- Purification of a new unknown protein that you isolated from tissue and Assume that you have reached the following data during the characterization; Gel filtration: Gel filtration in protein native conformation When chromatographed, it has a molecular weight of 240000 daltons (240 kDa) is detected to be around. Gel filtration: The same protein is first denatured with 6 M guanidinium hydrochloride subjected to gel filtration chromatography again under denatured conditions. is retained, and the only column from the column with a molecular weight of about 60000 daltons (60 kDa) a protein is obtained. SDS-PAGE: Protein finally SDS-PAGE in the presence of beta-mercaptoethanol (Sodium dodecyl-sulphate polyacrylamide gel electrophoresis) analysis being held. As a result of SDS-PAGE analysis, their weight in the gel is approximately 40000 daltons. Two protein bands corresponding to (40 kDa) and 20000 daltons (20 kDa) is observed. In the light of these findings, the quaternary/quaternary…Modified TRUE or FALSE. Write the word TRUE if the statement is correct.
