Abstract:
:An automatic immunospecific affinity-chromatographic system for continuous operation is described. The system comprises time-controlled sample application, washing and elution steps and automatic dialysis of eluted fractions. The applicability of the system is illustrated by the purification of pregnancy zone protein on immunosorbent gel.
