Asymmetric hybrids between hemoglobin Alberta (alpha 2 beta 2 101 Glu replaced by Gly) and hemoglobins A, A2 or F1 in different liganded states.

Isoelectric focusing in cylindrical polyacrylamide gels has been used to demonstrate the formation of asymmetric hybrids between an abnormal hemoglobin, Hb Alberta (alpha 2 beta 2 101 Glu replaced by Gly), and Hb A (alpha 2 beta 2), Hb A2 (alpha 2 delta 2) or Hb F1 (alpha 2 gamma 2 Acetyl). There was no discernible difference in the stabilities of the three hybrids (alpha 2 beta A beta Alberta, alpha 2 delta beta Alberta and alpha 2 gamma Acetyl beta Alberta) in the oxy, carboxy or cyanmet hemoglobin forms. Two mixed liganded hybrids, (alpha beta A)oxy (alpha beta Alberta)cyanmet and (alpha beta A)cyanmet (alpha beta Alberta)oxy were also demonstrated and found to have stabilities similar to that of the Hb Alberta hybrids.
