(a) SDS-PAGE analysis of the time course from the protein ligation reaction of nSH3 and cSH3 in the presence of 0.5 mM TCEP. Lane 1, 0 min after the mixing; lane 2, 3 min; lane 3, 10 min; lane 4, 30 min; lane 5, 1 hour; lane 6, 3 hours; lane 7, 22 hours. (b) Kinetic analysis of the protein ligation from the SDS-PAGE.
