VWR® ELSD LC, ELSD FP, ELSD 100, Low Temperature Evaporative Light-Scattering Detectors

Supplier: VWR Collection
Description: These ELSD models combine simplicity, reliability and robustness for all your analyses or purifications. They allow for the detection of essentially all compounds. Detection is based on a universal property of all analytes, and does not require the presence of a chromophoric group, electro-active group, etc. Control of the system can be done either locally or via a PC. A remote shutdown mode is also provided to minimise cost and enhance system lifetime.

Thiophilic adsorption kit and thiophilic resin

Supplier: G-Biosciences
Description: Thiophilic adsorption or thiophilic chromatography is a routinely used technique for the low cost, simple purification of immunoglobulins. Thiophilic adsorption was first developed by Porath et al in 1984 and is a group specific, salt-dependent purification technique that has distinct affinity towards immunoglobulins and α2- macroglobulins. The thiophilic adsorption works on the principle that some proteins in high salt are able to bind to an immobilised ligand that contains a sulfone group in proximity to a thioether group. The bound proteins are then eluted in decreasing salt concentrations. The thiophilic resin binds immunoglobulins, including IgG, IgY and IgM, from serum, ascites or tissue culture supernatants and the purified immunoglobulins are then eluted in a near neutral aqueous buffer.

Bacterial Protein Extraction Kits, B-PER™

Supplier: Thermo Fisher Scientific
Description: B-PER® Bacterial Protein Extraction Reagents are designed to extract soluble protein from bacterial cells. The B-PER® Bacterial Protein Extraction Kit eliminates the need for harsh mechanical procedures, like sonication. The easy-to-use cell lysis solution uses mild non-ionic detergents to disrupt cells and solubilise proteins without denaturation. Enzyme supplements such as DNase I and Lysozyme allow for improved yield of large molecular weight proteins which are difficult to purify. B-PER® is also compatible with downstream protein purification methods such as GST purification and His-tagged immobilised metal affinity chromatography (IMAC).

Water softener, Aqua-Soft-System, PG 8597

Catalog Number: (141-0552)
Supplier: MIELE
Description: The Aqua-Soft system provides a continual supply of soft water and is suitable for water with a hardness up to 71° dH. It operates as a level controlled two-tank system, consisting of two cartridges with ion exchange resins and a salt reservoir. The resins are enriched with sodium ions. The hard water flows over the resins in the first cartridge, where calcium and magnesium ions are exchanged for sodium ions. At this time, no water is flowing through the second cartridge. When one cartridge is exhausted, the water is routed to the second cartridge by means of a hardness level selector corresponding to the hardness of the local water, which is inserted by customer service when the device is used for the first time. At the same time, the regeneration of the resins from the exhausted container is activated. For this treatment, brine (NaCl) is drawn from the salt reservoir. The reservoir must be replenished regularly with coarse salt pellets. Fill quantity approx. 25 kg.

Affinity purification Streptavidin Resin and buffers

Supplier: G-Biosciences
Description: Streptavidin Resin is designed for the single step small and large scale affinity purification of proteins and antibodies with a biotin tag. Biotin, a 244 Da vitamin (Vitamin H) molecule, exhibits an extraordinary binding affinity for avidin (Ka=10¹⁵ M⁻¹) and streptavidin (Ka=10¹⁵ M⁻¹). Biotin and (strept)avidin interaction is rapid and once the bond is established it can survive up to 3M guanidinehydrochloride and extremes of pH. Biotin-avidin bonds can only be reversed by denaturing the avidin protein molecule with 8M guanidine-hydrochloride at pH 1,5 or by autoclaving. The biotinylated molecules are efficiently probed with avidin or streptavidin conjugated to reporter molecules, such as peroxidases or phosphatases.
