Ethidium Bromide or "EtBr" is a fluorescent nucleic acid tag commonly used in molecular biology laboratories to detect DNA and RNA. When exposed to UV light EtBr will fluoresce with a orange/red colour, this fluorescence will intensify 20-fold once bound to DNA. Although no confirming scientific studies on the subject, Ethidium Bromide is feared to be toxic due to the way it insets itself in D...
Simply wearing gloves may not provide sufficient protection against RNAse - we've taken a look at what precautions should be taken, and which gloves are suitable for RNAse free labs.
RNAse contamination
It is generally acknowledged that RNA is more prone to degradation than DNA, which may be because of the ubiquity and robustness of RNases.
This means researchers wishing to maintai...

Thanks for sharing such a great information.. It really helpful to me.. I always search to read the quality content and finally i found this in you post. keep it up!
I came across your article about "DPD Tablets" on Camlab Info, and it's a valuable resource for anyone seeking information about water testing and analysis using DPD tablets. Your explanation of their usage and significance in water quality monitoring is quite informative.
This article on nanocolor tube tests is a gem for analytical enthusiasts. The idea of zero calibration is intriguing, and your detailed explanation makes it accessible. The step-by-step process helps demystify the technique for beginners like me. The use cases you've highlighted, particularly in...
Grant have introduced the new Controlled Rate Freeze Thaw (CRFT), which is a liquid nitrogen and cryogen free controlled rate freeze and thaw system for cryopreservation in a wide range of applications. Cryopreservation is a process where biological materials such as cells, tissues...
A dipslide is a means of testing the microbial content of liquids. This is a common method of monitoring and measuring microbial activity within many systems and commonly cooling systems. Usually the use of a dipslide is the first line of defence for the testing of microbial issues that could be...
Purchasing items using donated funds without the burden of VAT will now save many Millions of pounds each year which can be put to better use in advancing scientific knowledge to provide new treatments and cures that will shape the medicines of the future.
Working with pressure/vacuum conditions in the lab is common but not all products are designed to withstand this. Products with appropriate geometry and wall thickness are suitable for working safely with pressure. For example, filtering flasks, desiccators, or flat flange vessels, as well as...
