1.可從粗樣品直接純化目標(biāo)蛋白,極大的縮短純化時(shí)間
2. 可輕松實(shí)現(xiàn)對(duì)目標(biāo)蛋白濃度和體積的控制
- 通過調(diào)節(jié)洗脫緩沖液體積的方式,實(shí)現(xiàn)對(duì)目標(biāo)蛋白濃度和體積的控制,無蛋白損失,且不存在蛋白變性、沉淀的風(fēng)險(xiǎn)。
3. 一步純化即可獲得高純度目標(biāo)蛋白
海貍磁珠與市場上進(jìn)口產(chǎn)品相比,一步純化即得到同水平高純度的目標(biāo)蛋白。一個(gè)完整的操作流程即可獲得純度可以達(dá)到95%以上的目標(biāo)蛋白。 |
4.平行操作穩(wěn)定性高,可方便實(shí)現(xiàn)高通量和大規(guī)模蛋白純化
- 目的蛋白純度和產(chǎn)量的標(biāo)準(zhǔn)差均<5%。
- *不存在流速和樣品體積的限制,適用于高通量和大規(guī)模蛋白純化。
5.可以獲得較高的目標(biāo)蛋白產(chǎn)率
- 利用海貍磁珠對(duì)粗樣品進(jìn)行純化,一步完整的純化流程之后,90%以上純度的目標(biāo)蛋白,其產(chǎn)率一般達(dá)到70~80%。
6.可重復(fù)使用,再生工藝簡單
- 由圖A、B可知,海貍磁珠反復(fù)進(jìn)行多達(dá)六次再生處理,仍能保持較好的目標(biāo)蛋白結(jié)合能力和純度。

7. 鎳螯合磁珠與鈷螯合磁珠對(duì)不同分子量的His-tag蛋白純化對(duì)比
- ? Co離子螯合磁珠蛋白結(jié)合量比Ni離子螯合磁珠稍低,但純度更高;
- ? Co離子螯合磁珠洗滌和洗脫所用咪唑濃度都比Ni離子螯合磁珠低。
