Real-time thermal cyclers
A real-time thermal cycler is a laboratory equipment that allows the real-time polymerase chain reaction (qPCR) to be carried out efficiently and quickly; by means of the automatic and cyclical realization of the temperature changes that are required for the amplification of a deoxyribonucleic acid (DNA) chain; from a thermostable enzyme. The objective of this type of PCR is to detect and quantify the specific nucleic acid sequences by means of fluorescent molecules in the reaction, where the increase in fluorescence is proportional to the increase in the amount of amplified DNA molecules in the reaction.
Fluorometer vs. Spectrophotometer
A fluorometer is a piece of equipment that allows the analysis, identification and quantification of chemical substances with molecules capable of presenting fluorescence, using the technique of fluorescence spectrophotometry or fluorometry. We can say that this equipment is a special optical device used in laboratories, capable of measuring the fluorescent quality of biological or mineral samples.
Electrophoresis and Gel Documentation Systems
Gel electrophoresis is a widely used technique in life science laboratories to separate macromolecules such as DNA, RNA, and proteins. In this technique, molecules are separated according to size and electrical charge.
Study finds that staying thin and avoiding obesity could be help
If you diet and hit the gym regularly but are not seeing the results you hope for, it could be down to your genes.In a new study, thin people were shown to have specific gene regions in their DNA keeping them slim, while also having fewer gene variants that have been linked to being overweight.
Discoveries in thymidylate and their expression phenotypes
“Timidylate Synthase” is known as the expression of the TYMS gene located in the short arm, becoming a homodimeric methyltransferase enzyme, which significantly aids in the repair of DNA in humans.
