SeaBlock Fish Plasma — Improve Assay Performance without Cross-Reactivity

SeaBlock is Entirely BSE-Free!

EastCoast Bio’s exclusive SeaBlock fish plasma blocking reagents make an excellent alternative to bovine serum and help improve the overall performance of users’ assays.

In the past, the benefits of the blocking procedure in an assay were not well known. Now, however, scientists are becoming more aware that optimizing their blocking reagents may improve the overall performance of an assay. They also now understand that using bovine-derived proteins in their blocking reagents is not always the best choice because of cross-reactivity problems with mammalian-based antibodies.

SeaBlock fish plasma based products solve the cross-reactivity problem. Using fish plasma as an alternative to bovine serum is a way to get the benefits of blocking in users’ assays without the issues of cross-reactivity. These products function as universal blockers derived from non-mammalian vertebrates with an entirely different immune system.

Since SeaBlock products are derived entirely from fish, they are not subject to the recent European Union ban on all cattle products that could carry Bovine Spongiform Encephalopathy (BSE).
