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. Solubility (Color) @10mg/ml: Dark red brown Iron (Fe): 0.25-0.35% Water (Karl Fischer): 8% 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. Country of Origin: USA Source: Porcine blood Form Important Note: This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications without the expressed written authorization of United States Biological. |
