Winners Announced of Membrane Protein Extraction Campaign

Dr. Bankala Krishnarjuna’s team recently published an article titled “Detergent-free extraction, reconstitution and characterization of membrane-anchored cytochrome-b5 in native lipids” in Chemical Communications, introducing an improved method for membrane protein extraction without destabilizing protein structures (Chemical Communications, 2020). In this study, the researchers demonstrated the feasibility of a direct extraction of a B16 kDa cytochrome-b5 from E. coli using a synthetic styrene-co-maleic acid-ethanolamine (SMA-EA) polymer and reconstituting the cytochrome-b5 protein  in polymer nanodiscs along with native lipids from E. coli.

With the help of Dr. Bankala Krishnarjuna, MolecularCloud also initiated a reward-winning campaign for this specific topic "Membrane Protein Extraction", which attracted 63 participants and have been discussed by 24 users, 2 among which with the first perfect quiz score or the best comment have won the reward.
