Human erythrocyte lysate proteins were resolved into over 250 discrete spots by two-dimensional electrophoresis using isoelectric focusing in the first dimension and electrophoresis in the presence of sodium dodecyl sulfate, (SDS) in the second. The overwhelming excess of hemoglobin has made such analyses difficult in the past. However, with the ISO-DALT two-dimensional electrophoresis system, large numbers of red cell proteins can be mapped in the presence of hemoglobin. When hemoglobin and several other major proteins are removed by adsorption to DEAE-cellulose, additional minor components are seen, giving a total of over 275. With the use of purified preparations, the map positions of five cell enzymes or their subunits were determined: pyruvate kinase, catalase, glucose-6-phosphate dehydrogenase, hypoxanthine phosphoribosyltransferase, and carbonic anhydrase. The mapping techniques described complement and extend those traditionally used to find human red cell protein variants.

In a patient with paroxysmal nocturnal haemoglobinuria (PNH) enzymatic activities of erythrocytes and leucocytes were studied. Studies of autohaemolysis were also performed. The following erythrocytary enzymes were measured: Glucose-6-phosphate dehydrogenase (G-6-PD), pyruvate kinase (PK), glutathione reductase (GR), and acetylcholinesterase (AcChE). The following enzymes were measured in leucocytes: Adenosine deaminase, purine nucleoside phosphorylase, adenine phosphoribosyltransferase, hypoxanthine phosphoribosyltransferase and adenosine kinase. Normal activity of G-6-PD, GR and PK in erythrocytes was found. In leucocytes and lymphocytes activity of purine nucleoside phosphorylase was reduced. Auto-haemolysis in vitro was increased, which could not be compensated by addition of glucose or ATP.

The synteny of human mannose phosphate isomerase and pyruvate kinase and the assignment of the genes for these two enzymes to chromosome 15 were confirmed by analysis of 43 independently derived human-mouse hybrid clones. Hybrids between mouse cells deficient in hypoxanthine-guanine phosphoribosyltransferase and human fibroblasts carrying an X/15 chromosome translocation were also included in this study.
