BLOCK ACEBlock Ace is designed as a highperformanceblocking reagent for use in immunological assays such as ELISA andWestern blotting. It may also be used for dilution of antibodies and for washing procedures in the above assays.Block Ace has been shown to have superior performance to 1% BSA in blocking in ELISA assays. In comparison toBSA, Block Ace provides reduced backgrounds and sharper standard curves.For blocking in ELISA applications, we recommend using a 1/4 dilution of the reconstituted solution.For blocking in Western Blotting applications, we recommend using the reconstituted solution neat.For washing applications we recommend a 1/10 dilution of the reconstituted solution, and adding Tween 20 to a levelof 0.050.2%v/v.For use as a test sample or secondary antibody diluent we recommend a 1/10 dilution of the reconstituted solution.
