a N-PAGE analysis for 6-HB formation by N36 and C34. The preincubated mixtures of the peptide N36 and berberine in phosphate-buffered saline (PBS) at the specified concentrations were added to C34, and then the peptides N36 or/and C34 with or without berberine were loaded into wells formed by combs in the gels. N36 and C34 served as negative controls, C34 + N36 served as a positive control. b The 6-HB structure formation by N36 and C34 was measured by Western blot using mAb NC-1
