Beads & Microspheres

MAB40 is part of BBI's anti-Biotin Gold Conjugate family which include anti-Biotin antibodies or streptavidin conjugated to BBI gold nanoparticles for use in the detection of biotinylated markers. Monoclonal anti-Biotin (MAB) conjugated to 40nm colloidal gold nanoparticles can be produced in large volumes of up to 24L OD10 per batch. The antibody is a high quality monoclonal antibody produced in mouse ascites and protein G purified to give a purity of greater than 90%. It is passively coupled to citrate capped gold nanoparticles and blocked with bovine serum albumin (BSA) For customers moving away from ELISA to lateral flow, biotinylated antibodies will generate gold labelled antibody conjugates in one simple step. Generally, biotin attaches to the Fc part of the antibody, leaving the variable part free to react with the antigen and form a fully active conjugate. Suitable for use in lateral flow devices. It can utilised in a range of matrices including whole blood, serum, urine, saliva

MagnaLINK Streptavidin Magnetic Beads (2.8 µm), 1 mL, offer the highest biotin binding capacity on the market. Higher binding translates to reduced bead mass required to immobilize a biotinylated sample & lower background from non-specific binding, resulting in better signals & lower costs. Beads are 2.8 μm diameter, super-paramagnetic, hydrophilic polymer–encapsulated, monodispersed microspheres with an exceptionally uniform size distribution (<5% CV) and fast (<2 min) magnetic response time.

Streptavidin Agarose Ultra Performance, 2 mL, provides high biotin binding capacity at a low price and enables improved recovery of any biotinylated biomolecule with lower non-specific binding. The combination of high-activity streptavidin and uniform 35-micron, 6% highly crosslinked agarose provides a biotin binding capacity of >330 nmol/mL of resin—the highest binding capacity in the industry. The base agarose beads support high flow rates and backpressures, which is ideal for automation.
