特徴

• Kunitz-type protease inhibitor 2 is an enzyme inhibitor that in humans is encoded by the SPINT2 gene. This gene encodes a transmembrane protein with two extracellular Kunitz domains that inhibits a variety of serine proteases. The protein inhibits HGF activator which prevents the formation of active hepatocyte growth factor. And this gene is a putative tumor suppressor, and mutations in this gene result in congenital sodium diarrhea. Multiple transcript variants encoding different isoforms have been found for this gene.
• Sample Type:Cell lysates, cell culture supernates, serum, plasma (heparin or EDTA).
• Intended Use:Sandwich High Sensitivity BioAssay™ ELISA kit for Quantitative Detection of Mouse HAI-2/SPINT2.
• Sensitivity:<10pg/ml
• Range:31.2pg/ml-2000pg/ml
• Specificity:Recognizes natural and recombinant Mouse HAI-2/SPINT2. There is no detectable cross-reactivity with other relevant proteins.
• Test Principle:This Mouse HAI-2/SPINT2 BioAssay™ ELISA Kit was based on standard sandwich enzyme-linked immune- sorbent assay technology. A specific for HAI-2/SPINT2 has been precoated onto 96-well plates. Standards(Expression system for standard: NSO; Immunogen sequence: R30-K140) and test samples are added to the wells, a biotinylated detection specific for HAI-2/SPINT2 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the Mouse HAI-2/SPINT2 amount of sample captured in plate.
