Two new haemoglobins: haemoglobin Perspolis (alpha 64 (E13) Asp leads to Tyr) and haemoglobin J-Kurosh (alpha 19 (AB) Ala leads to Asp).

Two new haemoglobins are described which were found during a regular survey on voluntary blood donors in Iran. They are haemoglobin Perspolis [alpha 64 (E13) Asp leads to Tyr] and haemoglobin J-Kurosh [alpha 19 (AB) Ala leads to Asp]. The amino acid substitution in these two variants was determined by fingerprinting and amino acid analysis of the tryptic peptides and thermolytic peptides derived from abnormal tryptic peptides. Neither haemoglobin was associated with clinical symptoms.
