We DO think that our NanoLink™ streptavidin-coated beads might provide you with lower nonspecific protein binding to your biotinylated biomolecule (compared to competing products) for 2 reasons. (1) Because of the highly crosslinked streptavidin (using our unique, patented chemistry) there is less polymer surface area on the bead exposed for proteins or nucleic acids to adhere to. This in itself should reduce NSB for you. Our extensively crossliked streptavidin is the reason the biotin binding capacity of these beads is so high. (2) And…because of the high biotin binding capacity, you can use FEWER beads in your assay…again reducing nonspecific protein binding.
