Hb F-Columbus-Ga or a2 Gγ2 94(FGJ)Asp→Asn |
|
| Abstract: | A new γ chain variant with an electrophoretic mobility at pH 8.1 between those of Hb S and Hb C was isolated and quantitated by DEAE-cellulose chromatography. It was readily identified with the use of various micro-chromatographic and sequencing procedures as α2Gγ2 94(FGl)Asp→Asn. The hemoglobin was named Hb F-Columbus-Ga. The quantity of this GY chain variant (as % total γ chain) was about 39% and the percentages of the normal Gγ and AγI chains were 37% and 24%, respectively. |
