Background Information
MTCO2, also named as COII, COXII, and COX2, belongs to the cytochrome c oxidase subunit 2 family. It is the component of the respiratory chain that catalyzes the reduction of oxygen to water. Subunits 1-3 form the functional core of the enzyme complex. Subunit 2 transfers the electrons from cytochrome c via its binuclear copper A center to the bimetallic center of the catalytic subunit 1. Defects in COX2 are a cause of mitochondrial complex IV deficiency (MT-C4D). The antibody is specific to MTCO2.

Reviews
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
| FH Morgane (Verified Customer) (10-15-2025) | Works best on PVDF, very clear in total protein extract 
  | 
| FH Matthieu (Verified Customer) (09-24-2025) | Band is clearly visible at the correct size 
 | 
| FH Manon (Verified Customer) (09-24-2025) | vey nice band 
 | 
| FH Emilie (Verified Customer) (09-24-2025) | Bands appeared sharp and well defined under the chosen dilution. 
 | 
| FH Vignesh (Verified Customer) (09-03-2025) | It's a good product with reduced or no nonspecific bands. 
 | 
| FH Lenie (Verified Customer) (07-18-2025) | The IF staining and WB with the followed protocol of ProteinTech did not work on zebrafish tissue, even it describes on the site it should. Is there a possibility to send a working protocol about this Abies for zebrafish? Thanks. The bond which shows is a human patient sample. 
  | 
| FH Baptiste (Verified Customer) (05-23-2025) | Working perfectly 
  | 
| FH Edward (Verified Customer) (11-15-2022) | Used with 12 ug protein lysate MTCO2 works quite well, both with ECL detection and fluorescent secondary antibodies. Sometimes a bit fainter with ECL. 
 | 
| FH Maria (Verified Customer) (03-11-2021) | MTCO2 in treated Human Primary Fibroblasts. 10 ug of total protein. 12% gel. 1:1000 primary ab in BSA 3% in PBST O/N 4ºC incubation. Secondary ab HRP 1:5000 1h RT.
