Technically, minuscule amounts of (a) cellular lysates, from intact cells or laser capture … When the protein of interest cannot be detected through a sensitive technique (e.g., Western blot) or it is detected but at very low levels (less than micrograms per liter of culture), the problem often lies in a harmful effect that the heterologous protein exerts on the cell (Miroux and Walker, 1996; Dumon-Seignovert et al., 2004). Fc-tagged recombinant protein can be affinity purified directly from a cell culture lysate or supernatant. Protein purification methods in biotechnology that are using the procedure of “salting out” proteins of interest, or which are based on media compositions of microbes in need for elevated salt concentrations, are a challenge for downstream proteomics techniques for affinity purification or analysis.
