Low Protein Adsorption Products and ELISA Related Products


PROTEOSAVE™ is a product that blocks nonspecific adsorption of protein, peptide to the inside of a plastic container by the coating of ultra hydrophilic polymer that S-BIO has newly and originally developed.


Reduce the adsorption of proteins, peptides and cells

The unique surface hydroxide group is coating and decreasing the loss of protein sample by preventing non-specific adsorption of protein and peptide.

Improved organic solvents resistance and heat resistance

PROTEOSAVE™ is stable against general used organic solvents, detergents and heating below 100°C.
