货品编号： thermo.88513 品牌：thermo 品名：Pierce™ Protein Concentrators PES, 10K MWCO, 0.5 mL 规格：25 concentrators

产品描述： Thermo Scientific Pierce Protein Concentrators PES are disposable ultrafiltration centrifugal devices with a polyethersulfone

(PES) membrane for concentration, desalting and buffer exchange of biological samples. This product has a molecular-weight

cutoff of 10K, and can be used for processing sample volumes up to 0.5 mL.

Features of Pierce Protein Concentrators PES:

• Rapid protein concentration—sample concentration of 10- to 30-fold can be achieved in 10 minutes or less • Excellent protein recovery—unique design minimizes membrane fouling and provides high speed concentrations, even with

particle laden solutions • Instrument-compatible—use standard microcentrifuge with fixed-angle rotors; collect and recover sample without invert spinning • Versatile—easy way to perform sample concentration, diafiltration or buffer-exchange of biological samples

For easy identification, the MWCO value is etched on the side of each device. To assist with sample addition and recovery, a clear

window with graduations is located on the side of each device enabling visual determination of the retentate volume. The vertical

design of the membrane allows high flux rates, low non-specific binding and negligible protein aggregation on the membrane and

provides reliable and consistent results for processing sample volumes between 100 and 500 µL. Typical protein recovery is 90%

when the mass of the proteins in the sample is at least two-fold greater than the MWCO of the device used. Sample concentration

of 10- to 30-fold can be achieved within 10 minutes.
