Join the club: Ten benefits of joining a professional scientific society

If you already spend all day hanging out with other scientists, the last thing you might feel like doing is joining a professional scientific society. With today’s shrinking budgets, you might also start to question whether this line on your CV is worth the membership dues. However, joining societies has many career benefits in addition…

Make Better Figures Faster Using Illustrator

Make Better Figures Faster Using Illustrator

Against the advice of journals and printers, many scientists use Microsoft Powerpoint to assemble posters and figures. You should consider upgrading to Adobe Illustrator! For generating scientific figures, Illustrator is more powerful and flexible than Powerpoint and is designed to produce print documents at high quality resolution. This means that journals will stop sending your…

How To Make Figures Right The First Time

How To Make Figures Right The First Time

Collecting the data took several years, writing the paper took several months, assembling the figures took several weeks, and converting those figures to PDFs took a frustratingly long day. You waited a month for the paper to come back from review, then two months re-doing experiments to satisfy a sadistic reviewer. Finally, your paper is…

How to transfer one SDS-PAGE gel onto two membranes

How to transfer one SDS-PAGE gel onto two membranes

Have you ever wished you could transfer the same SDS-PAGE gel twice? Sometimes, when you are blotting for many different proteins of similar size, stripping and reprobing multiple times can become impractical.  Here’s a simple diffusion transfer method that can be used to generate duplicate membranes from a single gel: Take a glass plate, or…

Train Yourself to Measure OD600 by Eye: An Improved Approach

Train Yourself to Measure OD600 by Eye: An Improved Approach

Back in August I shared my training regimen for guesstimating the OD­600 readings of microbial cultures with superhuman accuracy. Although my method is effective, I will admit that it has two shortcomings: you need to make a separate standard curve for each container type, and guesstimation is not an officially sanctioned scientific method. But now,…

Six Fixes For Antibody Co-Elution In Immunoprecipitations

Six Fixes For Antibody Co-Elution In Immunoprecipitations

Do you want to immunoprecipitate (IP) a protein with a molecular weight that is anywhere near 55 kDa or 25 kDa? Then you have an irritating problem to deal with: antibody co-elution. But don’t panic, we have six strategies for dealing with your new problem. The Problem: Typically, the IP antibody is bound to Protein…

Clean-up or Fraud? How to Avoid Photoshopping Your Way Into Disgrace

Thanks to the power of digital imaging software, faking data is a lot easier than doing real science. Clearly the honest majority of us would never deliberately distort the scientific record, but is it possible to stumble into trouble through sheer ignorance? Quite possibly. The line between innocent enhancement and deliberate fraud can be blurry…
