Capillary electrophoresis with a polyacrylamide-coated capillary was u
sed for the separation of proteins, and the study of protein-small mol
ecule and protein-DNA interactions. The coating (10% T polyacrylamide)
is of sufficient thickness and hydrophilicity to reduce protein adsor
ption and eliminate electroosmotic flow. Data on the effect of sample
solvent constituents on the peak shape and position of protein solutes
was investigated. The results show that CE is a relevant and fast tec
hnique for the study of protein-DNA and protein-drug interaction. Also
, the addition of TRIS-buffer to the sample solution resulted in the C
E focusing of some basic proteins, while others were not affected.
