Letitia Jones, a postdoc at the University of Rochester Medical Center in New York, disliked the fact that ImageJ typically uses a single box size for all bands on a gel, even if some bands stretched or smiled. “It’s a lot easier if you have someone around you who has been using it,” says Cras-Méneur. While many common questions are answered in online forums, there’s no tech support line to call if you have a specific query. ImageJ wasn’t specifically designed for gel or blot analysis, and can be intimidating to new users.

It supports stacked images, such as pictures collected from a series of different levels using a confocal microscope. With a variety of plug-ins available, ImageJ is flexible. For example, Cras-Méneur uses a plug-in that analyzes how background signal varies across an image and subtracts it from bands accordingly, instead of assuming the background is uniform. But for those who want more, many plug-ins are available coders versed in the Java language can also create their own plug-ins or macros. anything you can think of.”įor most users, standard ImageJ should be sufficient to analyze bands on a gel or Western, Cras-Méneur says. “With ImageJ I would analyze Western blots, I would do some quantifications of fluorescent microscopy, I would control the microscope. ImageJ fan Corentin Cras-Méneur, an assistant professor at the University of Michigan Medical School in Ann Arbor, appreciates the flexibility.
IMAGEJ QUANTIFY HE STAINING SOFTWARE
The public domain ImageJ software platform, developed at the National Institutes of Health and augmented by various users, is loved by some and hated by others. For researchers who want more options, The Scientist profiles five imaging programs. The simplest choice, Chen says, is to work with the software that comes with your imager.

This is particularly important for drug production and quality control, and some clinical labs may want this added layer of record keeping and password security, says Raymond Miller, a product manager at Bio-Rad in Hercules, California.

“When it comes time to publish, you need that information,” says Mark Chen, a graduate student at Duke University.įor certain users, such as those who produce pharmaceuticals, a complete data trail is required by the Food and Drug Administration, as laid down in the Code of Federal Regulations Title 21, Part 11 (CFR 21 Part 11). “I would never use JPEGs for any quantitative study,” says Wiktorowicz.Īny imaging software should save raw data files, and record any modifications users make to an image. Other formats such as JPEG compress the file size and could result in loss of crucial information. “It leaves the values intact,” he explains. Wiktorowicz, director of proteomics for the biomolecular resource facility at the university, prefers to work with TIFFs. Some use a proprietary format linked to the company’s imaging system, while many accept generic formats such as JPEG or BMP.

QuPath automated analysis immunohistochemistry phosphorylated tau traumatic brain injury.Ĭopyright © 2020 IBRO. We discuss the IHC methods necessary to utilize this analysis and provide detailed instruction on the use of QuPath in the pixel-based analysis of whole-slide images. We compared swine brains that had undergone a closed head traumatic brain injury with brains of sham animals, and found a global increase in both microglial signal expression and phosphorylated tau. This method is fast, automated, unbiased, and easily replicable. The pixel-based method of analysis herein allows for statistical comparison of global protein expression between brains and generates heat-maps of stain intensity, visualizing stain signal across whole sections and permitting more specific investigation of regions of interest.

Here we present the use of QuPath, a free and open source software, to quantify whole-brain sections stained with the immunohistochemical markers IBA1 and AT8, for microglia and phosphorylated tau respectively. Heterogeneous tissue types such as brain tissue have presented a further challenge to the development of automated analysis, as differing cellular morphologies result in either limited applicability or require large amounts of training tissue for machine-learning methods. Large scale unbiased quantification of immunohistochemistry (IHC) is time consuming, expensive, and/or limited in scope.
