There are many, many different types of experiments carried out by scientists every day. Although the designs and outcomes may vary, one thing should be present in every experiment-based investigation of a hypothesis: proper controls! For every experiment, an investigator needs ...
In a previous Plasmids 101 blog, we reviewed the salient features of several popular strains of E. coli for DNA propagation. While great for cloning purposes, these E. coli strains are not usually well suited for recombinant protein expression. Many challenges can arise when ...
In previous posts for our Plasmids 101 series, we examined a number of important plasmid elements – promoters, origins of replication, protein tags, and antibiotic resistance markers (just to name a few). In this edition, we’re going to take a look at a very interesting tool ...
This post was updated on Nov 14, 2017. You've worked hard designing your plasmid – you carefully selected the optimal promoter for your gene of interest, painstakingly cloned into the perfect empty backbone, made sure to add the right tags to your gene, and may have even put a ...
Co-expression of multiple genes is valuable in many experimental settings. To achieve this, scientists use a multitude of techniques including co-transfection of two or more plasmids, the use of multiple or bidirectional promoters, or the creation of bicistronic or ...
Congratulations, you have a plasmid expressing your gene of interest (YGOI) and are ready to dive into your functional experiments! Whether you’ve cloned the plasmid yourself or obtained it from a colleague down the hall, it is always a good idea to take some time to confirm ...
Vectors (or empty backbones) are frequently used in molecular biology to isolate, multiply, or express the insert they carry in the target cell. These vectors allow you to test the function of Your Gene Of Interest (YGOI) in a controlled environment under various conditions. The ...
