Methods for staining of ultramicroenzymelectrophoregrams are described. Sharp and well reproducible bands of isozymes of LDH, MDH, G-6-PD, AcP, AlP, alpha-NAE were obtained from homogenates of cultivated human fibroblasts, of rat's liver, kidney and brain, of human embryonic liver, and in blood serum of man and frog. An extract from the rat brain containing only 3.4 ng of proteins or a quantity of 70-80 fibroblasts were sufficient for obtaining a well differentiated spectrum of LDH isozymes. The ultramicromethod significantly lowers the need in deficit reagents, reduces the cost and time of analysis. |
