Antigen: adenovirus expressing full-length recombinant mouse CD36 · Clone designation: JC63.1 · Host: CD36 null mouse · Isotype: IgA · Application(s): FC and functional blocking · CD36 is a type-B scavenger receptor that is necessary for the formation of foam cells and thereby atherosclerotic lesions.^1,2,3,4 This membrane glycoprotein can internalize fatty acids which activate PPARγ and stimulate further expression of CD36.^5,6 This positive feedback loop combined with the murine CD36 knock-out studies reinforces the importance of CD36 in lipid metabolism. Additionally CD36 is needed for the phagocytosis of P. falciparum infected erythrocytes, retinal pigment epithelial cell photoreceptor fragments, and post-apoptotic monocytes and neutrophils.^7,8,9,10 CD36 expression has been monitored during hematopoietic cell differentiation and may be an indicator of tumor spreading in lymphocytic leukemia.¹¹ Positive controls include cells from adipose and heart tissue, platelets, and macrophages. Cayman Chemical’s CD36 monoclonal antibody is recommended for flow cytometry on CD36-containing cells of murine, rat, and human origin. The antibody can also be used to antagonize CD36-mediated cellular activity. The antibody does not work well for Western blot analysis of CD36.
