[Solved]: Thuse a purified solution of insulfin receptor

Thuse a purified solution of insulfin receptor. The fest time I do molecular eclusion using my surrole I get a single protein fraction that runs off the colume at a slae of approximately 160 kdal . If I add urea to my moble phant and nan the sumple acsin, I get a probein fraction of approximately 80icdal, Y I add beta mercaptoethangl and urea I ger two proteins fractions of 60Kdal and 20Kd.L What is FALSE of the imulin receptor. Ris a congles of four peptiales. A and C ant faise.
