How many globin chains in hemoglobin
WebSickle cell anemia results from the single amino acid substitution of valine for glutamic acid in the beta-chain owing to a nucleotide defect that causes the production of abnormal beta-chains in hemoglobin S. Abnormal hemoglobin chains form polymers in the deoxygenated state, leading to the charact … WebSeparation and purification of globin-chains To separate α-type and β-type globin-chains, the S-pyridylethy-lated hemoglobin was subjected to a Resource column and eluted with a 0.1% TFA buffered gradient to 60% acetonitrile in 0.08% TFA. All fractions were monitored at 214 and 280 nm by a spectrophotom-eter (Model 116, Gilson).
