Abstract

An ultra-fast analysis of proteins, based on sodium dodecyl sulfate (SDS)-mediated gel electrophoresis was developed, in which protein molecular mass standards ranging from Mr 14 200 to 94 700 were separated within 3 min. A 50 μm diameter uncoated fused-silica capillary column and a high field strength are used. The effects of the SDS concentration in the separation gel buffer and in the sample buffer on the resolution of protein test mixture were studied. The influence of the heat treatment of the sample prior analysis is also discussed.
