Glyphosate, a Polar Pest Put to Test

Jun 20, 2016 | Blogs, Environmental / Industrial, Food / Beverage | 0 comments

No other pesticide has courted more media attention and controversy in recent months than glyphosate, with governments and national agencies debating its use and health effects. The following links just show some of the media attention this organophosphorus compound has received:

However irrespective of whether it poses a risk or not the analysis of glyphosate and other polar compounds in food and beverage products has been a challenge. Attaining the required sensitivity, dealing with complex matrices and sample prep can put a serious strain and demand on your laboratory. A common practice for the analysis of glyphosate and the other associated polar compounds such as AMPA, Glufosinate, and MMPA is to derivatize the samples during the preparation.

The derivatization method may be effective however there is a serious efficiency problem associated with it, the time it takes the analysts to prep and extract the sample. Derivatization can be a time-consuming procedure and can, therefore, affect a lab’s productivity, turnaround, and margins.

In a recent presentation, on the QTRAP® 6500+ System, we conducted an in-depth evaluation into the Quantitation of Underivatized Glyphosate and Other Polar Pesticides. This comprehensive study details the various techniques and LC conditions that we tested on a variety of matrices.  In this study, we show how the SelexION® reduces interferences and can meet your required levels of sensitivity.

 

Supporting new CRISPR gene editing systems

Prime editing (PE) is a next-generation gene editing technology that utilizes a Cas9 protein fused to a prime editing guide ribonucleic acid (pegRNA) to achieve high CRISPR/Cas9 editing efficiency and precision. However, the length requirement of pegRNAs at 120–250 nucleotides (nt) and their high level of secondary structure formation present analytical challenges for the purity analysis of chemically synthesized pegRNAs during development and quality control (QC).

A new approach for comprehensive AAV evaluation including full and empty analysis

Certain next-gen vaccines and gene therapy applications rely on the usage of adeno-associated viruses (AAV) as a delivery vehicle. To ensure the safety and efficacy of viral vector drugs, multiple critical quality attributes (CQAs) need to be well characterized.

The rising tide of food allergies: Common questions and crucial insights

Allergy policies for nut-free commercial flights and nut-free childcare settings are not a rare occurrence nowadays—the reason is a rise in food allergies. Nuts are the most potent allergenic foods in terms of the amount that is required to elicit an allergic reaction and the severity of those reactions.
