Description

LAMP2, or lysosome-associated membrane glycoprotein 2, serves as a critical component of the lysosomal membrane where it plays essential roles in autophagy, lysosomal stability, and cellular homeostasis. This heavily glycosylated protein has garnered significant research attention due to its involvement in cardiovascular biology and its utility as a reliable marker for lysosomal compartments. Mutations in LAMP2 are associated with Danon disease, a condition characterized by cardiomyopathy and skeletal muscle weakness, making this target particularly relevant for researchers investigating cardiac pathophysiology and autophagy-related disorders.

This recombinant monoclonal antibody, clone 23G11, offers the reproducibility and consistency that demanding research protocols require. Because the antibody sequence is defined and produced recombinantly in rabbit host cells, researchers can expect uniform performance across experiments and between lot numbers, eliminating the variability often encountered with traditional hybridoma-derived antibodies. The affinity-chromatography purification ensures high purity, while the liquid formulation with glycerol-based buffer supports long-term stability when stored properly at -20°C or -80°C.

Validation in immunohistochemistry demonstrates reliable detection of LAMP2 in human placenta tissue using a standard paraffin-embedded workflow with citrate buffer antigen retrieval. At a 1:100 dilution, the antibody produced clear staining using HRP-polymer detection and DAB visualization on an automated Leica Bond system, confirming its suitability for routine histological applications. The recommended working range of 1:50 to 1:200 provides flexibility for optimization across different tissue types and detection systems.

This antibody supports researchers studying lysosomal biology, autophagy mechanisms, and cardiovascular disease pathways where LAMP2 function is implicated.

Target Background

Function

Plays an important role in chaperone-mediated autophagy, a process that mediates lysosomal degradation of proteins in response to various stresses and as part of the normal turnover of proteins with a long biological half-live. Functions by binding target proteins, such as GAPDH and MLLT11, and targeting them for lysosomal degradation. Plays a role in lysosomal protein degradation in response to starvation. Required for the fusion of autophagosomes with lysosomes during autophagy. Cells that lack LAMP2 express normal levels of VAMP8, but fail to accumulate STX17 on autophagosomes, which is the most likely explanation for the lack of fusion between autophagosomes and lysosomes. Required for normal degradation of the contents of autophagosomes. Required for efficient MHCII-mediated presentation of exogenous antigens via its function in lysosomal protein degradation; antigenic peptides generated by proteases in the endosomal/lysosomal compartment are captured by nascent MHCII subunits. Is not required for efficient MHCII-mediated presentation of endogenous antigens.; Modulates chaperone-mediated autophagy. Decreases presentation of endogenous antigens by MHCII. Does not play a role in the presentation of exogenous and membrane-derived antigens by MHCII.; (Microbial infection) Supports the FURIN-mediated cleavage of mumps virus fusion protein F by interacting with both FURIN and the unprocessed form but not the processed form of the viral protein F.
