44 kDa

 

The molecular weight of horseradish peroxidase (HRP) is about 44 kDa. It includes the polypeptide chain hemin (33,890 Daltons), Ca2+ (about 700 Daltons), and carbohydrate (about 9,400 Daltons). At least seven isozymes of HRP exist. The isoelectric point for horseradish peroxidase isozymes ranges from 3.0 - 9.0.
