Clone Host Grade Applications Polyclonal Sheep Serum E

Hemoglobin is composed of one globin plus four hemes; heme consists of protoporphyrin IX and ferrous iron. The iron content of human hemoglobin is 0.338% (w/w) which gives a minimal molecular weight of 16,520; however, ultracentrifugal and osmotic pressure
measurements indicate an actual molecular weight four times the minimum molecular weight.
