CD107b (LAMP-2) Monoclonal Antibody (M3/84), FITC, eBioscience™

Product Specific Information

Description: The M3/84 monoclonal antibody reacts with mouse Mac-3, the 110 kDa protein expressed by mononuclear phagocytes. The Mac-3 antigen is expressed intracellularly by bone marrow monocyte lineage and is upregulated during macrophage differentiation. Peritoneal and tissue macrophages, dendritic cells, and endothelial cells express this antigen on their surface. It is reported that Mac-3 may be identical to CD107b.

Applications Reported: The M3/84 antibody has been reported for use in flow cytometric analysis.

Applications Tested: The M3/84 antibody has been tested by flow cytometric analysis of mouse bone marrow and thioglycolate-elicited peritoneal exudates cells and can be used at less than or equal to 0.5 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. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.

Excitation: 488 nm; Emission: 520 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).
