title: Partition affinity ligand assay (PALA). A new approach to binding assays.
abstract: A two-phase partitioning technique was used to separate free from bound labelled ligand in a binding assay. Efficient separation was accomplished by modifying one of the reactants in such a way that it partitions preferentially to one of the two phases. The biospecific interactions between the lectin concanavalin A and various carbohydrates and glycoproteins were investigated in this model study.
