Ladner et al. (1987) showed that there are 2 forms of M-CSF, with 224 and 522 amino acids, resulting from alternative splicing. It is a hematopoietic growth factor that is involved in the proliferation, differentiation, and survival of monocytes, macrophages, and bone marrow progenitor cells. It released by osteoblasts (as a result of endocrine stimulation by parathyroid hormone) exerts paracrine effects on osteoclasts. M-CSF binds to receptors on osteoclasts inducing differentiation, and ultimately leading to increased plasma calcium levels—through the resorption (breakdown) of bone. More recently, it was discovered that CSF-1 and its receptor CSF1R are implicated in the mammary gland during normal development and neoplastic growth.\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-M-CSF polyclonal antibody was pre-coated onto 96-well plates. And the biotin conjugated anti-M-CSF 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 M-CSF amount of sample captured in plate. Read the O.D. absorbance at 450nm in a microplate reader, and then the concentration of M-CSF 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; 10 pg\/ml","brand":"Biospes","offers":[{"title":"96T","offer_id":50409027633432,"sku":"BEK1146","price":500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/Biospes-logo_ab9fbbdd-920f-4ec6-94f6-eaf28f10e64b.jpg?v=1750988556","url":"https:\/\/danabiosci.com\/products\/bek1146","provider":"Dana Bioscience","version":"1.0","type":"link"}
