<br> where the treatment variation is shown above the gel lanes, the intensity of the protein band is shown inside the boxes (a cutout of the whole blot to show just the relevant bands). GAPDH is a "housekeeping gene" whose level is rarely affected by experimental perturbations. <font color = purple> Why is it important to include data for this gene product? Thinking back to when you performed your Western analysis, did you included a similar control? </font color> | <br> where the treatment variation is shown above the gel lanes, the intensity of the protein band is shown inside the boxes (a cutout of the whole blot to show just the relevant bands).

You might also want to learn a little about standard PCR if you're not already familiar with this technique. Most biology textbooks describe PCR or you could look at some animations of the process, for example [http://www.dnai.org/b/index.html here], just follow the links through |
