Background Information
LAMP1 (also known as CD107a) is a 90-120 kDa heavily glycosylated membrane protein enriched in the lysosomal membrane. LAMP1 functions to provide selectins with carbohydrate ligands. This protein has also been shown to be a marker of degranulation on lymphocytes such as CD8+ and NK cells and may also play a role in tumor cell differentiation and metastasis.

Reviews
What customers say
All four reviews rate the antibody 5 stars. Users report excellent performance for Western blot and immunohistochemistry/immunocytochemistry. In WB, it detected LAMP1 clearly at 1:1000 dilution in HCC1937, H4, N2A, and 293T cells, with a distinct band between 95–130 kDa. For IHC/ICC, a 1:50 dilution on PFA-fixed NSC-34 cells yielded strong labeling. Overall, reviewers describe it as reliable and effective for LAMP1 detection across multiple cell types and applications.
