Background Information
Map1LC3, also known as LC3, is the human homolog of yeast Atg8 and is involved in the formation of autophagosomal vacuoles, called autophagosomes. Three human Map1LC3 isoforms, MAP1LC3A, MAP1LC3B, and MAP1LC3C, undergo post-translational modifications during autophagy. And they differ in their post-translation modifications during autophagy. Map1LC3 also exists in two modified forms, an 18 kDa cytoplasmic form that was originally identified as a subunit of the microtubule-associated protein 1, and a 14-16 kDa form that is associated with the autophagosome membrane. This antibody can cross react with MAP1LC3A, MAP1LC3B, and MAP1LC3C.

Reviews
What customers say
Users overwhelmingly rate this LC3 antibody positively (avg ~4.3/5 across 13 reviews). It performs well in Western blot, IHC, and IF, producing clear LC3-I and LC3-II bands with minimal background. Several users note it outperforms competing LC3 antibodies from other companies. Common dilutions range from 1:500 to 1:2000 for WB. Tested successfully in diverse samples including HepG2, SH-SY5Y, HCT116, microglia, mouse liver, and zebrafish. One reviewer reported detecting only one LC3 form, but this is the sole negative feedback. Overall, it's regarded as a reliable, cost-effective choice for autophagy studies.
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
Jumm (Verified Customer) (12-11-2025) | Reliable LC3 antibody with clear autophagy-related bands in Western blots and good performance in IF/IHC. Strong signal and minimal background make it a solid choice for LC3/autophagy studies.
|
A (Verified Customer) (07-15-2025) | Used for caco2 cells and animal colon tissue
|
Aditya (Verified Customer) (11-01-2024) | great with ecl
|
David (Verified Customer) (01-02-2024) | Good antibody, single band at the predicted molecular weight, no background.
|
Hala (Verified Customer) (05-09-2023) | works very good in milk5%
 |
Hala (Verified Customer) (04-28-2023) | works very good with milk blocking
|
Zhihao (Verified Customer) (07-25-2022) | We could detect one form of LC3 in our cell samples, which should be two.
 |
S (Verified Customer) (12-31-2021) | I have tried three different LC3B antibodies from three different companies so far. This antibody is by far the best (cost efficient as well)
 |
YING (Verified Customer) (09-25-2021) | The antibody works very well. Distinguished LC3-I and LC3-II bands. An increase of LC3-II level in response to treatment with bafilomycin A.
 |
Eric (Verified Customer) (03-13-2021) | Worked very well. I was able to get the LC3A/B bands on western blot using a 12.5% gel and prominent bands on a 8% gel. IF imaging worked fairly well, I used 1:100 which was likely too low so I will repeat at higher but got signal nonetheless. This performed better than some of the other LC3 antibodies we tested.
 |
Elzbieta (Verified Customer) (09-23-2020) | The antibody works very nicely in WB. Clear signal, no aspecific bands. Our lab discarded other products and switched to this antibody.
|
An (Verified Customer) (09-17-2020) | Used for IHC on zebrafish cryosections of eyes. Worked well.
|
David (Verified Customer) (03-30-2020) | Very nice visualisation of LC3-I and LC3-II. Run on 20% gel and significant changes in response to treatment with bafilomycin A and concanamycin A.
