ELECTROPHORESIS		No separation reported
IEF		(Nearly) no separation
CHROMATOGRAPHY		No separation
CHAIN SEPARATION		AgammaT = ~15%; Ggamma = ~70%; AgammaI = ~15%
STRUCTURE STUDIES		Tryptic digestion of AE-gammaX chain; separation of peptides by fingerprinting or reversed phase HPLC; amino acid analysis; sequencing
DNA ANALYSES		An ATA->ACA mutation at codon 75
NOTES		Found at high frequencies in nearly all populations; quantity in heterozygotes ~15% of total Hb F
