LAMP1/CD107a in HeLa Human Cell Line. LAMP1/CD107a was detected in formaldehyde fixed HeLa human cervical epithelial carcinoma cell line using Sheep Anti-Human LAMP1/CD107a Alexa Fluor® 488‑conjugated Antigen Affinity-purified Polyclonal Antibody (Catalog # IC7985G) at 1:10 dilution for 3 hours at room temperature and counterstained with DAPI (blue). Specific staining was localized to lysosomes. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.
Preparation and Storage

LAMP1 (Lysosome-associated membrane protein-1; also 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.
