Hemoglobin by molecules such as carbon monoxide (for example, from tobacco smoking, exhaust gas, and incomplete combustion in furnaces). CO competes with oxygen at the heme binding site. Hemoglobin's binding affinity for CO is 250 times greater than its affinity for oxygen, meaning that small amounts of CO dramatically reduce hemoglobin's ability to transport oxygen. Since carbon monoxide is a colorless, odorless and tasteless gas, and poses a potentially fatal threat, carbon monoxide detectors have become commercially available to warn of dangerous levels in residences. When hemoglobin combines with CO, it forms a very bright red compound called carboxyhemoglobin, which may
Hemoglobin electrophoresis according to those charges and the amount, hemoglobins move at different speeds in the gel whether in alkaline gel or acid gel.The hemoglobin electrophoresis is also known to be thalessemia screening, this also can be helpful for the patient who is frequently need of fresh blood transfusion. The patient needs blood transfusion because the body is unable to produce enough hemoglobin to satisfy the body's requirement.(See Migration Patterns). Electrophoresis is done by the use of cellulose acetate. After running electrophoresis at 150 to 200 volt, stain the cellulose acetate gel with Ponceau red. Thalassemia major Hb F level and Hb
