WebMETHOD. 1. Wash the Protein A or Protein G resin with at least 10 column volumes of 0.1 m TBS or 1× PBS. 2. Dilute the serum 1:1 with the buffer used to wash the column. Centrifuge the diluted serum at 10,000 g for 15 min before loading onto the column to remove cellular debris. 3. WebThe proteins in these so-called inclusion bodies are mostly inactive and denatured. In addition, dimers and multimers may be present. However, the expression of recombinant proteins in inclusion bodies can also be advantageous: the recombinant protein deposited in inclusion bodies can be 50% or more of the total cellular protein.
