Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro257 of human LAMP3/CD208 protein.

Background

Lysosome-associated membrane proteins (LAMPs) are a family of proteins present predominantly on the membrane of lysosomes. Five members have been identified so far (LAMP1, LAMP2, LAMP3, CD68/Macrosialin/LAMP4, and BAD-LAMP/LAMP5). LAMP proteins are involved in many different aspects of cell biology and can influence cellular processes, such as phagocytosis, autophagy, lipid transport, and aging. Their expression varies among different tissues (1). LAMP3, also known as CD-LAMP and CD208, is highly expressed only in certain cell types and differentiation stages. LAMP3 is specifically expressed by human dendritic cells (DCs) upon activation and therefore serves as a marker of human DC maturation, but is not expressed by DCs in mouse (2-4). Its expression is associated with poor prognosis of certain tumors, and the locus where it is encoded was identified as a risk factor for Parkinson's disease (PD) (5).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v nonfat dry milk, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
