Supplementary Protocols | Life Science Research | Merck
Traditional protein assays are not suitable for analyzing extracellular vesicle preparations because the presence of lipids and other nonprotein components in the sample may interfere with protein analysis. Learn more about how IR-based assay-free quantitation afforded by Direct Detect system can be used to in extracellular vesicle preparation. -
Preparing cell lysates | Life Science Research | Merck
This page describes common challenges encountered when lysing cells and extracting proteins prior to Western blotting. Total protein concentration must be determined for these cell lysates. Variables affecting each of these steps are outlined below, as each could affect the sensitivity and reproducibility of the Western blot. -
