WebDec 10, 2011 · While the IgG control mimics a ChIP experiment more closely than does an “input” control, it is important that IgG control immunoprecipitations recover enough DNA to build a library of sufficiently high complexity to that of the experimental samples; otherwise, binding-site identifications made using this control can be significantly biased. WebSet a water bath or thermomixer to 65°C. Prepare 150 µl 1X ChIP Elution Buffer (75 µl 2X ChIP Elution Buffer #7009 + 75 µl water) for each immunoprecipitation and the 2% input sample. Add 150 µl of the 1X ChIP Elution Buffer to the 2% input sample tube and set aside at room temperature until Step 6.
