Background
One of the key factors influencing the result of Western blotting is the quality of proteins extracted from cells and tissues. In practice, detergent-based buffers such as radioimmunoprecipitation assay (RIPA) buffer, physical disruption such as sonication, or a combination of both, have become the standard for the extraction of proteins from cell membrane, cytoplasm, organelles, and nuclei. Although RIPA buffer (with 0.1% SDS) or its substitute like NP-40 buffer (without SDS), has been widely used to lyse mammalian cells and tissues, RIPA buffer is not as effective in extracting large proteins as it is in medium and small proteins. To increase the harvest of large proteins, most laboratories combine RIPA buffer with sonication which can physically break down DNA to reduce the viscosity of the lysates. However,sonication has the potential to break down large proteins. Furthermore, to inhibit endogenous enzyme activities, inhibitors need to be added to the RIPA buffer. For example, to reduce protein degradation, protease inhibitors such as aprotinin, leupeptin, pepstatin, and PMSF need to be added to RIPA buffer immediately before use. Similarly, sodiumfluoride and sodium orthovanadate must be added to inhibit phosphatase activities.
Our IntactProtein™ Cell-Tissue Lysis Kit is formulated to solve these issues. It saves you time by avoiding adding protease, phosphatase, and other enzyme inhibitors; it can also preserve the post-translational modifications (PTMs) of the cellular proteins. Overall, this product is suitable for extracting proteins of all sizes from mammalian cells and tissues.
