Doesn’t Play Well with Others- The Chemistry of the Autoclave

Doesn’t Play Well with Others- The Chemistry of the Autoclave

While Luria-Bertani broth (LB) has long been the fuel that powered Molecular Biology and Biochemistry, there is an increasing movement towards more specialized and complex bacterial media formulations such as Terrific Broth (TB), Plasmid DNA Media (PDMR), and Autoinduction Media (ZYP-5052). These media formulations optimize E. coli cell growth and performance utilizing specialized carbon sources…

“Networking” is NOT a Dirty Word

“Networking” is NOT a Dirty Word

Merriam-Webster defines networking as “the cultivation of productive relationships for employment or business”. Less formally, networking is actively communicating with the other people you know (mostly scientists, in our case) for career advice and job openings, in addition to utilizing opportunities to meet new people for the same purpose. This is a core activity of…

It’s 10 am. Do You Know Where Your mRNAs Are?

It’s 10 am. Do You Know Where Your mRNAs Are?

For a long time we’ve been able to pinpoint the subcellular location of proteins, and the advent of FISH (Fluorescence in situ Hybridization) allowed us to locate the position of genes in the nucleus, but recent advances in RNA FISH are making it easier and easier to collect the same data about individual messenger RNAs….

The Why and How of Ethidium Bromide Assisted Partial Digests

A partial digest – typically done when you only want to cut one of two or more restriction sites in a DNA – can be a frustrating procedure to execute. The best advice anybody can give about partial digests is to avoid having to do them. However, there are times when there just aren’t many…

The Ins and Outs of Protein Concentration – Chromatography

The Ins and Outs of Protein Concentration – Chromatography

In parts one and two of this series I described how semi-permeable membranes and precipitation methods could be used to concentrate your protein-of-interest, but there is one more method that you may not have thought of for protein concentration – chromatography. While chromatography resins are an obvious choice for protein purification, they can also be…

The Ins and Outs of Protein Concentration – Protein Precipitation

The Ins and Outs of Protein Concentration – Protein Precipitation

While precipitation is an obvious choice for concentrating DNA and RNA samples, it can also be an effective way to concentrate proteins. Here in installment two of this three part series, I describe the two most common methods for protein precipitation – ammonium sulfate and trichloroacetic acid. Background Precipitation of proteins occurs primarily by hydrophobic…

The Ins and Outs of Protein Concentration – Semi-permeable Membranes

The Ins and Outs of Protein Concentration – Semi-permeable Membranes

This is the first of a three part series describing some of the most common methods for concentrating proteins. In later installments I’ll discuss using protein precipitation and chromatography to concentrate a protein. However, here I’ll detail the most popular approach – semi-permeable membranes, used for both dialysis and commercial protein concentrators. Structure of the…

Eliminate the Growth Lag with Large E. coli Cultures

Eliminate the Growth Lag with Large E. coli Cultures

If you purify proteins expressed in E. coli, then you’re probably familiar with this scenario: you come in bright and early in the morning and inoculate your large flasks of media with the overnight culture, start shaking them at 37 °C, and now you wait. And watch. And wait some more. You can’t venture far,…

Writing Your First (or next) Paper: Part IV

This is the final installment in a four part series on writing your first paper. For the first part in the series, click here, for the second part, click here, and for the third, click here. After what has potentially (likely?) been years of data collection and a month or two of writing, re-writing, wailing and gnashing of teeth,…

eBay – The other source of lab equipment

eBay – The other source of lab equipment

While almost all of you are probably familiar with the power of eBay to bring you everything from concert tickets to electronics to your very own Batmobile, you may not have realized that the world’s largest garage sale also has quite a collection of laboratory equipment. I’ve been turning to this source for equipment for…

Will the iPad Replace Your Lab Notebook?

Will the iPad Replace Your Lab Notebook?

The release of the iPad this week may bring the long-expected replacement of the paper-bound lab notebook by electronic notebooks one step closer. But are scientists, particularly PIs, comfortable with electronic lab notebooks? The rise of the tablets The concept of an electronic lab notebook isn’t anything new, and even the idea of implementing it…
