Can’t See the Mouse for the Mice?! Solutions to Mouse-on-Mouse Immunohistochemistry Detection

The issue of mouse-on-mouse background is only a cause for concern for the histotechnologist working within a research environment. Those working in a diagnostic setting will probably never experience this as they will be working with human tissue with antibodies raised in a variety of species- but one species that won’t be used is human!…

Fluorescent Tyramides In Histology: A Versatile Approach For Multiplex Molecular Tissue Probing.

If you are a researcher who is using fluorescent staining on your cells and tissue sections, you should seriously consider using tyramide reagents. Why? Well, because they can have exquisite sensitivity, are easy to use, versatile and there is an increasing range of fluorophores in the pipeline. As they rely on a peroxidase catalysed visualization…

Immunohistochemistry- PAP, APPAP and Sandwiches!

You’ll give me an (enzymatic) complex! Following on from Part 1 of this article, let’s start by having a look at the two most popular enzymatic ‘sandwich’ methods; The Peroxidase anti Peroxidase method (PAP). The PAP method was the first sandwich method that I used and involves three main stages- application of primary antibody, secondary…

Immunohistochemistry- Direct vs. Indirect Methods, and a Golden Rule

In my previous article I covered different immunohistochemical staining techniques at a superficial level. In the following articles I will start to explain these technologies in a bit more detail and in which situations they should be applied. All of the following will involve additional stages when applying them, for example- serum blocking, protein blocking,…

Immunohistochemistry- an Introduction, Techniques and an Evolution Towards Robots!

The last two decades have seen a dramatic increase in the number of publications using immunohistochemistry (IHC) as a research tool to identify the spatial location of proteins of interest within cells, tissue sections and whole-mount preparations. Grinding and binding The advantages over ‘grind and bind’ methods are apparent, but the very best results will…
