Using gel filters instead of flushing water means less bacteria growth and less smell, he said.
In 2003, the Canadian photographer Marianna Rothen began experimenting with a Polaroid SX-70, using gel filters to amplify the camera's painterly effect.
Fraction A was first gel filtered on a Sephadex LH-20 column eluted with n-hexane/CH2Cl2/MeOH, 4 3 3 to give four pooled fractions (A1-A4).
The gel filters selected for the acquisition of VIVL images in this study have the advantage of being practical to use and affordable, however both have certain limitations.
The protein samples labelled with an excess of metal were treated with about tenfold excess of EDTA to 111In3+ or Eu3+ and then gel filtered to remove excess metal and preclude nonspecific binding of the metals to the protein.
After TEV cleavage, IgFLNb23-24 was gel filtered on Superdex200 10/300 column (GE healthcare).
The protein was then buffer exchanged, TEV cleaved and gel filtered as above.
The purified enzymes were concentrated by ultrafiltration, gel filtered using a PD-10 gel filtration column (GE Healthcare) equilibrated with 50 mM Tris, 1 mM EDTA, 2.5 mM DTT, pH 7.5 and stored at −70°C until used.
We compare popular sample protocols that are based on in gel, filter-aided and in solution digestion procedures.
After the incubation, the solution was gel filtered as described previously (Fronzes et al, 2009).
