Cell lysis represents the initial step for obtaining of cell samples. Several lysis methods are available for total protein extraction and fractionation. The most common lysis buffers are based on detergent solutions. However, the exact buffer composition strongly depends on the application to be used for further testing. A combination of buffer lysis and density gradient methods enables sub-cellular fractionation leading to isolation of nuclei, mitochondria and other sub-cellular structures. In our catalogue, you can find a broad range of cell and tissue lysates, which may serve as controls or references for your experiments. We also offer many proteins and control peptides, which may be useful in all your experiments involving antibodies and specialty proteins with biological activity.
