Detection of LAMP-1/CD107a in THP‑1 Human Cell Line by Flow Cytometry. THP‑1 human acute monocytic leukemia cell line was stained with Mouse Anti-Human LAMP-1/CD107a Alexa Fluor® 594‑conjugated Monoclonal Antibody (Catalog # IC4800T, filled histogram) or isotype control antibody (Catalog # IC0041T, open histogram). To facilitate intracellular staining, cells were fixed with Flow Cytometry Fixation Buffer (Catalog # FC004) and permeabilized with Flow Cytometry Permeabilization/Wash Buffer I (Catalog # FC005).

Preparation and Storage

Background: LAMP-1/CD107a

Lysosome-associated membrane protein-1 (LAMP1), also known as CD107a, is a 100‑130 kDa member of the LAMP family of glycoproteins. It is expressed in lysosomal and plasma membranes of macrophages, NK and T-cells, and with LAMP2, is essential for the formation of phagolysosomes. On the cell surface, it also presents carbohydrates to selectins. Mature human LAMP1 is a 389 amino acid (aa) type I transmembrane glycoprotein. It contains a 354 aa luminal/extracellular domain (ECD) (aa 28‑381) and a 12 aa cytoplasmic tail (aa 405‑416). The ECD has two large looping regions (aa 28‑193 and 227‑381) plus multiple N- and O-linked glycosylation sites. There is one potential splice variant that shows a 26 aa substitution in the signal sequence. Over aa 28‑380, human LAMP1 shares 64% aa identity with mouse LAMP1.
