Species cross-reactivity is determined by western blot. Species enclosed in parentheses are predicted to react based on 100% sequence homology.
Specificity / Sensitivity
LAMP1 (D2D11) XP® Rabbit mAb recognizes endogenous levels of total LAMP1 protein.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a recombinant protein fragment of human LAMP1 protein.
Western blot analysis of extracts from various cell lines using LAMP1 (D2D11) XP® Rabbit mAb.
Lysosome-associated membrane protein 1 and 2 (LAMP1 and LAMP2) are two abundant lysosomal membrane proteins (1,2). Both are transmembrane proteins and are heavily glycosylated at the amino-terminal luminal side of the lysosomal inner leaflet, which protects the proteins from proteolysis (3). The carboxy terminus of LAMP1 is exposed to the cytoplasm and contains a tyrosine sorting motif that targets LAMP to lysosomal membranes (4). LAMP1 and LAMP2 are 37% homologous in their protein sequences. Both LAMP1 and LAMP2 are involved in regulating lysosomal motility during lysosome-phagosome fusion and cholesterol trafficking (5,6).
