Immunofluorescent analysis of LAMP-2 (green) in NIH/3T3 cells. Cells were fixed with 4% paraformaldehyde, permeabilized with 0.1% Triton X-100 in PBS, and blocked with 1% Blocker BSA (Product # 37525), each for 15 minutes at room temperature. Cells were stained with a LAMP-2 polyclonal antibody (Product # PA1-655) at a concentration of 20ug/ml in 1% Blocker BSA in PBS (right panel), or incubated in blocking buffer alone as a negative control (left panel) overnight at 4C, and then incubated with a Dylight 488-conjugated goat anti-rabbit IgG secondary antibody (Product # 35552) at a dilution of 1:1000 for 1 hour at room temperature. Nuclei (blue) were stained with DAPI (Product # 46190). Images were taken on a Thermo Scientific ToxInsight Instrument at 20X magnification.

PA1-655 detects lysosome-associated membrane protein-2 (LAMP2) from rat, mouse and human tissues.
PA1-655 has been successfully used in Western blot, immunofluorescence, and immunohistochemistry. By Western blot, this antibody detects glycosylated and non-glycosylated LAMP-2, depending on the lysis buffer used.
PA1-655 immunizing peptide corresponds to amino acid residues 400-411 from rat LAMP2. This sequence is completely conserved between rat, mouse, and guinea pig LAMP2. PA1-655 immunizing peptide (Cat. # PEP-039) is available for use in neutralization and control experiments.
Lysosomes are membrane-bound vacuoles which play a critical role in cellular metabolism. These organelles participate in endocytosis, the synthesis and assembly of acid hydrolases, act as sites for digestion of foreign materials and for specialized autolytic cellular processes. Membrane-associated glycoproteins have an important role in normal lysosomal function. Prior to posttranslational modification, Lysosome-associated membrane protein-2 (LAMP-2) is an ~45 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 ~100-110 kDa. LAMP2 has a structure comprised of a large amino-terminal intra-lysosomal domain, a hydrophobic trans-membrane domain, and a short carboxyl-terminal cytoplasmic tail.
