Product details:
Human CD200 ELISA Kit (ab267806) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of CD200 protein in cell culture media, edta plasma, hep plasma, serum, and cit plasma. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human CD200 with 13 pg/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (
ab203359
) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.
Cluster of Differentiation 200 (CD200), also known as OX-2 membrane glycoprotein, is a 32 kDa protein that contains six glycosylation sites. CD200 belongs to the immunoglobulin superfamily of cell surface proteins and is found present at the first line of immune defense in which is involved in immunoregulatory functions such as to costimulates T-cell proliferation. ab267806 recognizes the extracellular domain of the full length transmembrane protein.

CD200 also known as OX2 is a cell surface glycoprotein with a molecular mass of approximately 43 kDa. It plays a mechanical role in immune response regulation. CD200 expression occurs on several cell types such as thymocytes neurons vascular endothelium and splenocytes including cynomolgus monkey splenocytes. This protein generally modulates interactions between cells sending inhibitory signals through its receptor CD200R found on myeloid cells and certain lymphoid cells.
Biological function summary
CD200 regulates the immune system by inhibiting inflammatory responses and maintaining immune homeostasis. It does not act as part of a significant multi-protein complex but directly interacts with CD200R. This interaction promotes an anti-inflammatory state and is important in preventing autoimmune diseases and excessive tissue damage. The expression of CD200 is also an indicator of immune tolerance in various tissues.
Pathways
CD200 is involved in immune regulatory pathways. It plays a pivotal role in the suppression of immune responses through the CD200-CD200R signaling pathway. This pathway is vital for dampening inflammatory processes related to autoimmune reactions and is consequently linked to the maintenance of tissue homeostasis. Proteins related to CD200 through these pathways include CD200R and other molecules involved in immune checkpoint pathways.
CD200 expression correlates with several conditions including cancer and autoimmune diseases. The overexpression of CD200 in certain tumors promotes immune evasion thereby favoring tumor progression. Conversely reduced CD200 levels are associated with autoimmune disorders where a hyperactive immune system attacks self-tissues. Through these disease contexts CD200 operates alongside proteins such as CD200R and OX90 impacting disease progression and immune system modulation.
