The Blockmaster™ series consists of several synthetic water soluble polymer blocking reagents that solve the safety, quality and purity issues often observed when using “standard” protein based blocking solutions.
Blockmaster™ CE510 and CE210 are fully synthetic, water soluble blocking reagents consisting of a hydrophilic PEG tail and multiple amine-end groups. While the PEG tail reduces the non-specific binding, the amine end-group allows for a covalent conjugation with amine reactive surfaces.

Blockmaster™ DB1130 is a fully synthetic, water soluble polymer blocking reagent consisting of both hydrophilic and hydrophobic units. The optimized combination of hydrophilic and hydrophobic units strongly reduces the non-specific binding and greatly enhances colloidal stability of latex and magnetic beads.
