NettetProtein extraction. Protein extraction is a key step for analytical methods such as Western Blot and enzymatic assays. Below, Bertin’s top scientists have shared best practices to improve your homogenization protocol for a wide range of tissues, including tips to preserve the integrity of the proteins in your samples and achieve optimal yield. NettetCentrifuge for 15 minutes at 1000 x g within 30 minutes of collection. An additional centrifugation step of the plasma at 10,000 x g for 10 minutes at 2-8 °C is recommended for complete platelet removal. Assay immediately or aliquot and store samples at ≤ -20 °C.
