Blot-Qualified BSA 10g W3841
Tween® 20 2.5ml 100% W3831
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.
