For immunological tests

Blockmaster™ CE series

Covalent coupling type blocking agent

Blockmaster™ CE series, the unique water-soluble polymer proposed by JSR, has the end functional group that can covalently conjugate with the amino group on solid state. By supressing the unspecific adsorption of protein, the ligands become easier to be activated, and therefore higher signal-to-noise-ratio can be achieved. It can be used to replace BSA or used with BSA.

Blockmaster™ DB series

Synethetic blocking agent for latex particle

Blockmaster™ DB1130 is developed as surface blocking agents of latex particles. It can well suppress the unspecific binding of latex to enhance the stabiliy of colloid. The unique water-soluble polymer with the proper balalnce of hydrophobic unit and hydrophilic unit proposed by JSR can be used as a replacement of BSA.

Blocking agents for multiple purpose

Blockmaster™ PA series

Fully synthetic physical adsorption type blocking agent

Blockmaster™ PA series is a physical adsorption type blocking agent which is fully chemical synthetic and can be used in a wide variety of applications. The unique water-soluble polymer with the proper balalnce of hydrophobic unit and hydrophilic unit proposed by JSR can prevent the adsorption of proteins or cells for microplate or petri dish made with different material.
