CD107a (LAMP-1) Antibody (755-1079-94) in IHC (P)
Immunohistochemical analysis of CD107a (LAMP-1) was performed on FFPE human colon tissue. HIER was performed on de-paraffinized sections using eBioscience™ IHC Antigen Retrieval Solution - Low pH (10X) (Product # 00-4955-58) in Steamer for 30-mins, followed by a 5-min cool down, a 1-min wash with ddH2O, and then transferred to 1X PBS. Tissues were permeabilized with 0.1% Triton X-100 in 1X PBS for 30-mins, ... View More

Product Specific Information
Description: The eBioH4A3 monoclonal antibody reacts with human CD107a, also known as lysosomal-associated membrane protein-1 (LAMP-1). CD107a is a highly glycosylated protein of approximately 110kDa. It is predominantly expressed intracellularly in the lysosomal/endosomal membrane in nearly all cells. CD107a is transiently expressed on the cell surface of degranulating cytolytic T cells, and is also upregulated on the surface of activated platelets and some cancer cells.
Applications Reported: Purified anti-human CD107a (LAMP-1) has been reported for use in flow cytometric analysis, immunohistochemistry, immunocytochemistry, and immunoblotting. It has also been reported for use in surface staining in a flow cytometric based degranulation assay. (Fluorochrome conjugated eBioH4B4 (H4B4) is recommended for use in flow cytometry).
Applications Tested: This eBioH4A3 antibody has been tested by immunohistochemistry on formalin-fixed paraffin embedded human tissue using low pH antigen retrieval and can be used at 10 µg/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
Using conjugate solutions: Centrifuge the protein conjugate solution briefly in a microcentrifuge before use; add only the supernatant to the experiment. This step will help eliminate any protein aggregates that may have formed during storage, thereby reducing nonspecific background staining.
Target Information
LAMP1 (CD107a, lysosome-associated membrane protein-1) together with LAMP-2, is a major constituent of lysosomal membrane, 1-2% of total CD107a is found also on the plasma membrane. LAMP1 is a heavily glycosylated membrane protein which contains a putative signal peptide, 18 sites for N-linked glycosylation, a single membrane-spanning segment and a short (11 amino acid) cytosolic tail. The LAMP proteins are involved in lysosome biogenesis and are required for fusion of lysosomes with phagosomes. LAMP1 is a type 1 integral membrane protein that is transported from trans-Golgi network to endosomes and then lysosomes. Upon cell activation, LAMP1 transfer to the plasma membrane is dependent on a carboyxl-terminal tyrosine based motif (YXXI). Perturbation in the spacing between the tyrosine based motif relative to the membrane abolishes lysosome localization of LAMP1, and this mutant protein then cycles between the plasma membrane and the endosome. Cell surface LAMP1 (and LAMP2) have been shown to promote adhesion of human peripheral blood mononuclear cells (PBMC) to vascular endothelium, therefore, they are possibly involved in the adhesion of PBMC to the site of inflammation. Increased LAMP1 immunoreactivity is observed in neurons and glial cells surrounding senile plaques in Alzheimer's Disease (AD) cases, and is localized in medullary epithelial cells, single macrophages and lymphocytes in acute thymic involution. LAMP1 is a good marker of mast cell activation.
