other gene names :
SERPINB5; SERPINB5; PI5; maspin; PI5; PI-5
uniprot entry name :
SPB5_HUMAN
specificity :
This assay has high sensitivity and excellent specificity for detection of MSB5. No significant cross-reactivity or interference between MSB5 and analogues was observed. NOTE: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between MSB5 and all the analogues, therefore, cross reaction may still exist in some cases.
storage stability :
Store all reagents at 2-8 degree C.
other info1 :
Samples: Serum, plasma, Cell Culture Supernatants, body fluid and tissue homogenate. Assay Type: Competitive. Sensitivity: 1.0 ng/mL.
other info2 :
Intended Uses: This MSB5 ELISA kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Human MSB5. This ELISA kit for research use only, not for therapeutic or diagnostic applications!
products description :
Principle of the assay: MSB5 ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-MSB5 antibody and an MSB5-HRP conjugate. The assay sample and buffer are incubated together with MSB5-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the MSB5 concentration since MSB5 from samples and MSB5-HRP conjugate compete for the anti-MSB5 antibody binding site. Since the number of sites is limited, as more sites are occupied by MSB5 from the sample, fewer sites are left to bind MSB5-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The MSB5 concentration in each sample is interpolated from this standard curve.

uniprot summary :
maspin: Tumor suppressor. It blocks the growth, invasion, and metastatic properties of mammary tumors. As it does not undergo the S (stressed) to R (relaxed) conformational transition characteristic of active serpins, it exhibits no serine protease inhibitory activity. Interacts with IRF6. Normal mammary epithelial cells. Belongs to the serpin family. Ov-serpin subfamily. 2 isoforms of the human protein are produced by alternative splicing. Chromosomal Location of Human Ortholog: 18q21.33. Cellular Component: extracellular space; cytoplasm. Molecular Function: serine-type endopeptidase inhibitor activity; protein binding. Biological Process: extracellular matrix organization and biogenesis; morphogenesis of an epithelium; cell motility; regulation of epithelial cell proliferation
