WebAn affinity chromatography column was developed through the coupling of a modified knob ‘A’ mimic peptide, ... The average fgn elution yield in these tests, which used fgn at fairly low concentrations (1 mg at 0.17 mg/mL) was 54 ± 4%, which is comparable to, if not better than other precipitation and affinity-based approaches. ... WebIn addition to resolution, another important factor in chromatography is the amount of time needed to elute a pair of solutes, which we can approximate using the retention time for solute B.

WebIn terms of chromatography, this is the ability to separate two peaks. Resolution, R, is given by where tr1 and tr2 and w1 and w2 are the times and widths, respectively, of the two immediately adjacent peaks. If the peaks are sufficiently close, which is the pertinent problem, w is nearly the same for both peaks and resolution may be expressed as. WebOct 16, 2013 · High-speed counter-current chromatography (HSCCC) was applied for the first time for the preparative separation of spirobisnaphthalenes from a crude extract of the endophytic fungus Berkleasmium sp.
