73.在蛋白質膠體電泳實驗中，蛋白質樣品常加入界面活性劑SDS使蛋白質變性，因此可依據蛋白質分子量大小將蛋白質分開。小明發現其由田鼠肝臟細胞核萃取的蛋白樣品在電泳膠體中泳動很慢，比其預期分子量顯著的大很多，下列何者最可以解釋其所觀察到的結果？
(A) 該蛋白會型成多聚體(如雙體或四聚體)
(B) 該蛋白質與電泳膠體親合力較大
(C) 該蛋白質含有很多帶正電胺基酸可與 SDS 結合使其泳動明顯較預期慢
(D) 該蛋白質高度醣化使分子量變大
(E) 該蛋白質溶解度較差因此在膠體中泳動較慢
(A) 該蛋白會型成多聚體(如雙體或四聚體)
(B) 該蛋白質與電泳膠體親合力較大
(C) 該蛋白質含有很多帶正電胺基酸可與 SDS 結合使其泳動明顯較預期慢
(D) 該蛋白質高度醣化使分子量變大
(E) 該蛋白質溶解度較差因此在膠體中泳動較慢
