CHEMICAL, CLINICAL, AND IMMUNOLOGICAL STUDIES ON THE PRODUCTS OF HUMAN PLASMA FRACTIONATION. XIII. THE SEPARATION AND CONCENTRATION OF ISOHEMAGGLUTININS FROM GROUP-SPECIFIC HUMAN PLASMA 12

Abstract
A specific, stable, and highly active isohemagglutinating material has been prepared as a by-product of the human serum albumin program. A conc. of isohemagglutinating activity over plasma of 16 times has been achieved. The speed and specificity of reaction, stability, reproducibility, subgroups specificity, and use of this material for blood grouping are described.
