Hb Camperdown beta104(G6)Arg->Ser
         
CONTACT Central cavity
HEMATOLOGY Normal in the heterozygote
ELECTROPHORESIS Hb X and Hb A separate at alkaline pH; Hb X moves faster than Hb A; excellent separation by IEF; at acidic pH Hb X moves between Hb A and Hb F, close to Hb F
CHROMATOGRAPHY Hb X and Hb A separate by DEAE-Sephadex chromatography; the betaX and betaA chains separate by reversed phase HPLC; betaX elutes between betaA and alpha
STRUCTURE STUDIES Tryptic digestion; separation of peptides by fingerprinting; amino acid analysis; sequencing; S. aureus V8 protease treatment; reversed phase HPLC; mass spectrometry
DNA ANALYSES Not reported; presumed mutation AGG->AGC or AGT at codon 104
FUNCTION STUDIES Normal; decreased Bohr effect
STABILITY Slightly unstable
OCCURRENCE Found in members of a Maltese family living in Australia
OTHER INFORMATION Quantity in the heterozygote ~50%
