Assay of glycosylated haemoglobin using agar electrophoresis

A fast electrophoretic method for measuring glycosylated haemoglobin (HbA1) is described. Eight samples per cell can be assayed in a single run. Results are compatible with those found by macro-column cation-exchange chromatography; precision is good. The practical short-comings of the commercially ready-made mini-column chromatographic procedures are not seen using this method.
