说明
分析说明
Arginine can have benefitial effects on peak shape and recovery of hydrophobic proteins when chromatographed by size exclusion chromatography. In this case, with protein standards that are not particularly hydrophobic, no dramatic affect is noted, as assessed by peak efficiency, peak widths, or peak retention.
