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 the antibody at 1:1000 dilution for Western Blot. One tested it on pancreas and liver tissue and reported several nonspecific bands between 40–70 kDa. The other tested it on HCT116 cells and noted significant background bands, initially making it difficult to identify the correct target band. They ultimately confirmed the ~98 kDa band as CCPG1 through siRNA knock-down validation. Overall, users found the antibody functional but flagged issues with nonspecific binding and background, suggesting optimization of conditions may be needed for cleaner results.
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.
