According to the traditional immunization procedure, after the first injection of the sample A (emulsion of aimed antigen and Freund's complete adjuvant) to immunize rabbit, successive injections of the sample B (emulsion of aimed antigen and Freund's incomplete adjuvant) were followed every 2-4 weeks. In general, high titer of the corresponding polyclonal antisera will be observed after 4-5 injections of sample B in 3-4 months. This report presents a simply modified procedure that was able to stimulate the antisera formation in one month and achieve enough avidity to satisfy either Western blot or immunohistochemistry analysis. It just applied an additional injection of the sample A to the rabbit at the 3rd day after the primary immunization injection. You could gain the high titer of the antisera right after the first sample B injection in one month. This method has produced the desired results in three different recombinant antigens with different molecular weight (5.9 KD-55 KD) expressed from prokaryotic or eukaryotic cells.
