Crompton Y1 - 1961/03/01 UR - http://jcp.bmj.com/content/14/2/164.abstract N2 - A quantitative paper electrophoresis method for the separation of haemoglobins A and A2 is described. The possible sources of error and the accuracy of the method have been investigated. The normal range for haemoglobin A2 by this method is 1·3% to 4·3% of the total haemoglobin concentration. Good clinical correlation has so far been obtained. ER -
