Qualitative Western Blot: Compare Target Proteins Steps

The information below explains the purpose of each step in the Experiment workflow (called a "page") and provides instructions and tips for completing each page.

Name

To help with record-keeping, give every Experiment a distinct name. The description field provides space for you to include important details about the Experiment.

Set up images

Ensure the correct images have been chosen, then enter information for the proteins being analyzed. If you have detected more than one protein in a channel, click to add information for an additional protein.

Click the zoom buttons above the image to make the displayed image smaller or larger . A zoom level, shown as a percentage relative to the size of the software window, is shown next to the zoom buttons.

Define lanes

The Define lanes page identifies lanes on the image for analysis. To find lanes, draw a boundary that encloses all the lanes on the image.

By default, Auto mode automatically performs lane finding. Manual mode is also available.

Specify replicate lanes

The Specify replicate lanes page allows you to link replicate lanes for analysis. The numbered rectangles displayed on the page correspond to the lanes on your blot.

Add lane details

Record important details about your samples.

Assign MW marker

Assign a molecular weight marker to estimate the molecular weight of bands. Estimated molecular weights will be available in the Analysis Table of the Quantify bands page.

You can estimate the molecular weight of target bands in one channel using a marker in another channel when you link a Band Channel to a Marker Channel.

Quantify bands

The Next button will not be active until you have identified a band in each lane (aside from lanes that you marked as Not Used or MW Marker on the Add lane details page).

Set up chart

Graph the Lane Amount (entered on the Add lane details page) against Lane and Band Signal on this page.

Select Include Total Lane Signal in chart to include the Lane Signal in the chart along with Band signals.

Edit Chart Selection

Click Edit Chart Selection to choose which lanes and which bands to include in the chart.

Review and report

The Review and report page allows you to export a PDF file containing the data and image from the validation or export the image and data table individually.

The data in the report is organized into sections. Click to expand a section to view data and export options.

Done

Click Done to mark this Experiment as complete and return to the Experiment List.
