Proteomics has become a vital tool for biological scientists performing research on the healthy and diseased states of living things. It involves the large scale and systematic analysis of all proteins within a given cell, tissue, or organism. Because proteins are regulated by many different internal and external stimuli, the proteome is dynamic and quantities of proteins can change from one state to the next. Therefore, in order to be of the highest utility, proteomics experiments need to both identify and quantify proteins so that comparative studies can be done, such as between healthy cells and tumor cells, or the comparison of different treatment regimens.

Nitrosamines: Where are we now?
Nitrosamines are a large group of N-nitroso compounds that share a common functional N-N=O group. They are produced by a chemical reaction between a nitrosating agent and a secondary or tertiary amine. Back in 2018, nitrosamines suddenly found themselves in the spotlight when they were unexpectedly detected in medications for high blood pressure. Since then, they have been found in several other prescription medications, including those for heartburn, acid reflux and diabetes, resulting in manufacturers recalling some common medications.

Thailand cannabis legalization
Thailand has become the first southeast Asian country to legalize cannabis for medical use. Cannabis was originally introduced into Thailand from India, and until it was outlawed in the 1930s, it was historically used as a kitchen condiment, medicine and source of fiber.
Uploading and using transcriptomics data in the OneOmics suite
RNA experiments can be created in the OneOmics suite for multi-omics analyses, enabling integration of transcriptomics data and proteomics data for biological insight. To build RNA experiments, either CloudConnect for PeakView software 2.2 or BaseSpace (Illumina) can...

Breaking down the SCIEX Triple Quad™ 7500 LC-MS/MS System – QTRAP® Ready
Sensitivity and robustness carry different meanings in the world of mass spectrometry. Generally, sensitivity refers to an instrument’s ability to achieve lower limits of detection (LOD). Robustness, on the other hand, refers to an instrument’s ability to consistently...
The honey sting
As a consumer it’s hard for me not to feel inundated with claims that our food is “all-natural” or “chemical-free” or that we should buy certain “superfoods” for their health benefits. We read labels and trust that the product we are buying is what we are truly...
