Explore the western blot workflow

Analyze, quantify, and manage western blot and gel images with confidence

 

All iBright imaging systems include integrated on-board analysis software for routine image analysis directly on the instrument. The iBright Analysis Software extends these capabilities with desktop, cloud-based, and secure software options for advanced image analysis, collaboration, and data management. We regularly update our software to add features and to continuously improve the user experience. Together, these tools help researchers quantify protein expression, perform total protein normalization, generate publication-ready figures, and manage imaging data throughout the analysis process.

 

iBright software key capabilities include:

  • Relative and absolute quantitation
  • Total protein normalization
  • Densitometry analysis
  • Molecular weight estimation
  • Colony counting
  • Image annotation and reporting
  • Image organization and data management 

Available platforms for iBright Analysis Software


On-board analysis software

Perform routine image analysis directly on the iBright imaging system. On-board analysis software automatically identifies lanes and bands and enables densitometry, molecular weight estimation, quantitation, and normalization without transferring images to a separate computer. Furthermore, up to four blots or gels can be analyzed simultaneously, greatly increasing throughput.

Watch how on-board analysis is performed.


Analyze, organize, and document your data

Find, sort, and manage your images in the gallery workspace.

Analyze your data quickly

 

Image analysis can be simplified to only a few clicks in the Image Analysis workspace of the iBright Analysis Software. Automatically analyze up to four mini blots or mini gels at a time from a single image for increased throughput. Powerful algorithms are designed to consistently and accurately select and identify lanes and band boundaries for molecular weight estimation, densitometry, or normalization. Adjustments can be made to band display sensitivity to fine-tune the number of bands displayed for analysis. Images can also be analyzed manually if preferred.

Blots analyzed using automatic analysis feature. In this example, separate blots are identified with four independent analysis frames that can be edited and analyzed separately.

The line plot option in the manual analysis workflow allows users to obtain an intensity profile along a designated line or a drawn box. This tool can help researchers quickly assess the linearity of signal or confirm the desired outcome of an experiment. By generating a line plot, users can visually examine the distribution of intensities along the designated line, providing valuable insights into the experimental outcomes.

Lane plot analysis can help one quickly evaluate an experimental outcome via examination of the distribution of intensities along the designated line or drawn box.

Adjust Image. Image adjustment options are highlighted within the Image Analysis workspace, which can be used to straighten, crop, rotate, flip, or invert images according to need and preference.

Lane profile is the intensity profile plot of the selected lane. It is plotted with average pixel intensity of all pixels at that location or band if identified on the x-axis and pixel position on the y-axis. The chart also shows the non-specific background detected by the software in gray. By default, rolling-ball background subtraction is performed using an optimal rolling ball radius produced by the software for that image. This helps to more clearly view the band boundaries and more easily adjust the bands according to profile. Hovering over the profile graph provides values for band intensity and relative front.

Use lane profile to adjust bands and leverage rolling-ball background correction.

Label for a more complete picture

 

The Annotate workspace allows the user to label the image. All annotations will appear in magenta in the viewport. Annotations and lane labels added using the annotation table will be included in the exported image and all annotations are included in the image report.

Annotate workspace—lane and band labels. Lane labels were added through a data table, and remaining labels were added using annotation tools.

Bring it all together with a complete report

 

After analysis, view your images alongside your data report. Data can be filtered to view only desired parameters. Reports can be exported to PDF format, or the raw data can be exported to Excel software for further analysis.

Exportable report helps streamline post-imaging documentation.

With the auditing functionality, you can:

  • Select to audit specific user actions and specify the audit mode (silent, optional or required)
  • Generate reports for audited user actions and SAE module changes
  • Generate reports on software or instrument actions and events

 

Committing auditable actions

 

Auditable actions can be committed onboard the iBright imaging systems instrument or in the iBright Analysis Software—Secure software. In order to track changes, changes must be committed and saved. The committed changes made can be viewed under the audit tab in the software application. Every commit creates a new version of metadata and is logged in the audit summary table in the audit tab. All committed actions are sent to SAE Administrator Console and logged under audit action records.

 

In the Commit workflow, select the Reason to commit from the selections displayed (or choose Other/Custom Reason). Enter comments as required and click on Commit.

When all the changes are done and committed, the file can be signed as per signature rules set in the SAE Administrator Console. Signature requirements (number of signatures and role required) for the selected meaning will be listed as shown below. Once all signatures are obtained, the status of the signature rule will be updated in the e-signature table for the corresponding version found in the audit tab from unsigned to signed. A signature log will be added in e-signature summary table.

 

In e-signature workflow, select the applicable e-signature meaning. Required signatures and roles will be listed. Select the applicable role and enter credentials. When all signatures are obtained, the file will be fully signed and locked.

Note: iBright Analysis Software—Secure allows partially signed files to be shared across user computers in partially signed state. When all signatures are obtained, the file will lock. iBright Instrument e-signature workflows requires all signatures to be obtained before exiting the e-signature workflow.

In iBright Analysis Software—Secure, each required role is listed, and signatures can be provided by clicking on “unsigned” status link for designated role. Partially signed files can be sent to additional users using iBright Analysis Software—Secure to complete all signature requirements.

iBright Imager SAE Mode. In iBright Imager SAE Mode, signature requirements for the designated Meaning are listed under the user icons. All signatures must be obtained at the same time onboard the iBright.

A report can be created directly from the iBright imaging systems instrument or from the iBright Analysis Software—Secure desktop software as either unsigned or signed. The file must be fully signed by all required roles/signatures prior to generating a signed report.
