Description

In sandwich ELISAs, no cross-reactivity or interference with recombinant mouse CD200 is observed. Reconstitute at 0.5 mg/mL in sterile PBS. Endoxin level is <0.01 EU per 1 μg of the antibody by the LAL method.

CD200 is a type-1 membrane glycoprotein in the immunoglobulin superfamily, featuring two immunoglobulin domains. It is widely expressed on various cells, including B and T cells, keratinocytes, nerve cells, follicular dendritic cells, ovarian cells, and trophoblasts. CD200 interacts with CD200R on myeloid cells, inhibiting macrophage activation, reducing IL-6 production, and attenuating lymphocyte activation. It also prevents mast cell degranulation and decreases TNF-alpha and IL-13 secretion, playing a role in immune regulation and maternal tolerance. Homologues of CD200 are found in herpesviruses and poxviruses, indicating a conserved immune modulation function. CD200 has multiple alternatively spliced transcript variants, contributing to its functional diversity. Diseases linked to CD200 dysfunction include Mantle Cell Lymphoma and Primary Hypertrophic Osteoarthropathy, highlighting its importance in health and disease.
