Product Overview
This rabbit polyclonal antibody detects swi5-dependent recombination DNA repair protein 1 homolog (gene SFR1) in human, mouse and rat samples and is validated for Western blot and flow cytometry. The predicted molecular weight is 28.3 kDa, and the supplier reports an observed band at about 22 kDa.
SFR1 (also called MEI5) partners with SWI5 to form the SWI5–SFR1 complex, which assists the recombinase RAD51 during homologous recombination repair of DNA double-strand breaks. It has also been reported to modulate estrogen receptor alpha-driven transcription.

Immunogen
Synthetic peptide from the middle region of human SFR1.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places swi5-dependent recombination DNA repair protein 1 homolog in the nucleus. Tissue expression noted by UniProt (human): Widely expressed. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
