We recently came across this very interesting article about calibration curve standards, published at Restek by Dr. Landon Wiest. At the Bio-Analysis Centre, preparing calibration curves are part of our work. Thus, we would like to share this article which reveals important tips on how to do it and avoid errors. The first step to […]
When it comes to pipetting, like with most scientific procedures, precision is essential. A minor error can have a significant impact on your results. In this post, we will share 8 tips that will help you improve your pipetting skills. Pre-wet the pipette tip Before aspirating for delivery, aspirate and totally expel a quantity of […]
High-performance liquid chromatography (HPLC) (Fig.1) is a chromatographic technique that is used to separate a mixture of substances in order to identify, measure, or purify the individual components of the mixture. How does HPLC work? The sample combination to be separated and evaluated is placed into a stream of mobile phase percolating through a column […]
Drug discovery/development covers different stages until a compound is proven to be effective and safe to use. A new drug’s route from original discovery to the marketplace takes at least ten years, with clinical trials alone requiring six to seven years on average. Each successful medicine is anticipated to cost $2.6 billion in research and […]
Laboratory technicians are the “behind-the-scenes” professionals, who perform tests and experiments for research or diagnostic purposes. They help researchers and doctors reach conclusions and provide a better service/treatment for patients, respectively. To be a successful laboratory technician, certain skills are fundamental to get accurate and reliable results. Essential laboratory skills Attention to detail You must be […]
We are very proud of the academic work we undertake, and we have been assigned authorship on the following articles by our academic collaborators: C-Type Natriuretic Peptide (CNP) Inhibition of Interferon-γ-Mediated Gene Expression in Human Endothelial Cells In Vitro (click here to read article) Detection of equine atypical myopathy-associated hypoglycin A in plant […]
The most recent pandemic due to COVID-19 has certainly had a huge impact on our lives. One of the most affected sectors has been education. Face to face teaching had to be stopped and all teaching was given virtually. Thus, all lectures and practical classes were given online and students had to learn from home. […]
Polyaminopropyl Biguanide (PHMB) is a broad-spectrum antimicrobial compound found in contact lens cleaning solutions, skin disinfection treatments, and wound dressings, among other things (1). However, this substance has been banned in cosmetics in Europe since 2014. Products such as makeup, creams and body lotions used to contain PHMB as a preservative (2), but PHMB is […]
Lactulose Lactulose is a non-absorbable synthetic disaccharide made up of galactose and fructose that is also known as 1,4 beta galactoside-fructose (1). Because the human small intestinal mucosa lacks the enzymes needed to divide lactulose, it reaches the large intestine intact (1). Colonic bacteria convert lactulose to monosaccharides, which are then converted to volatile fatty […]
Symmetric dimethylarginine (SDMA) and its isomer, asymmetric dimethylarginine (ADMA) are amino acid derivatives which inhibit the body’s ability to produce nitric oxide, a molecule that aids in the maintenance of a healthy endothelium. Moreover, these compounds are formed by intranuclear methylation of L-arginine residues on various regulatory proteins and are released into the cytoplasm following […]
