ChromSwordAuto® 5: Communicates directly with the HPLC instrument in order to create a fully automated HPLC or UHPLC method development station. The unique ChromSwordAuto® software is capable of developing and optimising HPLC methods fully automatically within just a few hours. Methods already in use can also be optimised, thus reducing analysis time considerably. All you have to do is place the sample in the autosampler, set a few parameters and start the optimisation process. ChromSwordAuto® then predicts the method conditions and controls the HPLC system connected in recording the chromatograms. These are analysed by the software and the optimal conditions determined. The rapid optimisation mode can be used to provide an overview of the performance of the column/solvent system selected or to rapidly screen columns and eluents considered for use. The fine optimisation mode additionally collects and evaluates further ancillary data and produces up to 10 sets of alternative optimal HPLC conditions. Both of these operating modes can be applied in combination with column and solving switching procedures in order to try a variety of column/solvent combinations or to establish optimal pH conditions – fully automatically.

Dialysis is a routinely used technique in research laboratories to 'change' the solution a biomolecule is dissolved in. Often the buffers used to isolate biomolecules, such as proteins, are not compatible with downstream applications due to high concentrations of reagents, such as salts. A sample is placed in a bag with a semi-permeable membrane and then placed in the new solution or water. Small molecules, such as salt, can pass through the membrane, moving from an area of high concentration to low concentration. The larger molecules, such as proteins, are retained in the bag. Microdialysis is a modification of dialysis to overcome the problem of dialysing small volumes of precious samples. Microdialysis uses small devices designed for small volumes. This kit allows students to study dialysis using patented microdialysis devices.

A hands on lab activity to study immunoaffinity chromatography and use a specific antibody to purify antigenic proteins from complex samples. This technique involves performing a chromatography procedure using antigen or antibody immobilised on a chromatographic resin. The solution containing antigen or antibody is passed through the column, which specifically and efficiently captures antibodies (antigen). The captured molecules are eluted from the column as a pure fraction. In this lab activity, students perform immunoaffinity chromatography and learn how this method is utilised in research laboratories.

Supplier: G-Biosciences

Ion exchange chromatography is used to separate charged molecules from complex biological samples. The charged molecules bind to a solid support carrying an opposite charge to the molecule. Proteins contain regions of charged groups on the surface which interact with the ion exchange groups immobilised on the solid support (resin column). Immobilised proteins are eluted by changing either pH or the salt gradient or a combination of both. This lab activity involves preparation of a crude protein extract and running ion exchange chromatography for isolation of proteins.

Supplier: EDVOTEK

Most molecules have a net charge within a pH range of 2 to 10. When the pH is altered, the net charge on molecules can change drastically. In this experiment, a mixture of 2 chemicals is absorbed onto a solid support ion-exchange column and separated during elution under conditions that influence their net charge.
