羥基磷灰石樹脂,DNA級Bio-Gel HTP,100g價格_品牌:伯樂biorad 1588000 羥基磷灰石10G裝

美國伯樂BIO-RAD CHT陶瓷羥基磷灰石

CHT 陶瓷羥基磷灰石（原先稱為Macro–Prep 陶瓷羥基磷灰石）是一種球形、 巨孔的羥基磷灰石。它避免了晶體材料的局限性，可用于工業級層析柱。這種陶瓷材 料的分離方案與晶體羥基磷灰石的基本一致。CHT 既保留了晶體羥基磷灰石獨特的 分離特性，同時又可在高流速大型層析柱中反復使用，達數百循環。

I 型和II 型CHT 陶瓷羥基磷灰石具有晶體羥基磷灰石類似的洗脫特性，但同時也 有3個重要差異。I型的蛋白載量高，且對酸性蛋白載量更高。II型的蛋白載量較低， 對早期洗脫蛋白以及核酸的分辨率較佳。由于II型對白蛋白的親和力很低，它通常比I 型更適于純化多種類的免疫球蛋白。3 種顆粒大小20, 40 和80μm 能廣泛地用于分析 規模到制備規模的應用。
