Biotium CD63 (Late Endosomes Marker)(LAMP3/2881), Biotin conjugate, 0.1mg/mL
This MAb recognizes protein of 26 kDa-60 kDa, which is identified as CD63. The tetraspanins are integral membrane proteins expressed on cell surface and granular membranes of hematopoietic cells and are components of multi-molecular complexes with specific integrins. The tetraspanin CD63 is a lysosomal membrane glycoprotein that translocates to the plasma membrane after platelet activation. CD63 is expressed on activated platelets, monocytes and macrophages, and is weakly expressed on granulocytes, T cell and B cells. It is located on the basophilic granule membranes and on the plasma membranes of lymphocytes and granulocytes. CD63 is a member of the TM4 superfamily of leukocyte glycoproteins that includes CD9, CD37 and CD53, which contain four transmembrane regions. CD63 may play a role in phagocytic and intracellular lysosome-phagosome fusion events. CD63 deficiency is associated with Hermansky-Pudlak syndrome and is strongly expressed during the early stages of melanoma pr

AdipoGen Biotin Sulfone
Chemical. CAS 40720-05-6. Formula C10H16N2O5S. Molecular Weight 276.31. Biotin sulfone is an oxidized form of biotin and is as efficient as biotin in streptavidin binding and it binds to avidin with a binding ratio of 0.332 compared with biotin. Biotinylated synthetic oligosaccharides are an attractive tool, as streptavidin coated plates and beads are commercially available and widely use in serological assays. As biotin is chemically reactive, and not compatible with carbohydrate protecting group manipulation, the use of biotin sulfone tagged oligomannosides BSTO for antigen immobilization in candidiasis or allergy diagnosis has been used. The use of biotin sulfone also offers a convenient solution for both oligosaccharide synthesis and immobilization on microspheres and surface plasmon resonance sensors.
