Production of membrane proteins in the cytoplasmic membrane rather than in inclusion bodies in a misfolded state is usually preferred, but often hampered due to saturation of the capacity of the Sec-translocon, resulting in low yields. WebCells that have produced protein are burst open (lysed), releasing the protein and the other cell contents. The molecules extracted from the cells are applied to a column that contains antibodies specific for the target protein. Thus, the protein is trapped in the column while other molecules from the bacteria flow through. binding of isaac ultra secret room
