Human LAMP1/CD107a Lumenal Domain Antibody Summary
Accession # P11279
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Detection of Human LAMP1/CD107a by Western Blot. Western blot shows lysates of SW13 human adrenal cortex adenocarcinoma cell line, Tera‑2 human embryonic lung carcinoma cell line, and human placenta tissue. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human LAMP1/CD107a Lumenal Domain Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4800) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for LAMP1/CD107a at approximately 90 - 120 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.
LAMP1/CD107a in THP-1 Human Cell Line. LAMP1/CD107a was detected in immersion fixed THP-1 human acute monocytic leukemia cell line using 10 µg/mL Sheep Anti-Human LAMP1/CD107a Lumenal Domain Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4800) for 3 hours at room temperature. Cells were stained with the NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (red; Catalog # NL010) and counterstained with DAPI (blue).

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.
