Adsorption of Cationic Peptides to Solid Surfaces of Glass and Plastic
Fig 4
Peptide loss during 1 h incubation of 2 mL 2 μ M solutions in sample containers.
The percentage of recovered peptide was measured for mastoparan X, melittin, and magainin 2 solutions in borosilicate glass vials, polypropylene tubes, Protein LoBind tubes, or quartz glass cuvettes. The data are the average of two separate experiments. The error bars show the standard deviations. The data demonstrate that peptide surface adsorption is not just a phenomenon that occurs at high surface area-to-solution volume ratios.
