Background Information
COX4I1, also named as COX4 and COXIV-1, belongs to the cytochrome c oxidase IV family. It is one of the nuclear-coded polypeptide chains of cytochrome c oxidase, the terminal oxidase in mitochondrial electron transport. COX4I1 is a marker for mitochondria. It has two isoforms (isoform 1 and 2). Isoform 1(COX4I1) is ubiquitously expressed and isoform 2 is highly expressed in lung tissues. COX4I1 is commonly used as a loading control. This antibody is specific to COX4I1 and do not cross reacts with COX4I2.

Reviews
What customers say
Users report positive experiences with this antibody across applications. One reviewer found it effective for immunohistochemistry on mouse retina cryosections at a 1:100 dilution, noting it worked well with overnight incubation at 4°C and recommending it. Another reviewer used it as a mitochondrial loading control for Western blot on mouse kidney tissue at 1:1000 dilution, rating it highly despite a minor blotting issue on their end. Overall, the antibody is well-received for its reliability in both IHC and WB applications.
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
Pooja (Verified Customer) (09-08-2025) | worked well in Mouse retina cryosection incubated with 1:100 CoxIV antibody at 4 degree overnight. Recommended.
