ÎҲο¼µÄÎÄÏ׵ķ½·¨ÊÇthe trace amount of PEG-bis-folate may be removed by anion-ex-change chromatography on a DEAE-trisacryl Sepharose column. Folate-PEG-amine can be easily eluted with 10mM NH4HCO 3 (pH 8.0). The product folate-PEG-NH 2 was then lyophilized and analyzed for folate content by absorbance at 363 nm and -NH 2 content by the ninhydrin assay. The ratio of folate to free -NH 2 groups in this product was --~ 1 ÎÄÏ×Àï±ßÌáµ½ÁËÒ»¸öÀë×Ó½»»»Ê÷Ö¬£¬ÎÒûÓÐ×ö¹ýÀë×Ó½»»»Ê÷Ö¬µÄÇóÄÄλ×ö¹ýµÄ´óÉñ˵һÏÂanion-ex-change chromatography on a DEAE-trisacryl SepharoseÕâÊÇʲôÊ÷Ö¬¿ÉÒÔÔÚÄÇÂòµ½£¬¾ßÌå²Ù×÷ÊÇʲô°¡£¬Íò·Ö¸Ðл |
