Background Information
Cell-cycle progression gene 1 (CCPG1) is a receptor for ER stress-induced ER-phagy. CCPG1 localizes to perinuclear ER and in small foci at the ER periphery. It contains a LIR at the N-terminal cytosolic domain engaging LC3/GABARAP. (PMID: 29802216, PMID: 29290589)

Reviews
What customers say
Both reviewers used this antibody for Western Blot at a 1:1000 dilution and reported significant issues with nonspecific bands. One user (pancreas/liver tissue) observed multiple background bands between 40–70 kDa, rating it 3/5. The other (HCT116 cells) noted heavy background that made identifying the correct band difficult, ultimately requiring siRNA knock-down to confirm the ~98 kDa band as the true target, rating it 2/5. Overall, users experienced poor specificity with elevated background in their applications.
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
Zhe (Verified Customer) (09-12-2025) | There are several nonspecific bands showing up between 40-70kDa
|
H (Verified Customer) (04-05-2020) | This antibody has lots of background bands. In the beginning, I was not sure which band is the right band. In the end, I performed knock-down experiment using siRNA, and validated that the band close to 98 kDa is the CCPG1 band.
