It is expressed on the surface of osteoclasts, dendritic cells and facilitates immune signaling. RANK is involved in their activation upon ligand binding. RANKL (Receptor Activator for Nuclear Factor κ B Ligand) is found on the surface of stromal cells, osteoblasts, and T cells. RANKL and RANK have an essential role in the brain. RANK and RANKL appear to be important regulators of interactions between T cells and dendritic cells.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003ePrinciple of the Assay:\u003c\/strong\u003e This kit was based on sandwich enzyme-linked immune-sorbent assay technology. Anti-RANK polyclonal antibody was pre-coated onto 96-well plates. And the biotin conjugated anti-RANK polyclonal antibody was used as detection antibodies. The standards, test samples and biotin conjugated detection antibody were added to the wells subsequently, and wash with wash buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with wash buffer. TMB substrates were 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 RANK amount of sample captured in plate. Read the O.D. absorbance at 450nm in a microplate reader, and then the concentration of RANK can be calculated.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eStorage and Expiration:\u003c\/strong\u003e Store at 2-8℃ for 6 months, or at -20℃ for 12 months.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eRange:\u003c\/strong\u003e 62.5 pg\/ml - 4000 pg\/ml\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSensitivity:\u003c\/strong\u003e \u0026lt; 2 pg\/ml","brand":"Biospes","offers":[{"title":"96T","offer_id":50409036448024,"sku":"BEK1192","price":500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/Biospes-logo_ff5568fb-524b-4104-88d2-1e259a1ba939.jpg?v=1750988660","url":"https:\/\/danabiosci.com\/products\/bek1192","provider":"Dana Bioscience","version":"1.0","type":"link"}
