Species Reactivity:

Human

Source / Purification

Monoclonal antibody is produced by immunizing animals with human CD200 recombinant protein and reacts with an epitope surrounding Ala164.

Background

CD200 (OX2) and CD200R (OX2R) are membrane glycoprotein members of the Ig superfamily (1-3). CD200 is expressed by a range of cells, including neurons, epithelial cells, endothelial cells, fibroblasts, and lymphoid cells, while its receptor, CD200R, is found on myeloid and T cells (1-5). Interaction between CD200 and CD200R downregulates macrophage function and plays a role in immunosuppression and regulation of anti-tumor immune responses (3-7).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.

CD200 (E5I9V) XP® Rabbit mAb

Western Blotting Image 1: CD200 (E5I9V) XP® Rabbit mAb Expand Image
Western blot analysis of extracts from various cell lines using CD200 (E5I9V) XP® Rabbit mAb (upper) or β-Actin (D6A8) Rabbit mAb #8457 (lower).
Immunoprecipitation Image 1: CD200 (E5I9V) XP® Rabbit mAb Expand Image
Immunoprecipitation of CD200 from SK-MEL-28 cell extracts. Lane 1 is 10% input, lane 2 is Rabbit (DA1E) mAb IgG XP® Isotype Control #3900, and lane 3 is CD200 (E5I9V) XP® Rabbit mAb. Western blot analysis was performed using CD200(E5I9V) XP® Rabbit mAb as the primary antibody and Mouse Anti-rabbit IgG (Conformation Specific) (L27A9) mAb (HRP Conjugate) #5127 as the secondary antibody.
Immunohistochemistry Image 1: CD200 (E5I9V) XP® Rabbit mAb Expand Image
Immunohistochemical analysis of paraffin-embedded human gastric adenocarcinoma using CD200 (E5I9V) XP® Rabbit mAb performed on the Leica® BOND Rx.
Immunohistochemistry Image 1: CD200 (E5I9V) XP® Rabbit mAb Expand Image
Immunohistochemical analysis of paraffin-embedded human ovarian serous carcinoma using CD200 (E5I9V) XP® Rabbit mAb.
Immunohistochemistry Image 2: CD200 (E5I9V) XP® Rabbit mAb Expand Image
Immunohistochemical analysis of paraffin-embedded human renal cell carcinoma (left), prostate carcinoma (middle), or lymph node (right) using CD200 (E5I9V) XP® Rabbit mAb (top) or CD200 Rabbit mAb (bottom). These two antibodies detect independent, unique epitopes on human CD200. The similar staining patterns obtained with both antibodies help to confirm the specificity of the staining.
