产品说明
一般描述
Amicon® Ultra 4 mL centrifugal devices with Ultracel® 50,000 Dalton molecular weight cutoff filters provide fast ultrafiltration, and reliable retention of macromolecules. For example,BSA (67 kDa) at 1 mg/ml initial concentration is retained at >95% .
The vertical design and available membrane surface area provide fast sample processing, high sample recovery (typically greater than 90% of dilute starting solution), and the capability for 80-fold concentration. Solute polarization and subsequent fouling of the membrane are minimized by the vertical design, and a physical deadstop in the filter device prevents spinning to dryness and potential sample loss.
The concentrate is collected from the filter device sample reservoir using a pipetter, while the ultrafiltrate is collected in the provided centrifuge tube. The device can be spun in a swinging bucket or fixed angle rotor. With their vertical membrane design and deadstop, Amicon® Ultra 15 mL filters deliver the highest recovery with short spin times.
应用
- Ultrafiltration with 50,000 Dalton molecular weight cutoff Ultracel® membrane.
- Concentration of biological samples containing antigens, antibodies, enzymes, nucleic acids, or microorganisms.
- Purification of macromolecular components found in tissue culture extracts or cell lysates and protein removal prior to HPLC.
- Concentration of dilute or pre-purified proteins from column eluents.
- Desalting, buffer exchange and protein dialysis.
- Size exclusion and protein fractionation.
特点和优势
- Ultracel® regenerated cellulose membrane with 50 kDa NMWCO delivers retentate recovery of greater than 90%.
- Vertical membrane reduces concentration polarization for ultra-fast spin times (as fast as 5 minutes).
- Heat-sealed membrane minimizes downstream extractables.
- 100% integrity tested for reliable performance.
- Convenient sample monitoring with translucent housing and volume gradations.
- Direct pipette sample access eliminates processing step to recover concentrate.
- High concentration factors of 80–100X.
