HisTrap HP和HisTrap FF之间有什么差别吗?各自的优缺点?
楼层直达:
这个帖子发布于6年零67天前,其中的信息可能已发生改变或有所发展。
我准备要纯化His-tag重组蛋白,在HisTrap HP和HisTrap FF这两种预装柱的选择上,有点迷惑,请版主详细解释一下,多谢!
另外,想问问,这种预装柱大概能反复使用多少次?他们的配基是IDA还是NTA的?
不知道邀请谁?试试他们
分享到哪里?
Histrap的配基是新的配基,不同于较老的IDA和NTA,和NTA一样是4齿的,所以金属离子的稳定性很好,脱落少;但由于是新的配基,载量要比NTA和IDA高很多。
FF的粒径90u, HP粒径34u, 前者流速快,后者柱效高,但一般情况下用起来差别不大。
分享到哪里?
使用次数应该可以上百次,和样品以及维护有关。
样品越干净,及时清洗维护,寿命就会长一些。

产品详细信息
HisTrap& FF Columns - Easy Scale-up PurificationOptimized for scaling up purification of histidine-tagged* proteins.Convenient and time-saving 1-ml and 5-ml prepacked HiTrap formats.High binding capacity, approx. 40 mg/ml medium.Negligible leakage of Ni2+.Compatible with a wide range of reducing agents, detergents, denaturants, and other additives.Simple operation with a syringe, pump, or chromatography system such as &AKTAdesign. HisTrap FF columns are available in 1-ml and 5-ml column formats, prepacked with Ni Sepharose 6 Fast Flow for simple, one-step purification and scaling up purification of histidine-tagged proteins. Ni Sepharose 6 Fast Flow consists of 90-&m beads of highly cross-linked agarose, to which a chelating ligand has been immobilized. This chelating ligand is charged with Ni2+ ions, the first-choice metal ion for purifying most histidine-tagged proteins. The negligible leakage of Ni2+ ions from the matrix ensures reliable capture of histidine-tagged proteins in repeated IMAC purifications. &HisTrap FF 1-ml and 5-ml columns allow convenient and simple one-step purification of histidine-tagged proteins. &HisTrap& FF Columns - Easy Scale-up PurificationTechnical InformationThe high flow rates made possible by the Ni Sepharose 6 Fast Flow matrix make HisTrap FF columns ideal for small scale-up. Capacity can be increased by connecting columns in series. &HiTrap& IMAC FF, see IMAC Sepharose 6 Fast Flow Media/HiTrap IMAC FF Columns/HiPrep IMAC FF 16/10 Column/HiScreen IMAC FF Column, is the product of choice when charging the medium with different metal ions for optimization of purification protocols. &For the complete range of products for purification of histidine-tagged proteins, see Introduction to Tagged Protein Purification. &* For licensing information, see Legal Info. &TECHNICAL SPECIFICATIONSMedium&Ni Sepharose 6 Fast Flow&Column volume&1 ml and 5 ml&Dynamic binding capacity*&Approx. 40 mg histidine-tagged protein/ml medium&Column dimensions&0.7 & 2.5 cm (1 ml)1.6 & 2.5 cm (5 ml)&Recommended flow rate&&1 ml/min (1 ml)5 ml/min (5 ml)&Max. pressure&&3 bar (0.3 MPa, 42 psi )&pH stability&D&&Compatibility&Stable in all commonly used buffers, reducing agents, denaturants, and detergents, see Introduction to Tagged Protein Purification for more information.&Chemical stability&For information, see Ni Sepharose& High Performance - High-performance Purification.&Storage&20% ethanol&Storage temperature&4&C to 30&C&* Protein binding capacity is protein-to-protein dependent& H2O at room temperature&D Ni2+-stripped medium && Scale-up from HisTrap& FF 1 ml via HisTrap& FF 5 ml to a HisPrep& FF 16/10 (20 ml) prepacked column (see HisPrep& FF 16/10 Column - Easy Scale-up Purification). The samples loaded contained approximately 8, 40, and 160 mg MBP-(His)6, respectively. Recovery in milligram is shown in each chromatogram. & SDS-PAGE (ExcelGel SDS Gradient 8-18) under nonreducing conditions confirms that scaling up from the 1-ml to the 20-ml column, as shown in the chromatograms on the left, does not significantly affect purity. & Purification capacity of histidine-tagged proteins can be greatly increased by connecting columns in series.HisTrap FF crude Kit 组氨酸标签蛋白的纯化试剂盒 Ni sepharose 6 fast flowHisTrap FF crude Kit 组氨酸标签蛋白的纯化试剂盒 Ni sepharose 6 fast flowHisTrap FF crude Kit 组氨酸标签蛋白的纯化试剂盒 Ni sepharose 6 fast flowtagged proteins.
