WebTwo capillary zone electrophoresis kits (Hb A2 and Hb A1c) were tested for confirmation and identification of hemoglobin variants. The capillary zone electrophoresis experiments were performed at pH 4.7 (Hb A1c kit) and 8.7 (Hb A2 kit) in a 24 cm uncoated fused silica capillary tube (25 μm I.D.). Normal hemoglobins and common hemoglobin variants, … WebObjectives. To report the finding of a novel double heterozygous hemoglobinopathy, the coinheritance of Hb Fontainebleau (α-chain variant) with HbD-Punjab (β-chain variant) discovered upon investigation of unexplained microcytosis in an infant.

Web4 dic 2024 · On cellulose acetate electrophoresis at an alkaline pH, Hbs S and D Punjab show the same electrophoretic mobility, but high-performance liquid chromatography (HPLC) and electrophoresis at an acidic pH separate these two Hbs from each other, with Hb D forming a somewhat higher proportion of total Hb than Hb S. Hb A 2 may be … WebHPLC from a patient with haemoglobin Lepore trait. The variant haemoglobin has a retention time in the A2 window. This rules out haemoglobins D-Punjab and G-Philadelphia, which are in the D-window. The variant haemoglobin is quantified at 12.2%. This is not beta thalassaemia trait as the Hb A2 fraction is so high in beta thalassaemia trait. WebThe findings were further confirmed by HPLC results and molecular genetic studies. The present study reports for the 1st time a rare hemoglobinopathy of double heterozygosity … is in time based on a book
