You will be prompted to locate setup positions on the graph. You can move the crosshair to the designated locations on the main image using the mouse, arrow keys, or Ctrl + arrow keys. The zoom box in the upper right corner of the digitizing screen is useful for obtaining precise alignments during the axis setup process (the zoom window is for visual alignment purposes only, and all crosshair movements should be performed on the main image). After finishing the setup, click the Digitize button to automatically digitize the image. You can toggle between automatic and manual mode during the digitizing process by clicking the Pause and Continue buttons, respectively. When the digitizing process is paused (manual mode), you can access and change settings in the Options menu or add additional points manually. When the digitizing process is complete, you can accept the digitized data values and return to the main menu (or digitize additional data points).
The demo program will also allow you to test digitize one of your own images. You should scan and save your image "right side up" in a standard image format (JPG, TIF, BMP, PICT, etc.). The image should generally be saved in Line Art mode (otherwise known as black and white drawing or 1-bit mode). In order to digitize your own image, load the image into the Digitize (x,y) Graph Image portion of the demo software. The program will then display a unique Imagecode. Telephone or Email us with that Imagecode, and we will provide the corresponding Passcode that allows that image to be read. The Imagecode and Passcode are unique to each image, and are date sensitive. Although the steps involved in digitizing your own image are very similar to those described for the sample graph, each image can present its own potential difficulties, and we would advise you to contact us if additional assistance is needed.
To graph, analyze, or edit the data points from within UN‑SCAN‑IT, select Graph (x,y) Data from the drop-down Graph menu contained on the main page. The graphics buttons at the left of the graph allow you to integrate peak areas, transform the data resolution (increase or decrease the data spacing), smooth data, edit data, take derivatives, etc. Additional graphing choices are contained in the Options menu.
You will be prompted to define the lanes of interest; to do so, click on the upper left-hand and corner of the desired lane and drag the mouse cursor to the lane's lower right-hand corner. Additional lanes can be drawn using the steps above, or the lane(s) can be copied (see Options menu) to ensure equally sized lanes. To relocate any lane, move the crosshair until the desired lane is highlighted, then click and drag the lane to its proper location. Additionally, the lane positions and sizes can all be adjusted by selecting Align Regions of Interest from the Options menu or by editing the values in the grid on the right side of the screen. When all of the lanes have been defined, click the Digitize button.
A density profile plot for each lane will appear on the screen. Although many of the peaks in the profile are found automatically, you can add or delete peaks by clicking the appropriate button. The peak baseline locations can be adjusted by using the mouse to drag the endpoints of the peak baseline to the desired position (the adjustments can be seen on the image at the right of the screen). To integrate the optical intensity area for each peak in the lane, click the Quantify Peaks button. Only the data above the baseline/background will be included in the area calculation, and this value will later be displayed as Pixel Total. After Quantify Peaks and Continue are selected, the program will then repeat the density profile process for the next lane.
When the analysis of all of the lanes is complete, the band positions and locations will be shown on the gel image and the band parameters displayed in the grid at the bottom of the screen. To calculate the molecular weight, double click the bottom grid Mol Weight column for the desired segment of known value and enter the value. Entering the value for two or more segments will result in molecular weight being calculated for the remaining segments (based on a standard least squares fit of Position vs. Log MW).
You will be prompted to define the segments of interest; to do so, click on the upper left-hand corner of the desired segment and drag the mouse cursor to the segment's lower right-hand corner. Additional segments can be drawn using the steps above, or the segment can be copied (see Options menu) to ensure equally sized boxes. To relocate any segment box, move the crosshair until the desired segment is highlighted, then click and drag the box to its proper location. Additionally, the segment positions and sizes can all be adjusted by selecting Align Regions of Interest from the Options menu or by editing the values in the grid on the right side of the screen. When all of the segments have been defined, click Digitize in the lower right corner of the screen.
When the analysis of all of the segments is complete, the band positions and locations will be shown on the gel image and the band parameters displayed in the grid at the bottom of the screen. To calculate the molecular weight, double click the bottom grid Mol Weight column for the desired segment of known value and enter the value. Entering the value for two or more segments will result in molecular weight being calculated for the remaining segments (based on a standard least squares fit of Position vs. Log MW).
A calibration curve for both the Concentration and Molecular Weight values for each band can be displayed by clicking the Show Concentrations or Show Mol. Weights buttons on the toolbar of the results screen. In order to properly display the calibration curve, at least two concentration or molecular weight values must be entered in the lower spreadsheet for the standard or marker bands. The software will then use a standard least squares fit to estimate the values for the remaining bands.
The demo program will also allow you to digitize one of your own images. You should scan and save your image "right side up" in a standard grayscale image format (JPG, TIF, BMP, PICT, etc.). In order to digitize your own image, load the image into the Digitize Gel Image portion of the demo software. The program will then display a unique Imagecode. Telephone or E-Mail us with that Imagecode, and we will provide the corresponding Passcode that allows your image to be read. The Imagecode and Passcode are unique to each image, and are date sensitive.Removing the UN‑SCAN‑IT|UN‑SCAN‑IT gel Demo
