Blocking Agents

This BSA (bovine serum albumin) has been tested and qualified for optimum performance in immunoblotting applications with alkaline phosphatase antibody conjugates. It is shown to be alkaline phosphatase-free.

Tween® 20 is a nonionic detergent used as a buffer component for immunoscreening in the ProtoBlot® Systems. In addition to blocking agents such as BSA, which saturate excess sites of antibody binding on membranes, this detergent acts in solution to dissociate nonspecific interactions with an antibody probe.
