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.

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.
