General description

Microtubule-associated proteins 1A/1B light chain 3 or MAP1LC3 is a cellular protein that is involved in the formation of autophagosomes . MAP1LC3 genes have three known human isoforms, namely, MAP1LC3A, MAP1LC3B and MAP1LC3C. These isoforms have different responses to amino acid starvation and varied sub-cellular localization patterns . Anti-LC3A antibody reacts with human and rat LC3A-I (approx. 18 kDa) and LC3A-II (approx. 16 kDa) by immunoblotting and immunoprecipitation. The antibody is also specific for mouse LC3A-I (approx. 18 kDa). Specific cell treatment and/or long exposure may be required for the detection of mouse LC3A-II. The immunizing peptide specifically inhibits the detection of the LC3A bands by immunoblotting.

Specificity

Anti-LC3A antibody recognizes human and rat microtubule-associated protein light chain 3-A (LC3A-I) and LC3A-II by immunoblotting and immunoprecipitation (~18 kDa and ~16 kDa, respectively) and mouse LC3A-I (~18 kDa).

Immunogen

Synthetic peptide corresponding to amino acids of human LC3A isoform α, conjugated to KLH via C-terminal cysteine residue. The corresponding sequence is identical in rat and mouse.

Application

Anti-LC3A antibody produced in rabbit has been used in
  • immunohistochemistry
  • immunostaining
  • western blotting

Biochem/physiol Actions

Microtubule-associated protein light chain 3-I (LC3-I) is modified to a membrane-bound form, LC3-II (a LC3-phospholipid conjugate), by mammalian autophagy related 7 (Atg7) and Atg3, which are E1- and E2-like enzymes, respectively. The amount of LC3 II correlates with the extent of autophagosome formation. LC3A can also be as an autophagosomal marker.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Storage and Stability

For continuous use, store at 2-8 °C for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing, or storage in “frost-free” freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilutions should be discarded if not used within 12 hours.
