Human CD200 ELISA Kit

DatasheetComponentsSpecific ReferencesReviewsRelated Products
Principle Of The Test
Solid Phase Sandwich ELISA
Intended Use
The kit has been verified by high purity Human CD200 recombinant protein.
The use of this kit for natural samples need be validated by the end user due to the complexity of natural targets and unpredictable interference.
Assay Range
62.5-4000 pg/mL
The minimum detectable dose of Human CD200 is typically less than 7.95 pg/mL. The MDD was determined by adding three standard deviations to the mean optical density value of twenty zero standard replicates and calculating the corresponding concentration.
Materials Provided
1. 96 well microplate coated with Capture Antibody
2. Detection Antibody conjugated to HRP
3. Standards
4. Wash Buffer Concentrate
5. Dilution Buffer Concentrate
6. Color Reagent A
7. Color Reagent B
8. Stop Solution
Unopened Kit: Store at 2 - 8℃
Opened/Reconstituted Reagents: Please refer to CoA
CD200 Background

CD200 (OX-2) is a cell surface glycoprotein that imparts immune privileges by suppressing alloimmune and autoimmune responses through its receptor, CD200R, expressed primarily on myeloid cells. Signals delivered through the CD200:CD200R axis have been shown to play an important role in the regulation of anti-tumor immunity, and overexpression of CD200 has been reported in a number of malignancies, including CLL, as well as on cancer stem cells. The role of CD200-CD200R signaling in immune regulation of the central nervous system has become a popular field of research in recent years. Many studies have shown that there is a close correlation between CD200-CD200R, microglia activation, and Parkinson's disease (PD). The ability of CD200 to suppress myeloid cell activation is critical for maintaining normal tissue homeostasis but may also enhance the survival of migratory neoplastic cells. CD200 and CD200R associate via their respective N-terminal Ig-like domains. CD200 has been characterized as an important immunoregulatory molecule, increased expression of which can lead to decreased transplant rejection, autoimmunity, and allergic disease. Elevated CD200 expression has been reported to be associated with poor prognosis in a number of human malignancies. In addition, CD200 also plays an important role in prevention of graft rejection, autoimmune diseases and spontaneous abortion.
