Scientific Data Images for Human TSG101 Antibody

Detection of TSG101 in SW480 Cells.

TSG101 was detected in immersion fixed SW480 Human Colorectal Adenocarcinoma Cells using Mouse Anti-Human TSG101 Monoclonal Antibody (Catalog # MAB11438) at 8 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cell cytoplasm. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Background: TSG101

TSG101 is an essential member of the ESCRT-1 complex which regulates the sorting of ubiquitinated proteins to endosomes, facilitating vesicular trafficking and is implicated in normal development.  It is also involved in regulating transcription, protein sorting, biogenesis of multi-vesicular bodies, and viral budding.  Dysregulation of ESCRT proteins occurs in the development of various human diseases, including many types of cancers and neurodegenerative diseases.  TSG101 is an established cancer-associated gene and truncated aberrantly spliced mRNAs have been reported in various types of cancer. TSG101 is also commonly used as a marker protein for exosomes.
