Visualize and Understand Protein Co-expression during EMT


Posted by Tamar A. on Aug 7, 2019 3:10:00 AM

Careful planning and the fine tuning of experimental protocols are key to ensuring clear, interpretable scientific results. This is especially true for immunohistochemistry (IHC) studies, where each step in the often multiday process – from tissue preparation to stain development – can significantly impact the final outcome and analysis. Often, the simultaneous examination of multiple antigens is required to address specific scientific questions, which further complicates IHC protocol development. A general understating of the steps necessary to optimize IHC for multiple targets is essential to achieve reliable results. So, what are these steps?

Video: Can you trust your immunohistochemistry results?


Posted by Chris S on Jun 19, 2019 3:05:00 AM

Immunohistochemistry, or IHC, remains the simplest method for detecting biomarker expression while maintaining spatial context within tissues. You know that getting reliable IHC staining results hinges on the specificity and performance of your antibody. These are high stakes experiments, and you want to be 100% confident your antibody will detect the target of interest.

If I could only see what’s going on inside your brain...


Posted by Richard C on Jun 5, 2019 3:15:00 AM

For generations of neuroscientists, using immunohistochemistry to study the brain in its anatomical context typically meant imaging a tiny slice at a time. Using the traditional method of taking micron thick sections, fixing, staining, imaging, and, finally, stitching all the slices together, is a super laborious task, especially for large tissues. But what if you could "look" into an intact mouse brain and identify specific cells and eliminate all of the slicing and stitching?

Demystifying Multiplex IHC


Posted by Jen Z on Oct 10, 2018 3:15:00 AM

In recent years, immune checkpoint proteins in the tumor microenvironment have been under intense study. If you work in the immuno-oncology field, chances are you are either performing multiplex IHC (mIHC) or would like to. Ultimately, a multiplexed image like the one featured here provides a multi-layered depiction of a tumor, such that each antibody corresponds to a different fluorescent signal. If you want to detect more targets in your IHC, but aren’t sure how to design a panel of antibodies and fluorophores for mIHC, we’ll walk you through the process in this post.

Switching from Manual to Automated IHC? We've got your back


Posted by Chris G on Aug 30, 2017 3:00:00 AM

If you’ve ever transitioned your IHC experiments from a manual protocol to an automated platform, you may have found the conversion process to be a drag. It isn’t an easy thing to do. For that reason, we’re happy to announce our IHC Leadership in Automation initiative. This rigorous validation initiative expands on our already thorough measures, allowing researchers to not only use CST products with our recommended manual IHC protocol, but also to bridge the assay to new platforms and techniques. Our foray into the world of automated IHC aims to reduce the amount of time researchers spend on assay transfer and protocol optimization.

4 Steps to Better Immunohistochemistry: Step 1 - Antigen Retrieval


Posted by Carolyn P on May 24, 2017 3:00:00 AM

It’s Friday night and you could be out with your friends right now, but instead you’re tucked away in a dark little room filled with microscopes. Spending the evening in the lab seemed like a good choice at the time because you were certain this immunohistochemistry was going to reveal some small - but important - mystery of the universe to you. But now you’re sitting here, cursing the universe and everyone in it, because all you see when you stare down into the scope is some indistinct fuzziness. And did the controls work - meh - who’s to say? There’s no sugar coating it. It’s a fail.

In-depth characterization of immune checkpoints in the tumor microenvironment

Characterize Immune Checkpoint Proteins and T Cell Exhaustion
Using Multiplex IHC


Advances in immuno-oncology have successfully led to novel cancer therapeutics with favorable patient responses that are more durable than conventional cytotoxic chemotherapy (1). However, not all patients respond to immunotherapy; therefore investigators are trying to identify clinically relevant biomarkers with the goal of developing therapeutics based on personalized medicine (2,3).

Analysis of Immune Checkpoint Control Protein Co-expression in Breast and Ovarian Cancer Using Novel Rabbit Monoclonal Antibodies and Multiplex IHC

With an increasing number of biomarkers and, often, limited availability of biopsy material, there is a growing need for multiplexed assays for both research and clinical purposes. IHC based solutions are particularly attractive in the field of immuno-oncology, as maintaining spatial context within the tumor microenvironment provides meaningful and potentially actionable information.
