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 Lumenal Domain Biotinylated Antigen Affinity-purified Polyclonal Antibody (Catalog # BAF4800) at 15 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Streptavidin (orange; Catalog # NL999) and counterstained with DAPI (blue). Specific staining was localized to lysosomes.

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.
