Product Overview
Clone 23U49 is a rabbit monoclonal antibody that recognizes ubiquitin carboxyl-terminal hydrolase 28 (gene USP28) in human, mouse and rat samples and is validated for Western blot. The predicted molecular weight is 122.5 kDa, and the supplier reports an observed band at about 135 kDa.
USP28 is a deubiquitinating enzyme that protects several proteins from degradation. It stabilizes the MYC oncoprotein by counteracting the ubiquitin ligase FBW7, and it supports DNA damage checkpoint signaling through proteins such as claspin and 53BP1. USP28 is studied in the DNA damage response and cancer.

Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places ubiquitin carboxyl-terminal hydrolase 28 in the nucleus. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
