Figure 3. SDS page image showing specific binding of cell protein to ganoderic acid DM (1) fixed with magnetic beads.
(A) Diagrams for ganoderic acid DM (1) fixation to the magnetic beads by reaction and amidation of the carboxylic group in the side chain of 1. (B) Lane 1: protein marker; lane 2: cytosolic protein incubated with FG beads; lane 3: cytosolic protein incubated with 1 (0.4 mM) bound FG beads; lane 4: cytosolic protein incubated with 1 (2 mM) bound FG beads; lane 5: cytosolic protein incubated with 1 (10 mM) bound FG beads. A specific binding protein of 46–58 kDa emerges with increased concentration of 1.
