Aqua Block Buffer is a non-mammalian blocking reagent supplied in PBS for immunoassays involving membrane or other solid phase material. This new reagent is optimized for superior performance in super sensitive assay systems, while utilizing proteins that do not interact with mammalian antibodies.

Numerous solutions containing proteins are used and recommended for blocking of excess binding sites in ELISA, Western Blotting, Immunohistochemistry and other immunochemical applications. Aqua Block Buffer utilizes proteins that do not interact substantially with mammalian antibodies and therefore will display little or no background.

How to Use:
1. Add the blocking solution to the ELISA wells, blotting membrane or immuhistochemical slide.
2. Incubate 30 minutes to 2 hours at either room temperature or 37°C.
3. Continue with other reagents after the blocking according to your own protocol.

NOTE: Using this blocker as a diluent with HRP conjugates may decrease your signal since this blocker contains sodium azide.

Purity: Whole antiserum
