A comparative study of immuno-blotting techniques for the detection of Gc-subtypes after isoelectric focusing on agarose and polyacrylamide gels

A comparison of separation and detection techniques has been carried out to determine the most suitable combination for use in Gc-subtyping. The best results (i.e., high sensitivity, distinct bands, especially with reference to the 1S and 1F separation) were achieved using isoelectric focusing in polyacrylamide gel (pH 4.5-5.4) followed by transfer to nitrocellulose membrane by electroblotting and finally detection with enzyme-linked antibody complex.
