The stability of a product need to be controlled. For proteins and antibodies it may be the stability in terms of aggregation and degradation but also stability in terms of the structure or activity of the macromolecule in the matrix of interest. At SOLVE we may help in testing stability after subjecting the samples to various conditions, such as changes in pH , temperature, and various solvent conditions. It is also possible to use our services for testing the integrity of samples as a function of time, either by sending samples at regular intervals or leave to SOLVE to store and test samples at pre-defined time-points.
