(A) Proteins are separated by polyacrylamide gel electrophoresis (PAGE) and (B) transferred to a membrane (e.g. nitrocellulose or PVDF) for detection. (C) The membrane is probed with a primary antibody specific for the target protein and typically followed by an enzyme conjugated secondary antibody to detect the antibody-antigen complex. The enzyme (e.g. horseradish peroxidase, HRP) acts on a substrate (e.g. electro-chemiluminescence, ECL) to emit light, (D) generating a signal captured on autoradiography film or a chemiluminescence imaging system. <a href="/support/support-by-application/western-blot/protocol.html">Learn more about perfecting Western blots</a>.</em> </p> <br/> <div><a href="https://www.bio-techne.com/resources/literature/western-blot-handbook " target="_blank"><img src="//images.novusbio.com/design/novus-wblot-banner.png" alt="western blot handbook" width="700"></a></div> <br/> <br/><br/> <h2>Western Blot Primary Antibodies</h2> <p> The success of a western blot is often dependent upon the specificity of the primary antibody.

The most common conjugate for secondary antibodies, HRP, is typically used with the chemiluminescent substrate, ECL, to produce an intense signal with low background. While chemiluminescence offers sensitive detection (low picogram) of antigens, fluorescence based detection methods have improved signal stability and allow for simultaneous detection of multiple proteins. <a href="/support/secondary-antibody-handbook">Learn more about secondary antibodies</a>. </p> <table width="709"> <tr> <td colspan="2" valign="top"> <b>Choose from:</b> </td> </tr> <tr> <td width="338" valign="top"> <ul> <li><a href="/search?keywords=novus&category=Secondary%20Antibodies&facet_conjugate=HRP">Secondary Antibodies – HRP</a></li> <li><a href="/search?keywords=novus&category=Secondary%20Antibodies&facet_conjugate=Alkaline%20Phosphatase">Secondary Antibodies - AP</a></li> </ul> </td> <td width="350" valign="top"> <ul> <li><a href="/support/GeneralSecondaryAntibodies">Find Your Secondary Antibody</a></li> <li><a href="/search?keywords=substrate&applications=Western%20Blot&category=Support%20Products">Detection Reagents - HRP and AP</a></li> </ul> </td> </tr> </table> <br/><br/> <h2>Western Blot Controls</h2> <p> Controls are vital for Western blot analysis to validate the specificity of protein bands and/or to uncover the root cause of any issues. Each experiment should include <a href="/support/loading-controls-for-western-blot">loading controls</a> to ensure samples were equally loaded in the gel and to verify the integrity of the sample. Experiments may also require positive control lysates containing the endogenous or overexpressed protein of interest, <a
