ELISA WNT1-inducible-signaling pathway protein 2 (WISP2)

Reactivity: (Homo sapiens) UniProt:O76076 Abbreviation:WISP2 Alternative Names:CCN5; CT58; CTGF-L; OTTHUMP00000063227|connective tissue growth factor-like protein|wnt-1 signaling pathway protein 2 Application:ELISA Range:0.312-20 ng/mL Sensitivity:0.117 ng/mL Intra-AssayCV:?6.4% Inter-AssayCV:?8.5% Recovery:0.89 Sample Type:Serum, Plasma, Other biological fluids Detection Method:Sandwich Analysis Method??:Quantitive Test principle:This assay employs a two-site sandwich ELISA to quantitate WISP2 in samples. An antibody specific for WISP2 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyWISP2 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjµgated antibody specific for WISP2 is added to the wells. After washing, Streptavidin conjµgated 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 WISP2 bound in the initial step. The color development is stopped and the intensity of the color is measured. Product Overview:WISP2 encodes a member of the WNT1 inducible signaling pathway (WISP) protein subfamily, which belongs to the connective tissue growth factor (CTGF) family. WNT1 is a member of a family of cysteine-rich, glycosylated signaling proteins that mediate diverse developmental processes. The encoded protein lacks the CT domain which is implicated in dimerization and heparin binding. It is 72% identical to the mouse protein at the amino acid level. This gene may be downstream in the WNT1 signaling pathway that is relevant to malignant transformation. Its expression in colon tumors is reduced while the other two WISP members are overexpressed in colon tumors. It is expressed at high levels in bone tissue, and may play an important role in modµLating bone turnover. Stability:The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. The loss rate was determined by accelerated thermal degradation test. Keep the kit at 37°C for 4 and 7 days, and compare O.D.values of the kit kept at 37°C with that of at recommended temperature. (referring from China Biological Products Standard, which was calcµLated by the Arrhenius equation. For ELISA kit, 4 days storage at 37°C can be considered as 6 months at 2 - 8°C, which means 7 days at 37°C equaling 12 months at 2 - 8°C).
