Background Information
LC3B, also named as MAP1LC3B, MAP1A/1BLC3, belongs to the MAP1 LC3 family. It is a subunit of neuronal microtubule-associated MAP1A and MAP1B proteins, which are involved in microtubule assembly and important for neurogenesis. In cell biology, autophagy, or autophagocytosis, is a catabolic process involving the degradation of a cell's own components through the lysosomalmachinery. It is a major mechanism by which a starving cell reallocates nutrients from unnecessary processes to more-essential processes. Two forms of LC3, called LC3-I (17-19kd) and -II(14-16kd), were produced post-translationally in various cells. LC3-I is cytosolic, whereas LC3-II is membrane bound. The precursor molecule is cleaved by APG4B/ATG4B to form the cytosolic form, LC3-I. This is activated by APG7L/ATG7, transferred to ATG3 and conjugated to phospholipid to form the membrane-bound form, LC3-II. The amount of LC3-II is correlated with the extent of autophagosome formation. LC3-II is the first mammalian protein identified that specifically associates with autophagosome membranes. MAP1LC3 has 3 isoforms MAP1LC3A, MAP1LC3B and MAP1LC3C. MAP1LC3A and MAP1LC3C are produced by the proteolytic cleavage after the conserved C-terminal Gly residue, like their rat counterpart, MAP1LC3B does not undergo C-terminal cleavage and exists in a single modified form. This antibody is specific to LC3B.

Reviews
What customers say
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
Jacob (Verified Customer) (07-23-2026) | Has a very strong non-specific banding pattern above 20kDa, so the LC3B was faint. 2*
 |
Alicia (Verified Customer) (09-30-2025) | Control microglia derived from iPSC with and without bafilomycin. Drug treated microglia derived from iPSC with and without bafilomycin.
 |
Allegra (Verified Customer) (09-30-2025) | Work for cell lysates only in concentration 1:500 and this is only slightly detectable. In extracellular vesicles nearly no signal.
|
Azita (Verified Customer) (06-02-2021) | Western blot analysis using LC3B-Specific Polyclonal antibody in NSC34 cell line at dilution of 1:300. Immunohistochemistry labelling of primary rat cortical neurons using LC3B-Specific Polyclonal antibody at dilution of 1:500 showed strong labelling.
