Painless Publication: How to Write a Journal Abstract


Posted by Chris S on May 9, 2018 3:10:00 AM

Have you ever sat frozen at the keyboard, facing the due date for your abstract and asking yourself how you can condense all of this information into 200 words or less? If this scenario resonates with you, rest assured you are not alone. There is a learning curve for writing an effective abstract, and thankfully there are also some tips that will help you get started and finish strong.

Are you ready to transfer your protein? Wet vs. semi-dry transfer


Posted by Neha G on Apr 18, 2018 3:15:00 AM

 You are all amped up to run a western blot to identify “your favorite protein.” The lysates have been run and proteins separated by SDS-PAGE. Now it’s time to transfer proteins from the gel to the membrane, and you’re sitting wondering….wet or semi-dry?? Or maybe you are better prepared than I was as a graduate student and you already know your next step, in which case you are aware of the pros and cons of wet and semi-dry transfer.

Keep ChIP’ing away.


Posted by Curtis D on Jan 31, 2018 6:00:00 AM

So your experiments and data are funneling you down an inescapable path. You need to show direct gene regulation by your protein of interest. You think to yourself, “Oh, ChIP...”

Have you ever wondered: Am I setting up my loading controls correctly?


Posted by Ken B on Nov 1, 2017 3:00:00 AM

You’re gathering data from all your experiments and preparing to present to your advisor and thesis committee at your annual progress report. You have an interesting hypothesis, and you have a validated antibody that recognizes your target protein on a western blot (WB). The molecular weight of the band is correct, and the expression of the target protein changes just the way you predicted it would. Now, you know — and you’d bet the house on it — when that powerpoint slide comes up, someone on your committee is going to ask about loading controls.

Fluorescent Staining Using Multiple Antibodies


Posted by Tara W on Sep 13, 2017 3:00:00 AM


The use of multiple antibodies in a single experiment can provide useful information to researchers. Co-staining with multiple antibodies and cellular dyes is a simple, low-content form of multiplex analysis. Techniques for performing multiplex analyses in cells and tissues are powerful research tools that are applicable to general cell biology studies as well as diagnostic purposes. These techniques allow researchers to detect multiple biomarkers to assess their samples. They also allow for easy colocalization studies to determine relationships between analytes. Here we describe two common techniques for fluorescent staining using multiple antibodies in the same assay.

5 Steps to Publication-Worthy IF Images


Posted by Tara W on Sep 6, 2017 3:30:00 PM

A picture is worth a thousand words, or in the case of immunofluorescent imaging, a thousand proteins. The images used to illustrate a scientific experiment should convey as much information as the text itself. Here at CST, we pride ourselves in the quality of our antibodies and our rigorous validation process. When we approve our primary antibodies for IF, we like to showcase them using high quality images generated in-house. Beyond our recommended IF protocols (check it out here), here are some additional considerations to make when planning your IF staining.

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.

Intracellular Flow Cytometry in Action


Posted by Liana G on Aug 9, 2017 9:45:00 AM


Traditionally, flow cytometry has been used to identify distinct cell types within a heterogeneous pool of cells, based on extracellular or surface marker expression, an application commonly known as immuno-phenotyping. However, this technology is also readily amenable to intracellular target detection and can be successfully applied to the study of complex signaling events.

Have You Ever Wondered: What's The Lowdown on Phospho-Specific Antibodies?


Posted by Ken B on Jul 26, 2017 3:20:00 AM

Early exploration of unmapped biological signaling pathways were carried out using radiolabeled phospho-imaging. The development of phospho-specific antibodies to detect and quantify protein phosphorylation made life easier for researchers (less 32P waste to deal with), but the interpretation of data from these experiments comes with its own set of caveats.
