Background Information
Intraflagellar transport (IFT), mediated by molecular motors and IFT particles, is an important transport process that occurs in the cilium. IFT particles are multi-subunit complexes that are made up of complex A and complex B. IFT20 is a component of IFT complex B and involved in ciliary process assembly. It is associated with the Golgi complex and plays a role in the trafficking of ciliary membrane proteins from the Golgi complex to the cilium.

Reviews
What customers say
Overall, users report good performance for immunofluorescence and Western blot. Three out of four reviewers rated it 5 stars, highlighting strong specificity, low background, and reliable Golgi/cilia labeling under PFA and cold methanol fixation. Recommended dilutions range from 1:150 to 1:1000 depending on the application. One reviewer (3 stars) noted a dotty, somewhat high background in a cilia-focused IF protocol on LIGHT2 cells, suggesting conditions may need optimization. In summary, the antibody is generally well-received for IF and WB, with most users achieving clear results, though one case indicated potential background issues in specific cell contexts.
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
Lola (Verified Customer) (10-23-2025) | This antibody shows good specificity and low background. Suitable for immunofluorescence and expansion microscopy. It works with PFA and cold MeOH fixation.

Charlotte (Verified Customer) (07-18-2024) | I did the standard iF protocol on the classic LIGHT2 cells used to study Hh signalling that depends on the primary cilia: PFA 4% 10 min cold methanol 5 min 1h in 1% BSA in PBST 1/150 in blocking solution, O.N. at 4°C 5*5min PBST 1/500 in blocking solution, 1h at RT° 4*5min PBST + 5min PBS I'm not convinced as the background is super dotty and quite important. Maybe the conditions must be optimized but it doesn't look promising

kes (Verified Customer) (01-17-2022) | I used it for WB(1:1000) and IF for cilia (1:200) and got good results.

Boyan (Verified Customer) (03-15-2019) | Excellent for IF labelling of the Golgi under PFA fixation.
