Mouse ELA2(Elastase 2, Neutrophil) ELISA Kit

Serine protease that modifies the functions of natural killer cells, monocytes and granulocytes. Inhibits C5a-dependent neutrophil enzyme release and chemotaxis (By similarity). Promotes blood coagulation (PubMed:20676107). Through the activation of the platelet fibrinogen receptor integrin alpha-IIb/beta-3, potentiates platelet aggregation induced by a threshold concentration of cathepsin G (CTSG) (By similarity). Cleaves and thus inactivates tissue factor pathway inhibitor (TFPI) (By similarity). Capable of killing E.coli, probably digests outer membrane protein A (ompA) in E.coli (PubMed:10947984) Assay Type: Sandwich. Sensitivity: 0.57 ng/mL. Standard: 100 ng/mL. Detection range: 1.57-100 ng/mL. Sample type: serum, plasma and other biological fluids. Assay length: 3.5h. Research Field: Enzyme & Kinase,Infection immunity,. Test principle: The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Mouse ELA2. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Mouse ELA2. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Mouse ELA2, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Mouse ELA2 in the samples is then determined by comparing the OD of the samples to the standard curve.
