Control Your Flow From Start to Finish!

As with most other experimental workflows, controls are critical in flow cytometry. Several types of controls may be used in a typical flow cytometry workflow, and these collectively serve one major purpose: to allow you to confidently distinguish your findings from background variation and non-specific staining and leave you with meaningful data.

Within a clinical laboratory where flow cytometry is used to stain cells for diagnostics, e.g., cancer, immunological diseases and others, or treatment monitoring purposes, controls become even more important since the experimental outcome can inform a patient’s prognosis and play a major role in decisions regarding treatment.

Immunohistochemistry Image Analysis – an Image Paints a Thousand Words

In our last article we looked at the workflow for a typical immunohistochemistry (IHC) experiment. Regardless of the tissue type under investigation, the target biomolecules, and the detection method chosen, it is necessary to apply a method to extract and analyse the information held on the stained slides. The detection method used will influence image analysis to some extent i.e. light microscopy or fluorescence microscopy is used to visualise slides after chromogenic or fluorescence detection, respectively. With the right equipment, it is possible to scan entire slides for easier viewing of entire tissue sections, further analysis and to get high-quality images in digital format for use in publications and presentations.

The Typical Immunohistochemistry Workflow

Immunohistochemistry (IHC) ties together immunological, biochemical and microscopic techniques to yield visual information about proteins and other macromolecules in tissues. Targets are detected through the use of labelled antibodies that penetrate tissues and specifically bind proteins and other cellular components of interest, e.g., organelles.

Beginner’s Guide to Immunohistochemistry 2: Choosing a Secondary Antibody

Welcome back to our beginner’s guide to immunohistochemistry (IHC). In this post, we’ll follow on from our last article on choosing a primary antibody, bringing you the most important considerations for choosing a secondary antibody.

Beginner’s Guide to Immunohistochemistry 1: Choosing a Primary Antibody

As with any other experimental setup, there are many factors to consider when embarking on a new immunohistochemistry (IHC) project, for example, the kind of tissue type you will stain and whether it will be fixed or frozen, the labelling/detection system, suitable staining controls, and the way in which you will analyse your data, to name a few.
