A Cellulose Acetate Membrane Technique for the Determination of Adenylate Kinase Types in Bloodstains

CODEN: JFSCAS

Abstract

The genetically determined isoenzyme blood group system of adenylate kinase (AK) has been demonstrated in lysates of human erythrocytes [1,2] and in bloodstains [3]. The technique employed was horizontal starch gel electrophoresis using either a discontinuous histidine-citrate [1], a phosphate [2], or a succinate [4] buffer system. Since then, electrophoresis on cellulose acetate membrane (CAM) has been introduced as a rapid technique for the determination of AK types in fresh lysates [5,6]. We decided to investigate the use of CAM for determining AK types in bloodstains. In preliminary tests with CAM, we found the discontinuous histidine-citrate buffer system [1,5] gave clear results with lysates, but unsatisfactory results with even fresh bloodstain material. The phosphate buffer [6,7] seemed more promising and this paper describes our evaluation and adaptation of the phosphate system for bloodstain samples.
