It’s Time to Enhance Your Food Testing

Are you looking for ways to up the ante on your LC-MS/MS when it comes to food testing? Researchers here have developed a method for the analysis of approximately 400 pesticides in food samples, and their work is available for viewing in this year’s compendium. 

Top Five Misconceptions about Mass Spectrometry

Do you work in a lab handling precious samples yet, hesitant to make the move to mass spectrometry? Many laboratories just like yours continue to conduct sample analysis using ELISA assays, PCR scans, and amino acid tests because of their effectiveness. These processes work, so why change? Well, these type of analytical experiments can report false positive and negative results. You have trained your staff, know the process, and fingers crossed, not too many user errors have compromised analysis.

Rapid Separation Method for Intact Monoclonal Antibodies (Mab) Merges Charge Variant, Impurity, and Glycoform Analyses into a Single Assay

Throughout all stages of development and manufacture, monoclonal antibodies (mAbs) exhibit a great deal of structural complexity. After translation and folding, proteins undergo post-translational modifications, as well as spontaneous and enzymatic degradation, such that a single preparation of purified mAb exhibits a range of small structural changes, composed of various glycoforms and charge variants, as well as amino acids alterations due to oxidation, deamidation, isomerization, or other chemical reactions. This display of structural heterogeneity can influence the overall stability, efficacy, and safety profile; therefore, understanding the extent of structural modifications has become extremely important to drug manufacturers who continually assess mAb composition throughout bioprocessing to demonstrate stability, batch-to-batch consistency, and long-term shelf life.

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...

Full, partial and empty capsid ratios for AAV analysis: What’s the big deal?

Full, partial and empty capsid ratios for AAV analysis: What’s the big deal?

For many of you working to develop gene therapy drugs, you know that the time to market the drug is critical. Because gene therapeutics cure diseases by targeting specific genes, it is a constant race to see who develops the drug first. Unlike other classes of drugs where multiple medications can be used to treat a disease, whoever is first to develop a gene therapy drug wins.

A rising star in food allergen research: proteomics of shellfish allergen

It’s important to know what you’re eating, especially if you suffer from a food allergy.

About 220 million people worldwide live with a food allergy.1 These numbers, along with the complexity and severity of conditions, continue to rise. In America, there are about 32 million food allergy sufferers—5.6 million of those are children under the age of 18.2.2 That’s 1 out of every 13 children, or about 2 in every classroom. From a financial perspective, the cost of food allergy childcare for US families is up to $25 billion

Fast, accurate, and robust solution for routine commercial cannabis testing

As the world debates cannabis legalization for therapeutic applications and recreational use, the trends are shifting.  Medicinal use of cannabis is legal in an increasing number of countries worldwide, including 33 states and the District of Columbia in the United States. Uruguay was the first country in the world to legalize the sale, cultivation, and distribution of cannabis in 2013. In the United States, Washington and Colorado were the first to fully legalize cannabis in 2012. By the end of 2019, 10 states have legalized recreational use for adults over the age of 21, with 64% of Americans favoring the move
