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). WebHemoglobin is the protein that makes blood red. It is composed of four protein chains, two alpha chains and two beta chains, each with a ring-like heme group containing an iron atom. Oxygen binds reversibly to these iron atoms and is transported through blood.
