15712933-9	2004	Through this two-step chromatographic purification process, the obtained NGF was proved to be homogeneous on sodium-dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) and its relative molecular mass was estimated to be approximately 29 000, which was consistent with that reported in literature.	Sodium Dodecyl Sulfate	109-132	nerve growth factor	Gallus gallus	73-76
