Responsible Science Podcast: Episode 2 - The Disruptors


Posted by Chris S on May 23, 2018 3:10:00 AM

We're excited to partner with Science: Disrupt to present a five-part podcast exploring what 'Responsible Science' means amidst the reproducibility crisis.

For the second episode of our ‘Responsible Science’ series, we dive deep into the world of startups intent on making science more responsible through new technologies, modern mentalities, and brand new tools.

Still in the Dark: AMD Patients Wait for Answers


Posted by Chris S on Apr 11, 2018 3:15:00 AM

In Mr. D’s sophomore English class, almost no subject was taboo or off limits. Even with our class projects, he encouraged us to pursue topics that truly interested us, and sometimes that meant having to educate Mr. D about something entirely new to him. But if your presentation included stunning visuals, you had to be prepared to paint a word picture. Macular degeneration rendered his otherwise healthy eyes all-but-useless.

Webinar | Achieving Reproducibility: Don't Let Antibodies Be a Variable in Your Experiment


Posted by Chris S on Jan 10, 2018 6:30:00 AM

The importance of antibodies as tools in scientific research studies cannot be understated, yet these reagents have increasingly come under fire for their lack of reproducibility. Part of the issue is that the antibody market is composed of hundreds of vendors and resellers with varying definitions for validation and consistency. Cell Signaling Technology (CST) believes that antibody suppliers should be held accountable for the products they provide, but that vendors alone cannot solve the reproducibility “crisis." How antibodies are validated and used in the laboratory is a critical component to this process. Researchers need to be more attentive to following established protocols and leverage the expertise of the scientists who have developed and tested the product they are using. Journals need to be more active in enforcing existing policies regarding materials and methods or develop more clear-cut means to identify and describe the use of biological reagents in published research. During this webinar we will address the role vendors, researchers, and journals should play in minimizing irreproducibility. We will also outline CST’s antibody validation process, while highlighting steps all users should consider when selecting and using antibodies in their research.

Successful Immunofluorescence: Experimental Controls


Posted by Ken B on Mar 8, 2017 3:00:00 AM

 Part two of a four-part series on Immunofluorescence. Check out our posts on Validation and Fixation and Permeabilization

After months of hard work, your research has honed in on a hypothesis you can test with immunofluorescence (IF). You've chosen antibodies and performed pilot IF experiments (see The Importance of Validation), and the localization of the protein appears reasonable. But how can you be sure the IF data you've acquired represents real biological phenomena? We present two examples of experimental controls in this post.

The Cost of a Failed Western Blot


Posted by Claire S on Sep 14, 2016 3:00:00 AM


Thinking about lab expenses isn’t as enjoyable as investigating your favorite signaling pathway. However, because research money is hard to come by, it is something that should be considered when picking your reagents for western blotting. It makes sense to keep the quality of your primary antibody in mind, because the success of the entire experiment depends on the antibody being reliable, specific, and sensitive. If the antibody does not perform as expected your experiment may fail . . . and the cost of a failed western blot may be more than you think.

CRISPR: Science magazine’s 2015 breakthrough of the year


Posted by Liana G on Jun 29, 2016 3:30:00 AM

CRISPR, a nifty gene-editing tool, has swept the scientific community off its feet. It has a catchy name, it’s in every other publication, it is the subject of a volatile legal dispute involving claims to its intellectual property (1), its use has instigated a multitude of summits to do with its ethical ramifications and, despite the fact that it’s less than 4 years old, the Science journal named it the ‘breakthrough of the year’ (2). To give you some perspective, the other contenders were the New Horizon’s epic visit to the dwarf planet Pluto, the discovery of a lymphatic system in the brain, and the Ebola vaccine. 

Well, you get the picture, CRISPR is a big deal, but what on Earth is it and why are scientists so smitten by it?

Roundtable Discussion on Antibody Validation


Posted by Carolyn P on Feb 17, 2016 3:00:00 AM

Antibody Validation Roundtable: Specificity + Sensitivity + Reproducibility = Validation 

Concerns about the use of incorrectly or insufficiently characterized antibodies in biomedical research have been raised by recent reports of nonreproducible research studies. Non-reproducible research studies have resulted in loss of time, resources, and scientific reputation, with publication retractions occurring in certain cases.
