Enhanced recovery of low concentration protein and peptide solutions on ultra-low binding microplates

摘要

SiO2 Medical Products (SIO) developed PureWARE™ Ultra-Low Binding (ULB) plasma-treated microplates with the combined benefits of enhanced protein recovery and reduced extractables. This study demonstrates enhanced protein recoveries, but at ten-times lower protein concentration, or 0.1 nM, compared with a prior study. In addition, no significant effect on enhanced protein recovery of plasma-treated microplates was observed in a long-term stability study carried out for 26 months under ambient storage conditions. Furthermore, recovery of three different peptide solutions, in the concentration range of 1.5–12 nM, was also shown to be enhanced on plasma-treated microplates relative to standard polypropylene microplates.
