In the blocking step, hydrophobic moieties causing “stickiness” in the specimen surface are rendered hydrophilic to minimize background. Nevertheless, the more dynamic charge-based interaction between the specimen surface and immunoreagents also needs to be controlled in order to eliminate background.
Aurion has developed BSA-c™ , a unique incubation buffer additive with an unparalleled ability to effectively prevent charge based background. BSA-c™ is prepared by acetylation of bovine serum albumin (BSA). Polycationic sites in the specimen interact readily with negatively charged acetylated BSA molecules. This significantly reduces the risk that such sites might bind negatively-charged immunoreagents and immunogold conjugates and thus reduces the risk of background. Read more about AURION BSA-c
