The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition.\nTo minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eAssay procedure summary\u003c\/b\u003e: 1.

Incubate 1 hour at 37°C;\n4. Aspirate and wash 3 times;\n5. Add 100µL prepared Detection Reagent B. Incubate 30 minutes at 37°C;\n6. Aspirate and wash 5 times;\n7. Add 90µL Substrate Solution. Incubate 10-20 minutes at 37°C;\n8. Add 50µL Stop Solution. Read at 450nm immediately.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eTest principle\u003c\/b\u003e: 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 Secreted Frizzled Related Protein 1 (SFRP1). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Secreted Frizzled Related Protein 1 (SFRP1). 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 Secreted Frizzled Related Protein 1 (SFRP1), 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 Secreted Frizzled Related Protein 1 (SFRP1) in the samples is then determined by comparing the O.D. of the samples to the standard curve.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eResearch Area\u003c\/b\u003e: Signal transduction;\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReferences Citing This Product\u003c\/b\u003e: \u003ca href=\"http:\/\/www.ncbi.nlm.nih.gov\/pubmed\/23025387\"\u003eBiomarkers and cytokines of bone turnover: extensive evaluation in a cohort of patients with ankylosing spondylitis\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"http:\/\/www.ncbi.nlm.nih.gov\/pubmed\/26712519\"\u003eWnt Inhibition is Dysregulated in Gliomas and its Re-Establishment Inhibits Proliferation and Tumor Sphere Formation\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/28153008\"\u003eCorrelation of blood bone turnover biomarkers and Wnt signaling antagonists with AS, DISH,OPLL, and OYL.\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/28178355\"\u003eEffects of exercise training on circulating levels of Dickkpof-1 and secreted frizzled-related protein-1 in breast cancer survivors: A pilot single-blind randomized controlled trial.\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"http:\/\/journals.plos.org\/plosone\/article?id=10.1371\/journal.pone.0171771\"\u003eEffects of exercise training on circulating levels of Dickkpof-1 and secreted frizzled-related protein-1 in breast cancer survivors: A pilot single-blind randomized controlled trial\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/28645312\"\u003ePHF21B overexpression promotes cancer stem cell-like traits in prostate cancer cells by activating the Wnt\/β-catenin signaling pathway\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"https:\/\/onlinelibrary.wiley.com\/doi\/abs\/10.1002\/jbm4.10179\"\u003eLow serum levels of DKK2 predict incident low‐impact fracture in older women\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/32041953\/\"\u003eImmunological history governs human stem cell memory CD4 heterogeneity via the Wnt signaling pathway\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":48696797954148,"sku":"SEF880Hu","price":996.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_ada4650b-6d68-4e85-bd66-a474f00d27a0.jpg?v=1783139976","url":"https:\/\/www.genebiosystems.com\/en-de\/products\/sfrp1-elisa-kit-for-human","provider":"GeneBio ","version":"1.0","type":"link"}
