Abstract
Novel biotinylated nucleotides have a chemically cleavable linker arm between a biotin and an organic basic group. They are useful in a method of isolating target macromolecules from crude physiological mixtures. The biotinylated nucleotides are bound via their organic basic groups to macromolecules having an affinity for the target macromolecules and brought into contact with the target macromolecules to form a biotinylated nucleotide-affinity macromolecule - target macromolecule complex. The complex thus obtained is brought into contact with immobilized avidin whereupon the biotin moeity binds to the avidin. The complex and avidin are washed to remove undesired substances and then the chemically cleavable bond in the nucleotide is cleaved to obtain the affinity-macromolecule - target macromolecule complex from which the target macromolecule can be obtained.
