Pierce™ Avidin Agarose, Thermo Scientific
Supplier: Thermo Scientific
Thermo Scientific Pierce Avidin Agarose can be used in a variety of applications for the affinity purification of biotinylated macromolecules.
- Strong, nearly irreversible biotin:avidin interaction
- Approximate Binding Capacity>20 µg biotin/mL resin
In one variation, an antibody that has an affinity for a particular antigen is labeled with biotin. Cells containing the antigen are lysed, then incubated with the biotinylated antibody to form a typical antigen/antibody complex. To isolate the antigen, the crude mixture is passed through an immobilized avidin or streptavidin column, which will bind the complex. After appropriate washes, the antigen can then be eluted from the column with a pH 2.8 elution buffer. The biotinylated antibody is retained by the column.
