TALON Spin Columns

SDS-PAGE of TALON CellThru Resin purified proteins

SDS-PAGE of TALON CellThru Resin purified proteins. E. coli BL21 cells were sonicated in TALON wash buffer and run through a TALON CellThru column eluted in 150 mM imidazole. Note that some target protein is trapped in membrane fractions and does not get absorbed on the column. M: molecular weight marker.

Native purification with TALON resin preserves biological activity of proteins

Native purification with TALON resin preserves biological activity of proteins. Fresh cells (0.5 g) expressing 6xHis-GFPuv were extracted in 5 ml of 50 mM sodium phosphate; 0.3 M NaCl, pH 7.0 Panel A. Elution profile of GFP which was loaded, washed with the same buffer, and eluted with a step gradient of imidazole (150 mM). Panel B. Fractions were analyzed by SDS-PAGE. The fluorescent signal of green fluorescent protein (GFPuv) was completely enriched by TALON Superflow Resin.

Purification of 6xHis-GFPuv under denaturing conditions using TALON resin

Purification of 6xHis-GFPuv under denaturing conditions using TALON resin. The fusion protein was purified in 8 M urea using TALON resin. M=molecular weight markers.

Native purification of 6xHis protein using TALON resin in the presence of beta-mercaptoethanol

Native purification of 6xHis protein using TALON resin in the presence of beta-mercaptoethanol. N-terminal 6xHis-tagged mouse DHFR (19.5 kDa) was expressed in E. coli. 2 ml of lysate was purified using gravity flow on TALON resin in increasing concentrations of beta-mercaptoethanol. Even lanes: 20 μl of nonadsorbed material. Odd lanes: 5 μl of eluate

Protein purification yields in the presence of beta-mercaptoethanol with TALON resin compared to Ni-NTA resin

Protein purification yields in the presence of beta-mercaptoethanol with TALON resin compared to Ni-NTA resin. N-terminal 6xHis DHFR was expressed and purified under native conditions. Protein concentrations were determined by Bradford assay. Yields are expressed as a percentage of total protein in the cell lysate.
