PD MiniTrap G-10 columns are a member of the Trap platform, which addresses the need for flexible, small-scale preparation of proteins and peptides before analysis. Thermo Fisher Scientific, byPaul Haney, Ph.D.; Aaron McBride, M.S. Entrapment is evident upon comparison of recovery values for the PD-10 columns processed by centrifugation (spin) versus gravity-flow (drip); when a large volume of buffer is used to push a smaller sample through the column (as in the drip method), total protein recovery typically increased by 10 to 20%. Elution profiles for BSA using the gravity protocol are shown in Figure 4. The data in Tables 1 and 2 are more easily visualized and summarized by representing them as surface maps of protein recovery versus sample volume and sample concentration (Figure 2). Stars indicate columns that were tested in this study. For Research Use Only. 0000009396 00000 n MKK The specified ranges are the manufacturer-recommended sample volumes for spin protocols with each column. Efficiency of salt removal (desalting, per se) from 500mM NaCl to 25mM NaCl was determined by measuring the conductivity (mS/cm) of the starting and final samples compared to a standard curve. startxref 0000061381 00000 n 0000006896 00000 n Please change the country on your profile in order to switch to another country store.

Centrifuge for 5 min in a swinging bucket centrifuge at 1,000x g to remove the reaction buffer. 0000084591 00000 n . Nevertheless, our experiments with pure and complex protein mixtures in Tris-buffered saline, suggest that Zeba Spin Desalting Columns will perform as well or better than the GE Healthcare and Bio-Rad columns in typical applications with protein samples. ReadiUse Disposable PD-10 Desalting Columns contain Sephadex G-25 resin for rapid buffer exchange, desalting, and removal of small contaminants (e.g., salts, dyes, radioactive labels) from samples using gravity flow or centrifugation. If the column does not begin to flow, push the cap back into the column and remove it again to start the flow. How can you efficiently remove this top filter without disturbing the packed bed? Protein concentration was determined using the BCA Protein Assay Kit (Part No. Spin protocol 8 7. PD MiniTrap G-10 columns are prepacked, single-use gravity columns for buffer exchange and cleanup of biological samples, for example peptides, small proteins, and oligosaccharides. After it enters the packed bed completely, add another 1.0mL. 0000059295 00000 n 0000005855 00000 n 0000032058 00000 n Prepare samples in range of 1.0 to 2.5mL by gravity flow or 1.75 to 2.5mL by centrifugation.
