Background Information
CHCHD4, a component of human mitochondria, belongs to a protein family. It functions as chaperone and catalyzes the formation of disulfide bonds in substrate proteins, such as COX17. It is required for the import and folding of small cysteine-containing proteins (small Tim) in the mitochondrial intermembrane space (IMS).

Reviews
What customers say
Users report strong Western Blot performance with clear, specific bands at 1:1000 dilution in HEK293T and HeLa cells, with no aspecific signal. One user noted successful colocalization with TOMM20 in immunofluorescence but observed some unspecific cytosolic binding, resulting in a moderate rating. Overall, the antibody is well-regarded for WB applications, while IF results are more mixed, with potential non-specific interactions to be aware of.
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
Veronica (Verified Customer) (10-17-2023) | First time I find an anti-CHCHD4 antibody that works fine. We are testing it in IF as well, but till now I am already really happy with the result in WB. No aspecific signal, clear band. Reccomended! Conditions: Gradient gel 8-15% Ab’: 1:1000 in 5% milk O/N

Süleyman (Verified Customer) (01-23-2022) | CHCHD4 antibody (Green) is used 1:100 dilution (2 hour at RT) and 1:700 of Alexa Fluor 488 secondary antibody (1 hour RT). 4% Paraformaldehyde fixation for 10 min at RT. Permeabilization with 0.3% Triton X for 10-15 minutes at RT. 5% FBS in PBS used for blocking for 1 hour at RT. The image is colocalized with TOMM20 (Red). Blue is DAPI. As you can see there is colocalization with TOMM20 as CHCHD4 supposed to be in IMS but I also see unspecific bindings in cytosolic proteins. Therefore my rating is 3 as it might be binding unspecifically.
