Human Polyserase-2 (PRSS36) ELISA Kit

The deduced 855-amino acid protein has a predicted molecular mass of 93 kD and contains 9 potential N-glycosylation sites. PRSS36 contains a signal peptide, followed by a propeptide domain, an active serine protease domain with the catalytic his, asp, and ser residues, and 2 serine protease domains predicted to be catalytically inactive. The first serine protease domain shares amino acid identity of 40 to 42% with gamma-1 tryptase (TPSG1), pancreasin, matriptase (ST14; ), matriptase-2 (TMPRSS6), and polyserase-1 (TMPRSS9) . Northern blot analysis detected a 5-kb transcript in fetal kidney and adult skeletal muscle, liver, placenta, and heart. A 2.2-kb transcript was detected in placenta, prostate, and colon and lung adenocarcinoma cell lines, and may be produced by alternative splicing.

Human Polyserase-2 (PRSS36) ELISA Kit has high sensitivity and excellent specificity for detection of Human PRSS36. No significant cross-reactivity or interference between Human PRSS36 and analogues was observed.

This Human Polyserase-2 (PRSS36) ELISA Kit employs a two-site sandwich ELISA to quantitate PRSS36 in samples. An antibody specific for PRSS36 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyPRSS36 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for PRSS36 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 PRSS36 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.
