3.4.21.74 40 - heating the RVBCMP at 40°C for 60 min at pH 7.4 does not influence the coagulant activity of the protein, whereas heating RVBCMP at 55°C for 20 min over a pH range from 7.0 to 8.0 results in only 42% of the original clotting activity remaining. Heating the RVBCP at 60°C results in a complete loss of coagulant activity 701326 3.4.21.74 75 - 30 min, stable, isozyme A3 29680 3.4.21.74 85 - 30 min, stable, isozymes A1 and 2 29680 3.4.21.74 100 - 1 h, in glycerol, stable 29682
