Blocking Buffer 10X is recommended for use with the Matched Antibody Pair kits during ELISA development.  The Blocking Buffer 10X is a BSA based buffer (10 %w/v) that is designed to reduce background interference due to non-specific binding. 

The 10X Blocking Buffer should be diluted to 1X using 1X PBS before use.

See our website for a protocol.

The Blocking Buffer 10X is also avaialble as part of our Matched Antibody Pair Kit Accessory Pack (ab210905).
