Popis: The Slide-A-Lyzer® G2 dialysis cassette offers efficiency, convenience and sample protection in one package. Sample loading and removal are easily accomplished by using a serological pipette or hypodermic needle attached to a syringe. The built-in air chamber provides sample buoyancy and vertical orientation of the cassette during dialysis.

Popis: Elastase is prepared from porcine pancreas. It is lyophilised and water soluble. Elastase is chromatographically prepared by the method of Narayanan and Anwar. In the method, 2 times crystalline elastase is adsorbed on a column of DEAE-Sephadex A50 to separate elastase and non-specific protein components. The elastase component is further purified by chromatography on a column of CM-Cellulose using a sodium chloride gradient to elute the elastase. The latter is dialysed until chloride-free and then lyophilised. During its preparation the elastase is held below a pH of 5,5 for greater than 24 hours. Two times crystallised from the euglobin fraction of porcine pancreas by the method of Lewis et al. Does not contain trypsin or chymotrypsin.

Popis: Ready-to-use laboratory dialysis systems featuring proprietary Ultra-pure Biotech Cellulose Ester (CE) Membrane. Biotech Grade CE is a low protein-binding synthetic membrane available in 9 precise MWCO's with no heavy metal and sulfide contaminants. The cylindrical tubing geometry prevents sample dilution (associated with cassette-type devices) and provides open access for total volume retrieval by pipette. Only the Float-A-Lyzer® G2 assures a 95 to 98% sample recovery while maintaining 99% sample purity and <1% sample dilution. The leakproof screw-on cap with sealing o-ring provides easy access with included pipette for loading, in-process testing and sample retrieval, without the risk of needle punctures. The included floatation ring improves sample buoyancy and vertical orientation during dialysis. The sleek design allows multiple samples to be dialysed in the same reservoir.

Popis: Slide-A-Lyzer MINI Dialysis devices, 3,5K MWCO, are disposable polypropylene cups with integrated, low-binding membranes for dialysis and high recovery of proteins and macromolecules >3,5 kDa in volumes from 10 µl to 2 ml. They were developed as a convenient means for dialysing small-volume samples of nucleic acids and proteins without undue sample loss. Low molecular weight contaminant removal, buffer exchange, desalting, equilibrium dialysis, micro conjugation reactions, and concentration can be accomplished with these devices.

Dodavatel: Merck Millipore (Novagen)

Popis: D-Tube96™ Dialysers allow convenient, high throughput dialysis of 96 samples simultaneously. The device features the advantages of the D-Tube™ Dialyzer Mini in a 96-tube format. D-Tube Dialysers are easy to handle tubes with dual membranes providing a large surface area for fast, efficient dialysis. The membrane is ultra clean, EDTA-treated, regenerated cellulose that is sulfur and heavy metal-free.

Popis: 'NO-LOSS' dialyser.

Dodavatel: MP Biomedicals

Popis: There is approximately one HBr or HCl per lysine unit. The HBr/HCl allows it to be a crystalline solid and soluble in water. To remove the HBr/HCl, solubilise the product in a neutral buffer and dialyse away the salts.

Popis: These devices can be used for a wide range of applications including low molecular-weight contaminant removal, buffer exchange, desalting, equilibrium dialysis, and concentration. The cassette membrane is composed of low-binding regenerated cellulose and features a hermetically sealed sample chamber to maintain the highest possible sample retention. This type of membrane is compatible with a number of common chemicals and buffers. The colour-coded transparent frames of the Slide-A-Lyzer® cassette allow instant recognition of the MWCO of the membrane and make viewing the needle easier during sample injection.
