Weitere Untersuchungen an einem kristallisierten humanen Immunglobulin von monoklonalem Ursprung

摘要

An immunoglobulin („Goe”), previously believed to be homogeneous, was resolved into five bands by disc electrophoresis. Preparative isolation of the five fractions is described, and possible causes of heterogeneity discussed. It is shown that a major fraction could be crystallized; the crystals were not suitable for a single-crystal X-ray structural st
