Product Specific Information

Description: The eBioH4B4 monoclonal antibody reacts with human CD107b, also known as lysosomal-associated membrane protein-2 (LAMP-2). CD107b is a highly glycosylated, type I transmembrane protein of approximately 105 kDa. It is expressed intracellularly in lysosomal/endosomal membranes in nearly all cells. It is also expressed on the surface of degranulating T cells (to a lesser extent than CD107a) and activated platelets as well as some cancer cells. In humans, mutations in CD107b results in a lysosomal glycogen storage disorder, known as Danon disease.

Applications Reported: This eBioH4B4 (H4B4) antibody has been reported for use in intracellular staining followed by flow cytometric analysis. It has also been reported for use in surface staining in a flow cytometric based degranulation assay.

Applications Tested: This eBioH4B4 (H4B4) antibody has been pre-titrated and tested by intracellular staining and flow cytometric analysis of Jurkat cell line. This can be used at 5 µL (0.25 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test.

Excitation: 488 nm; Emission: 519 nm; Laser: Blue Laser.

Filtration: 0.2 µm post-manufacturing filtered.

Target Information

LAMP2 (Lysosome-associated membrane glycoprotein 2, CD107b) is a member of a family of membrane glycoproteins. LAMP2 provides selectins with carbohydrate ligands, and may play a role in tumor cell metastasis, and have a function in the protection, maintenance, and adhesion of the lysosome. Prior to posttranslational modification, LAMP2 is approximately 46 kDa polypeptide. Mature, functional LAMP2 is extensively glycosylated with a variety of different N-linked and O-linked oligosaccharides with a total molecular weight of about 100-130 kDa. LAMP 2 has a structure comprised of a large amino-terminal intra-lysosomal domain, a hydrophobic trans-membrane domain, and a short carboxyl-terminal cytoplasmic tail. LAMP2 is used to monitor a very selective form of autophagy called chaperone-mediated autophagy. LAMP 2 has a structure comprised of a large amino-terminal intra-lysosomal domain, a hydrophobic trans-membrane domain, and a short carboxyl-terminal cytoplasmic tail. The LAMP protein has 3 variant forms: LAMP-2A, -2B, and 2C. LAMP2, together with CD107a/LAMP-1, is a major constituent of lysosomal membrane. The LAMP proteins are involved in lysosome biogenesis and are required for fusion of lysosomes with phagosomes, and LAMP2 is an important regulator in successful phagosomal maturation. LAMP2 deficiency causes an accumulation of autophagosomes in many tissues leading to cardiomyopathy and myopathy (Danon`s disease).
