Streptavidin Beads T3
APExBIO Streptavidin Beads T3 are ideal for numerous applications, including purification of proteins and nucleic acids, protein interaction studies, immunoprecipitation, immunoassays, phage display, biopanning, drug screening and cell isolation.
Add the beads to a sample containing biotinylated molecules, e.g. peptides, proteins, antibodies, sugars, lectins, oligonucleotides, DNA/RNA. During a short incubation, the biotinylated molecule will bind to the beads. The molecule-bead complex can be separated by using a magnet. capture, washing, and detection can be optimized for manual or automated use. With indirect capture, mix the biotinylated molecule with the sample to capture the molecule-target complex before adding the beads.
