摘要：Standardized and reliable methods have been devised to assay preparations of the glutamic oxaloacetic transaminase from human erythrocytes by the CAS principle, i.e. , the unsaturation and saturation of the coenzyme (pyridoxal 5'-phosphate) of a Coenzyme-Apoenzyme System. This dual enzymic assay is effective to detect and measure human deficiencies of vitamin B6. A preferred procedure has been developed, particularly for individuals and for limited groups, but is also applicable to large groups. A simplified procedure, which emphasizes the statistical significance of difference between large groups was also developed. Lyophilized erythrocyte hemolysates appear stable for up to 7 days for simplified transportation.
