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.

The study of the tumor ecosystem and its cell-to-cell communications is essential to enable an understanding of tumor biology, to define new biomarkers to improve patient care, and ultimately to identify new therapeutic routes and targets.

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 the 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.

4 Steps to Better Immunohistochemistry: Step 1 - Antigen Retrieval


Posted by Carolyn P on Jul 8, 2015 7:00:00 AM

It’s Friday night - you’re tucked away in a dark, little room filled with microscopes.You could be out with your friends right now, but you begged off because you were certain this immunohistochemistry was going to reveal some small - but important - mystery of the universe to you.

Instead, you’re sitting here, cursing said universe and all its inhabitants, because all you see when you stare down the barrel of 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.

So, what’s next? If you’re like me, you’ll wing the slide into the trash with as much gusto as you can muster and head out to find your friends. Tomorrow, you’ll re-evaluate the experiment.

But where do you start? You probably know that a highly specific, high-affinity primary antibody is key to a successful IHC. But did you know that the companion reagents (i.e., buffers, etc.), which establish the pH and ionic strength of the system, are just as important? These reagents can influence the binding of the primary antibody to its epitope and dramatically affect the outcome of the assay.

To help you pick the best reagents for your assay (and make sure those Friday nights in the lab are worth the effort) we will spend the next several posts reviewing how companion reagents affect IHC. And, as an example we will describe our experience optimizing the protocol for one of our antibodies, PLK1 (208G4) Rabbit mAb.
