(Biotin-Capture) Avidin beads are useful carriers for biotinylated molecules, in various applications such as the construction of affinity columns or for conducting immuno-precipitations (IP). Biotin-Capture Beads contain modified Avidin that is immobilized on rigid, highly cross-linked beaded agarose possessing high chemical Stability. Modified Avidin provides a substantial improvement over native Avidin. The high affinity to biotin is maintained, while background problems are minimized due to chemical modification on the protein. The Biotin-Capture Beads has proven to be particularly useful in the isolation of antigens and nucleic acids by employing biotinylated antibodies, or nucleic acid probes respectively. Biotin-Capture Beads can be used in numerous additional affinity chromatography applications.
