詳細(xì)介紹
1. 收率高,純度高
Fig. 1: Over 20% more yield obtained with PureCube Ni-NTA Agarose. SDS-PAGE of GFP expressed in E. coli and purified in gravity columns with PureCube Ni-NTA Agarose and Ni-NTA resin from Competitor Q. 80 mg/mL protein yield was obtained with PureCube Ni-NTA Agarose (E1–E4, Cube) compared to 65 and 48 mg/mL, respectively, with the widely used alternative resins G and Q (E1–E4, Competitor G / Competitor Q).

2. *的DTT和EDTA穩(wěn)定性
Fig. 2: NTA is robust in the presence of reducing and chelating agents. GFP-His was purified on gravity columns containing PureCube Ni-NTA Agarose after exposing the resin for 1 h to 3 concentrations of DTT or EDTA. NTA exhibits a shallow decay rate in binding capacity.
PureCube Ni-NTA 瓊脂糖在DTT和EDTA存在下非常堅(jiān)實(shí),在穩(wěn)定性測(cè)試中,將 PureCube Ni-NTA 瓊脂糖置于DTT與EDTA濃度逐漸升高的環(huán)境中處理1小時(shí)。再用處理過的凝膠在重力層析柱中純化大腸桿菌表達(dá)的GFP-His,凝膠的蛋白結(jié)合能力因存在DTT與EDTA而下降,但是衰減率平緩,即使在1.5 mM EDTA,凝膠依然具有其結(jié)合能力的54%。

產(chǎn)品優(yōu)勢(shì):
1)德國(guó)制造,品質(zhì)與信譽(yù)的堅(jiān)實(shí)保障;
2)結(jié)合載量可高達(dá)80mg/mL,目前市面上非常高的結(jié)合能力;
3)更*的DTT和EDTA穩(wěn)定性和耐受性;
4)凝膠的多孔性和均勻粒徑,使蛋白與凝膠之間有很好地相互作用;
5)適合低壓環(huán)境下的純化過程(大規(guī)模純化制備或預(yù)裝柱均可使用);
6)為研發(fā)、生產(chǎn)降低成本;
7)適用于大腸桿菌和真核細(xì)胞的裂解液和上清液;
8)同時(shí)可裝載Co, Cu, Zn和其它金屬離子。
