(vi) 6-Phosphogluconate Dehydrogenase (PDG) E.C. 1.1.1.44 Buffers: Bridge: 0.1 M P0 4 buffer at pH 7.0 and 1.5mg of NADP was added to 75 ml of the cathodal compartment buffer. Gel: A 1 in 10 dilution of bridge buffer and starch to which 2.4ml of NADP was added just before degassing. (vii) Glutamate Oxaloacetate (GOT) E.C 2.6.1.1 Buffers: Bridge: 0.2M di-Sodium Hydrogen Phosphate! 0.03M Boric acid, pH 7,5 Gel: 1 in 10 dilution of bridge buffer 185
Appendix 9 Appendix (9a) Preparation of Agar for Overlay Agar Noble (Difco Labs., Detroit, USA) was prepared by dissolving 12g in one liter of distilled water, melted and allowed to cool to 37°C. Ten millilitre volumes were aliquoted in 50 ml bijou bottles and stored at -20°C until required. Appendix (9b) List of Electrophoresis Buffers and Their Preparation (1) 0.2 M Phosphate (P0 4 ) Buffer. 17.4g/L di-Sodium Hydrogen orthophosphate (Polychem. Durban, SA.) 11.5g/L Sodium dihydrogen orthophosphate (BD H) pH 7.0 (2) 0.1 M Phosphate buffer was prepared similarly with the proportionate adjustments of quantities. (3) 0.1 M Tris maleate Buffer 12.14 g/L Tris (Polychem. Durban, SA.) 11.16g/L Maleic acid (Saarchem. Krugersdorp, SA) 2.03 g/L Magnesium Chloride (Saarchem. SA.) 3.72g/L EDTA (Polychem, Durban, SA) The pH was adjusted to7, 4 with 10 M Sodium Hydroxide. 186
