Image types

In the realm of life science research, images play a pivotal role in conveying complex information in an understandable way. These images comprise visual representations of collected data and can often communicate what words cannot. This blog post will delve into the diversity of image types used in life science research and publications, providing a comprehensive explanation of how they are generated, the tools used to create them, and the unique information they add to research.

Microscopy Images

Microscopy images are a fundamental part of life science research. They are generated using various types of microscopes, such as light microscopes, electron microscopes, and confocal microscopes, each providing a different perspective and level of detail. These images provide a close-up view of biological structures, helping researchers understand their function and behavior. One of the inherent challenges in microscopy is the difficulty in avoiding the capture of areas with overlap, especially when trying to photograph all sample areas and when changing lens magnifications. This overlap can lead to image duplications and to potential misinterpretations. When using microscopy images, authors should ensure that the images are clear and well-focused. It's also important to correctly label the images and provide appropriate scale bars. Lastly, misinterpretation can often be avoided by providing sufficient context and explanation in the figure legend.

Western Blot Images

Western blotting is a widely used technique in molecular biology for detecting specific proteins in a sample. The images generated from this technique, known as western blot images, provide information about the protein’s size and the relative amount of it present in the sample. In western blotting, it's essential to properly label each sample. Given that the image is produced on a transparent film, marking in a manner that clearly indicates orientation is crucial. This is especially vital to avoiding accidentally flipping the samples, which could result in significant errors, duplications, or misinterpretations and potentially flawed conclusions. Authors should ensure that the bands are clear and distinct. Over- or underexposure can lead to inaccurate interpretation of the results. Proper controls and having a distinct control for each experiment are a must, and every step should be taken to maintain the integrity and clarity of the results to avoid any possible confusion.

Flow Cytometry Images

Flow cytometry is a technique used to measure physical and chemical characteristics of cells or particles. The images generated from flow cytometry, which often appear in the form of plots or histograms, provide information about cell size, granularity, and fluorescence intensity. In flow cytometry, it's vital to meticulously record each sample. Precise documentation ensures consistency and reproducibility, which are cornerstones of scientific integrity. Any discrepancies or ambiguities in labeling can lead to misinterpretations, potentially compromising the validity of the research. Authors should ensure that the gating strategy is clearly explained and that any population comparisons are statistically valid. The proper inclusion of all relevant controls in the experiment is also crucial for providing necessary reference points and benchmarks for data interpretation.

Fluorescence Images

Fluorescence imaging is a technique that uses fluorescence to generate images. This method is widely used in life science research to study the location and movement of specific molecules within cells or tissues. When using fluorescence images, authors should ensure that the images are not overexposed, as this can lead to loss of detail. It's also important to correctly interpret the fluorescence signals and provide appropriate controls to validate the results.

Immunohistochemistry Images

Immunohistochemistry (IHC) is a technique used to visualize the distribution and localization of specific cellular components within a tissue. The images generated from IHC provide information about the location and intensity of the target antigen within the tissue. Authors should ensure that the staining is specific and that any non-specific staining is appropriately controlled for. It's also important to provide a scale bar and to clearly label the tissue type and the target antigen.

In Vivo and In Vitro Images

In vivo and in vitro images are generated from experiments conducted within or outside of a living organism respectively. These images provide a wealth of information about biological processes, disease progression, and the effects of various treatments. Authors should ensure that any alterations to images, including adjustments to brightness or contrast, should be uniformly applied across all images within a figure panel to maintain consistency. Crucially, these changes should not distort or alter potential interpretations of the data. Additionally, it is vital to include appropriate controls and to label the images clearly.


In conclusion, understanding the diversity of life science image types and their appropriate usage is critical to effective research and publication. By paying careful attention to the generation and interpretation of these images, authors can avoid common mistakes and ensure the integrity of their scientific publications.


In life sciences, when we talk about diversity in images, it's not just an aesthetic term. An image serves as the visual embodiment of your research, symbolizing its integrity. Ensure that your images are well-labelled, accurately represent your data and are devoid of any modifications or repetitions. To ensure their authenticity, utilize automated tools like Proofig.
