预装脱盐柱 Disposable PD-10 Desalting Columns
GE预装脱盐柱 Disposable PD-10 Desalting Columns IMPROVED:一次性脱盐缓冲液交换制备。 球蛋白分离范围:1,000-5,000 柱体积:8.3ml
Technical Information
PD-10 columns are packaged with a convenient column stand¾the PD-10 Desalting Workmate. Use LabMate Buffer Reservoir for easier equilibration.
Disposable PD-10 Desalting Columns offer an inexpensive and convenient alternative to lengthy and troublesome dialysis procedures. In minutes, biological samples are desalted and small molecular weight solutes are removed or exchanged with excellent recoveries of macromolecules.
The instructions for Disposable PD-10 Desalting Columns have been updated with two new application protocols: gravity or centrifugation, to increase the flexibility of the product. The gravity protocol allows a simple cleanup of samples with one or several columns in parallel, without the need for a purification system. The spin protocol enables runs in parallel in a standard centrifuge with minimal dilution of the eluted sample.
Four adapters are included in each product pack to enable easy centrifugation. Together with LabMate PD-10 Buffer Reservoir, wash and equilibration buffer can be applied in one step with the gravity flow protocol (order separay).
Empty PD-10 columns are recommended for use with bulk media for affordable and versatile sample preparation.
