| Abstract: | Electric precipitation is a method in serological diagnostics (determination of species-specificity). Since serum protein fractions (especially immunoglobulins) and extracts from blood stains migrate in agar-gel at pH 8.2--8.6 towards the cathode they cannot be used for the determination of the species specificity. By a chemical method using glutaraldehyde authors have produced an albumin-immunoglobulin complex, altering in this way the direction of electrophoretic mobility. Treatment of the blood samples with glutaraldehyde increases the sensitivity and realiability of the method. |
