Making the Most of Quiet Days in the Lab: From Gloomy to Glorious

It’s Monday morning. You arrive in the lab armed with a large coffee and feeling rested after a non-lab weekend. You check your email and calendar and peek into your PI’s office. Today will be a rare non-experimental day, a day that some love and others dread: a day to clean up and get ready […]

SAGE Part 2: LongSAGE, RL-SAGE and SuperSAGE

SAGE, or serial analysis of gene expression, is a technique that enables you to digitally analyze the entire gene expression profile of a cell(s). Before this technique, scientists were limited to studying a few gene’s expression at once by a technique called the expressed sequence tag approach. The coolest part of SAGE is you don’t […]

Vital for Soup, Vital for Labs: Serial Analysis of Gene Expression (SAGE), part 1

Some techniques can sound very dry but this isn’t one of them! SAGE was first described and published by Velculescu et al. in 1995. At the time, techniques like RNA blotting and expressed sequence tagging were used to study gene expression. However techniques like these were slow and very limited. The speed of SAGE and […]

When PCR Gets RACE-y: From Unknown mRNA Segments to Sequenced cDNA

Normally you need two primers to amplify your segment of interest – one for the 3′ end of your segment of interest and one for your 5′ end. But if you don’t know the sequence of the regions you’re hoping to amplify this can be a problem! Rapid Amplification of cDNA Ends (RACE) is a […]

The BOOM Method for Nucleic Acid Purification: The Ultimate Chick Flick?

The Boom method, or Boom nucleic acid extraction method, is a solid phase extraction technique for isolating nucleic acids from a solution of biological matter. This is just a fancy way of saying you use this technique to expose and remove the nucleic acids from a cell. First developed by William R. Boom, the Boom […]

Origami in Nature: Protein Structure Prediction

Predicting how proteins will fold in vivo is a Holy Grail of proteomics and theoretical chemistry. Current hopes are that this can be achieved by designing an in silico platform that can predict protein folding, either de novo (a.k.a. from scratch) or using known proteins as a guide. What would we need to do, why […]

My job as a Clinical Study Coordinator

Clinical Trial Coordinator, Clinical Study Coordinator, and Clinical Research Coordinator are all names for the same job and refer to the person responsible for the day-to-day running of human trials. Usually when I tell someone that I’m a Clinical Study Coordinator, they have no idea what that means. I guess it’s like when someone tells […]

Time to Instigate Nested PCR

How to Obtain a Purer PCR Product and Reduce Non-specific Amplification Unless you’ve gotten your hands on some miraculously specific primers, amplification of only your target sequence without non-specific amplification can be very challenging. Thankfully, a clever and surprisingly simple solution is at hand! A Quick Recap of the Basics In PCR, you design your […]

Expanding Possibilities: Why You Need to Look into Viral Transduction

We have already looked into the different types of viral expression systems and when you might use one over another in my previous article. But why would you use viral transduction over similar techniques like plasmids? Just a reminder: Transfection is a lab technique where nucleic acids or proteins may be introduced into cells. When […]

Comparing Viral Vector Expression Systems

Some viral vectors are the little black dresses of cloning and expression experiments: They work for almost any occasion and always give you the results you were hoping for. Other vectors are more like ballgowns that only come out of storage for special occasions. Let’s wade through all the information out there and take a […]
