12 x 75 mm tubes are pre blocked with standard proteic blocking (ELISA Blocking) or with non proteic blocking (BlockerWell)
Recommended working volume of 100 to 500 μl
Packaging: 20 coated 12 x 75 mm tubes in a single barrier bag with desiccant.
Streptavidin HB coated surface offers a powerful and universal instrument for binding any biotinylated molecule (Proteins-Peptides-Polysaccharides-Oligonucleotides-DNA fragments-etc.) finding a special application for those molecules which do not offer reliable bonding by passive adsorption or adsorb in an unfavourable orientation. Unlike the normal streptavidin coated surface, this product is particulary useful in competitive tests to measure biotinylated low molecular weight molecules.
