While selecting the right antibody is critical, all the steps in the ChIP process are important in order to obtain great results. This technique makes use of a variety of molecular biology and proteomic methods. WebCompared with enzymatic shearing, physical shearing is more tolerant of a broad range of input material; thus, quantitation errors with physical shearing cause less variation in fragment size. Physical shearing is also a less-biased fragmentation method than enzymatic shearing because of the randomness inherent to the mechanical process (Figure 2). shut myself off from the world
