PAE μSphere™层析基材简介
μSphere™微球是与Source相同的层析填料基材,是集高流速、高载量、高分辨率(3H)于一体的新一代蛋白纯化填料的基础材料。过去二十多年来,聚合物微球得到了极大发展并成功应用于生物物质分离和纯化。PAE开发的聚合物微球,简写μSphere™是用聚丙烯酸酯制备的层析介质,传统的多糖基基材虽生物相容性好,但其骨架刚性低,在较高的压力下容易出现变形或者孔道的改变,影响纯化效率。μSphere™有效解决了琼脂糖骨架刚性低的问题。
PAE生产的用于生物大分子分离的微球为多孔的,有多种粒径和孔径,可达1000A,根须需求接上-OH,-COOH或-NH2 等基团,一边方便偶联其它配体或配基。
预装柱均可直接与GE、Waters、Agilent等公司的HPLC,如Akta等直连。经转接可连接BioRad公司的层析系统。
产品特点Features:
1. IMAC-μSphere是pae研发的用于金属螯合层析纯化带有2价金属离子结合位点的蛋白的填料,适用于所有带有金属离子结合位点的蛋白,包括但不限于His标签蛋白、BSA等。本产品以未加金属离子的形式提供,用户可以根据需要选择适用的金属离子,如Cu、Ni、Co、Zin等。
2. 尺寸和接口与GE HiTrap系列一致,无死体积。
3. 直连GE、waters、Agilent等公司的HPLC等设备,如lAkta、Prime、Avant等,使用方便,快捷。
4.柱体由生物兼容性良好的聚丙烯精工制作,耐压性高0.75Mpa
This Product is a prepacked column prepared with a column identical to HiTrap from GE, and can be directly linked to Akta and other chromatography equipments, conveniently and fast.
This product is filled with the new generation of polymer mono-dispersed microsphere developed by pae. This new material provides the matrix 3 H features, i.e, High flow rate, High dynamic binding capacity and High performance. All these are very important for chromatography.
本产品的载量远高于GE同类产品。因此,其洗脱条件可能与GE或其他公司的产品有所不同,可能需要更多的咪唑。方法主要有以下几点:① 增大洗脱体积;②提高咪唑浓度;③优化洗脱pH。
About HiTalon预装柱
HiTalon是Ppae为其1ml和5ml预装柱命名的商标。该商标下的所有预装柱均可直接与GE、Waters、Agilent等公司的HPLC,如Akta等直连。经转接可连接BioRad公司的层析系统。
产品描述:
HiTalon预装柱有1ml和5ml两种规格。柱体由生物兼容性良好的聚丙烯精工制造,耐压性高至0.75 Mpa。
两个规格的接口一致,可以单独使用,也可以串联或并联使用。可以用AKTA工作,也可以与其他层析系统匹配,甚至可以用注射器、蠕动泵或其他方式工作。
每套柱子均包含柱体和若干连接部件和封堵部件,以便与层析系统相连以及使用后密封保存。
IMAC μSphere 6
IMAC μSphere 6 cess IMAC medium, designed for purifying proteins and peptides that have an affinity for metal ions, such as histidine-tagged proteins but also untagged recombinant or native proteins
l Uncharged IMAC resin allowing possibility to charge with your metal ion of choice for optimized selectivity
l Convenient purification of histidine-tagged proteins, also when Ni2+ is not the best choice of metal ion
l As BioProcess medium it fulfills industrial demands for security of supply, robust performance and regulatory support.
l Available in the convenient and time-saving prepacked HiTrap and HiPrep formats.
IMAC μSphere 6 is a member of the range of IMAC chromatography media for capture and intermediate purification.
IMAC μSphere 6 is composed of highly cross-linked beads modified with a novel chelating ligand immobilized to the base matrix. IMAC μSphere 6 is supplied free of metal ions, allowing the user to charge it with the most appropriate metal ion for purification of a target protein.
The coupling chemistry and the novel ligand is designed to give minimal ligand leakage while providing high capacity.
IMAC μSphere 6 is available in a range of different bulk pack sizes and convenient pre-packed formats for easy scale-up and process development.
As member of the BioProcess media range, IMAC μSphere 6 meets industrial demands with security of supply and comprehensive technical and regulatory support.
