CD63 Antibody (MA1-19281) in ICC/IF
Immunofluorescence analysis of CD63 was performed using 70% confluent log phase U-87 MG cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes, and blocked with 2% BSA for 1 hour at room temperature. The cells were labeled with CD63 Mouse Monoclonal Antibody (MEM-259) (Product # MA1-19281) at 5 µg/mL in 0.1% BSA, incubated at 4 degree celsius overnight and then with Goat anti-Mouse IgG (H+L) Superclonal™ Recombinant Secondary Antibody, Alexa Fluor® 488 conjugate (Product # ...

Product Specific Information
This antibody reacts with an extracellular/luminal epitope of CD63 (LAMP-3), a 40-60 kDa tetraspan glycoprotein expressed by granulocytes, platelets, T cells, monocytes/macrophages and endothelial cells. Cell surface exposition of CD63 is usually activation-dependent.
Target Information
CD63, also known as LAMP-3, is a glycoprotein belonging to the tetraspanin family, primarily located in late endosomes, lysosomes, and secretory vesicles across various cell types. It is expressed intracellularly in resting platelets and basophils, but upon activation, CD63 translocates to the plasma membrane, making it a widely used marker for basophil activation. Unlike basophils, mast cells can expose CD63 without activation. CD63 is expressed on activated platelets, monocytes, macrophages, and granulocytes, as well as endothelial cells, fibroblasts, and smooth muscle cells. It interacts with integrins (such as VLA-3 and VLA-6) and TIMP-1, playing roles in mediating allergic responses, phagocytosis, and cell migration. Additionally, CD63 is involved in the regulation of H/K-ATPase trafficking and ROMK1 channels, and serves as a T-cell costimulation molecule. CD63 expression can be used to predict prognosis in early-stage carcinomas and is identical to the melanoma-associated antigen ME491 and the platelet antigen PTLGP40. Diseases associated with CD63 dysfunction include melanoma and Hermansky-Pudlak Syndrome, highlighting its significance in both immune responses and disease processes.
