Description

TSG101 serves as a critical component of the ESCRT-I complex, playing essential roles in multivesicular body formation, viral budding, and cytokinesis. This protein has garnered significant attention in exosome research, where it functions as a widely recognized marker, as well as in studies examining how enveloped viruses exploit host cellular machinery for their release. Understanding TSG101 biology provides valuable insights into membrane trafficking, autophagy, and tumor suppression pathways.

This recombinant monoclonal antibody, clone 13C11, offers the reproducibility that demanding research requires. Because it is produced from a defined genetic sequence rather than traditional hybridoma methods, you can expect consistent performance across experiments and between lot numbers. This sequence-defined production eliminates the batch variability that can complicate long-term studies or multi-site collaborations, giving you confidence that your results reflect true biological differences rather than reagent inconsistencies.

The antibody has been validated for immunofluorescence and flow cytometry applications using human samples. Immunofluorescence staining of HeLa cells demonstrates clear signal when used at dilutions between 1:50 and 1:200, with overnight incubation at 4°C following standard fixation and permeabilization protocols. Flow cytometry validation, also performed in HeLa cells, shows distinct population separation from isotype control at 1:100 dilution, confirming reliable detection of endogenous TSG101 in this human cell line.

Whether you are characterizing exosome populations, investigating viral assembly mechanisms, or exploring ESCRT pathway dynamics, this antibody provides a dependable tool for visualizing TSG101 localization and expression. Its compatibility with both imaging and quantitative flow-based approaches offers flexibility for researchers working across multiple experimental platforms.

Target Background

Function(From Uniprot)

Component of the ESCRT-I complex, a regulator of vesicular trafficking process. Binds to ubiquitinated cargo proteins and is required for the sorting of endocytic ubiquitinated cargos into multivesicular bodies (MVBs). Mediates the association between the ESCRT-0 and ESCRT-I complex. Required for completion of cytokinesis; the function requires CEP55. May be involved in cell growth and differentiation. Acts as a negative growth regulator. Involved in the budding of many viruses through an interaction with viral proteins that contain a late-budding motif P-[ST]-A-P. This interaction is essential for viral particle budding of numerous retroviruses. Required for the exosomal release of SDCBP, CD63 and syndecan. It may also play a role in the extracellular release of microvesicles that differ from the exosomes.
