WebNov 22, 2024 · Protein purification by the detergent gradient. The bacterial cultures were grown similarly as mentioned above. The bacterial pellets from 250 ml of the culture were suspended in 45 ml of lysis buffer (50 mM Tris-HCl, pH 7.4, 150 mM NaCl, 2 mM dithiothreitol [DTT], 1% Triton-X100, 5mM CHAPS, 0.1 mM phenyl methyl sulfonyl … WebExtraction of the membrane proteins from the lipid bilayer is facilitated by detergents. The detergent makes the proteins partially soluble in the buffer by making a protein: detergent complex. However, the more the stringency of the detergent, higher is the probability of irreversible protein denaturation. Therefore, by rule, it is suggested ...
