Hemoglobin A1C, Human

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. Ultracentrifugal and osmotic pressure measurements indicate an actual molecular weight four times the minimum molecular weight. Source: Hemoglobin A1c from human erythrocytes. Applications: Suitable for use in ELISA. Other applications not tested, Recommended Dilutions: Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months after receipt at -20°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.
