Sample Notes

Reversed phase runs of PEGylated ribonuclease A using different gradient conditions on a Jupiter 300 C4 column (gradient length 25 min). Note that if initial %B is increased much above 25% then retention and resolution of PEGylated forms is lost. Gradient slopes of between 1-2%/min appear to be a good compromise between resolution and run time.
