Hemoglobin Powder, Porcine (Powder)
Storage 4°C Shipping Blue Ice
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.

Storage and Stability:
Lyophilized powder may be stored at 4°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
Note: Since native hemoglobin is readily oxidized in air, these preparations may be predominantly methemoglobin. Opened bottles should be capped tightly and kept in a dark, low humidity environment.
