Product Overview
This rabbit polyclonal antibody detects signal transducing adapter molecule 2 (gene STAM2) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF and ELISA. The predicted molecular weight is 58.2 kDa, and the supplier reports an observed band at about 65–70 kDa.
STAM2 (signal transducing adapter molecule 2) is a close relative of STAM1 that pairs with HGS in the ESCRT-0 complex. This complex binds ubiquitinated receptors on endosomes and routes them for lysosomal degradation, and STAM2 also participates in cytokine and growth factor signaling.

Immunogen
Recombinant human STAM2 fragment (Lys134–Leu525), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 82.7% and 79.6%, respectively.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places signal transducing adapter molecule 2 in the cytoplasm and early endosome membrane. Tissue expression noted by UniProt (human): Ubiquitously expressed. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
