In my last article I introduced you to the Plexor System. And from that we already know that while in reactions that user SYBR Green for detection, fluorescence increases with accumulation of PCR product, with Plexor the fluoresence decreases. Today I want to compare some other well-known features of SYBR Green chemistry and see how…
Scientific creativity and repetitive tasks do not go well together. There is nothing worse than having to repeat the same task over and over again – I know somebody who quit science because of this and became a castle curator. So how do you minimise the amount of one of the most repetitive tasks –…
Viability PCR (vPCR) is a big step forward in PCR technology. Through the use of a simple pre-treatment of the sample(s) of interest using specific intercalating reagents, it is possible to neutralize the DNA of dead cells. As a result, only DNA from live cells will be amplified by PCR. Through the vPCR, it’s possible to…
PCR was actually one of the first lab techniques I learned as an undergrad. Despite being sometimes labeled as a pretty basic lab skill, PCR doesn’t always work as expected. This “fickle” success is due to small details or hidden hazards within the PCR workflow that can cause your seemingly uncomplicated experiment to fail. This…
Calculations can be the bane of laboratory work. Fortunately, there are many easy methods to help you do the maths you need in the lab. Here, we tell you about the different ways to calculate primer concentration depending on the starting material. For all calculations, let’s assume we have 22 nmol of a DNA primer…
It happens to the best of us. You’re minding your own business and suddenly out of nowhere your mastermix is a bubble bath and your primers are enjoying a froth party. Let’s talk about how to deal with these foamy fiends! When you’re making up your mastermix, you could have a variety of ingredients going…
