LC3B Protein, Human, Recombinant (His Tag)

MAP1LC3B (Microtubule Associated Protein 1 Light Chain 3 beta, also known as LC3B) is a Protein Coding gene. The product of this gene is a subunit of neuronal microtubule-associated MAP1A and MAP1B proteins, which are involved in microtubule assembly and important for neurogenesis. LC3B is a member of the MAP1 LC3 family. It is most abundantly expressed in the heart, brain, skeletal muscle, and testis. LC3B is a subunit of the neuronal microtubule and functions in the formation of autophagosomal vacuoles (autophagosomes) . It is associated with MAP1A and MAP1B proteins, which are involved in microtubule assembly and important for neurogenesis. LC3B also plays a role in autophagy, a process that involves the bulk degradation of the cytoplasmic component.

At Leading Biology, the biological activity of a recombinant protein is routinely measured using a bioassay, e.g. chemotaxis or cell proliferation assay, enzyme assay, or a functional ELISA. When a recombinant protein is an enzyme, specific activity is derived from an enzymatic assay. Each enzyme is tested for potency by cleavage of a substrate. We are in the process of updating the biological activity data. If you have any questions regarding this update, please feel free to contact our technical support team.

Lyophilized from sterile PBS, 20% glycerol, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.

The recombinant human MAP1LC3B consists of 140 amino acids and predicts a molecular mass of 16.5 KDa. It migrates as an approximately 17 KDa band in SDS-PAGE under reducing conditions.

In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.
