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…
Here’s a quick guide to cleaning and maintenance, to help you overcome your fears of the monsters lurking in your water bath.
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…
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…
You might be proud of your pipetting skills (if not, check this article on how to stop pipetting errors from ruining your experiments) and be churning out data faster than a liquid handling robot, but beware… you might also be pipetting yourself out of a job. I almost did. Pain due to pipetting is common….
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: Protein transfer by this diffusion…
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,…
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…
I once knew a postdoc who was absurdly accurate at guessing the optical density of microbial cultures. I was jealous – imagine how much time I would save if I could spec my cultures just by looking at them! Since I lacked the innate optical talents required to compete with my friend, I developed a…
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…
