Basically, you choose a gel based on two main factors: how high you need the resolution to be and what is in your samples. To make the choice simpler, I made a handy chart describing the differences between them.
*Pulsed field electrophoresis is a technique in which the direction of current flow in the electrophoresis chamber is periodically altered. This allows fractionation of pieces of DNA ranging from 50, 000-5 millon bp.
Use this chart to help you understand the differences between the two gel types and your samples will be running like athletes in no time!
Contamination in your pipette can mean contamination in your experiments, making cleaning pipettes regularly critical. Here’s an easy guide on how to do it.
At some point you have to leave small-scale cell lysis and move to large culture volumes for experiments currently in vogue, be it microarrays, total RNA libraries, or large-scale pull-downs for interactome or metabolome analysis. And at this point, you have to change your lysis method from an on-the-bench in eppendorfs to one capable of…
If you’ve worked in a lab, odds are you’ve had an encounter with filtration of one sort or another. Do you understand exactly how filters work, though? Or have you wondered why certain filters are used for certain lab applications?
Here’s an easy guide on how to maintain your lab balance. Following these tips will ensure your balance remains clean and perhaps most importantly, accurate.
Every lab has a culture, a vibe of its own. Nowhere does the distinct character of the lab become most apparent than the way in which the lab chooses to pour agar plates. You may have heard or been told to pour plates at some point in your lab career. These “plates” could be called…
Designing and running PCR reactions in the lab has become so commonplace that the number of primer design tools available can be a bit overwhelming for a beginner (or even an experienced molecular biologist!). Below are four of my favorite online programs available to make primer design quick, easy, and effective. A quick note before…
