Anti-TBRG4 Antibody - Identical to Abcam (ab180775)

Targeting TBRG4 (also annotated as FASTKD4, CPR2, and KIAA0948), this unconjugated rabbit polyclonal IgG reagent from Antibodies.com is raised against human transforming growth factor beta regulator 4, a 631-amino-acid mitochondrial protein that localizes to the mitochondrial matrix. TBRG4 carries an N-terminal mitochondrial targeting sequence followed by two FAST (Fas-activated serine/threonine kinase) domains and a C-terminal RAP RNA-binding region, and published work links it to processing and stabilization of mitochondrial mRNAs and rRNAs, as well as to cell cycle progression and stress-response signaling.

The reagent is supplied as 100 µl of liquid in a vial and is validated for western blot, immunofluorescence, and immunoprecipitation on human, mouse, and rat samples. Polyclonal recognition of multiple epitopes supports detection of denatured TBRG4 on membranes, native FASTKD4-containing complexes in immunoprecipitation lysates, and subcellular distribution of the protein in fixed cells by immunofluorescence.

Aliquot the working stock upon arrival and store at -20 °C, avoiding repeated freeze-thaw cycles; the vial is shipped refrigerated at 4 °C. Researchers working on mitochondrial RNA metabolism, electron transport chain biogenesis, apoptosis-related pathways, or TBRG4 involvement in tumor biology can integrate this primary antibody from Antibodies.com into routine immunodetection workflows.
