The graph will demonstrate the relative expression levels of the protein of interest in the control and treatment groups. With the calculated ratios and normalized values, we can plot a graph to Visualize the quantification results. By normalizing, we can compare the relative expression levels of the protein of interest between different samples or treatment groups. This normalization is essential to account for any variations in sample loading and ensure accurate quantification. To normalize the protein of interest, we divide its ratio by the ratio of the housekeeping proteins. Normalizing the Protein of Interest to Housekeeping Proteins Calculation of ratios should be performed for both the housekeeping genes and the protein of interest in both the control and treatment groups. By dividing the intensity values of the bands of interest by the control value, we can obtain ratios that represent the relative expression levels. In this case, the control value is derived from the housekeeping or actin bands. This involves dividing the intensity values of the bands by a control value. The next step in quantifying Western blots is calculating the ratios. Once the selection is made, we can proceed to the analysis phase. It is crucial to ensure that the selection includes all the bands of interest and that there is enough room underneath for further analysis. The selection should encompass the bands while avoiding unnecessary areas. This is done by using the selection tool, often represented by a rectangle icon. Once the image has been edited to perfection, we can proceed to select the bands of interest for analysis.

It may require some trial and error to find the optimal settings. Using the 'Adjust' option in the 'Image' menu, we can navigate to 'Brightness and Contrast' and make adjustments until the background is no longer visible. This can be done by adjusting the brightness and contrast of the image. In addition to aligning the bands, it is often necessary to remove the background from the image to obtain clear curves for analysis. Experimenting with different rotation angles will help achieve the desired alignment. If the bands are still slightly tilted, we can use the 'Transform' option in the 'Image' menu to rotate the image by a specific degree. First, we can invert the image by going to the 'Edit' menu and selecting 'Invert.' This will ensure that the bands appear in a straight line.

To correct any alignment issues with the bands, we can use the editing functions of the image software. Once the image is uploaded, it may appear with some imperfections, such as bands that are not aligned or a background that needs to be removed.Įditing the Image: Inverting and Rotating There are two ways to do this - either by going to 'File' and selecting 'Open' or simply dragging the image into the software. To begin the quantification process, the first step is to upload the image into the image software.

Image software allows for accurate and efficient quantification of Western blots by measuring the intensity of the bands. Quantifying the intensity of the bands on a Western blot can provide valuable information about protein expression levels. Western blotting is a widely used technique in molecular biology to detect and analyze specific proteins in a biological sample.
