in the sealed bag provided.• Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.• It is recommended that all samples and standards be assayed in duplicate or triplicate.
