Product Overview
This rabbit polyclonal antibody recognizes thioredoxin-interacting protein (gene TXNIP) in human, mouse and rat samples and is validated for Western blot, flow cytometry and ELISA. The predicted molecular weight is 43.7 kDa, and the supplier reports an observed band at about 50–55 kDa.
Thioredoxin-interacting protein (TXNIP) is an α-arrestin family protein that binds and inhibits reduced thioredoxin, raising cellular oxidative stress. It is strongly induced by glucose and helps regulate glucose uptake and metabolism, and it has been linked to NLRP3 inflammasome activation and to cell cycle arrest, making it a focus in diabetes and metabolic research.

Immunogen
Recombinant human TXNIP fragment (Asp122–Asn152), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 93.5%.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places thioredoxin-interacting protein in the cytoplasm and nucleus. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
