Abrégé
Adding enough organic solvent to hydrophobic interactive chromatography elution buffer eliminates the need to also add detergent to the buffer when separating poly-peptides. For example, adding about 50% acetonitrile to detergent-free elution buffer enaibls one to separate full-length human growth hormone from its various truncated forms, to obtain hGH with a purity of >99.5%. This technique is useful to purify polypeptide where detergent to contamination in the resulting polypeptide is undesirable.
