The Human CD63 (Tetraspanin 30) ELISA quantitates CD63 in serum and plasma.
原理方法
The Human Tetraspanin 30 (CD63) solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) is designed to measure the concentration of Tetraspanin 30 (CD63) in biological samples. A target-specific antibody has been pre-coated in the wells of the supplied microplate. Samples, standards, or controls are added into these wells and bind to the immobilized (capture) antibody.
The sandwich complex is formed by the addition of a second (HRP-linked) detection antibody specific to Tetraspanin 30 (CD63). Excess reagents are washed from the plate.
A substrate solution is added that reacts with the enzyme-antibody-target complex to produce a measurable signal. The enzyme-substrate reaction is terminated by the addition of stop solution. The intensity of the signal, measured spectrophotometrically at 450 ± 2 nm, is directly proportional to the concentration of Tetraspanin 30 (CD63) present in the original specimen.
Rigorous validation:
Each manufactured lot of this ELISA kit is quality tested for criteria such as sensitivity, specificity, precision, and lot-to-lot consistency. See manual for more information on validation.

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.
