Protein containing solutions are commonly used in ELISA and other immunoassays to block excess binding sites and reduce nonspecific binding of secondary reagents. Bovine Serum Albumin (BSA) has long been the choice for many scientists attempting to reduce nonspecific binding in immunoassays. UltraBlockBSATM utilizes special chemistry to enhance the solubility and stabilize the BSA. UltraBlockBSATM readily blocks and excess reagent easily washes away providing ideal blocking without lingering residual protein that can interfere with optimal signal. An additional benefit of UltraBlockBSATM is that it provides a long term stabilizing environment for the antigen, or antibody coated on the ELISA plate. long been the choice for many scientists attempting to reduce nonspecific binding in immunoassays.

• Ease of Use – A one component “Ready Use” formulation increases assay efficiency.
• Extended Shelf Life – UltraBlockBSATM is stable for a minimum of 2 years when stored at 2° 8°C.

UltraBlockBSATM is a ready to use solution that needs no preparation or dilution. Once you have coated your micro ELISA plate(s) with capture antibody or antigen, aspirate or dump out the coating solution and wash the plate 24 times. Pipette a volume greater than the coating solution volume, but not to exceed 350 µl of UltraBlockBSATM per well and let incubate for 2 – 3 hours in an incubator at 37°C.
