Evaluating and Understanding the True Spread of COVID-19 through Seroprevalence

Circulation of SARS-CoV-2 in the global population led to the emergence of new variants threatening to undermine vaccine effectiveness. Understanding the immune response and its neutralizing abilities at both the patient level and globally could not only help prevent outbreaks but also mitigate the outcome for future pandemics.

Trends in Wastewater-Based Epidemiology for 2022

Two years into the COVID-19 pandemic, trends point to a transition for the SARS-CoV-2 virus into an endemic agent. As major surveillance infrastructure scales back, it will be critical to maintain a cost-effective, simple, and rapid strategy for detecting and monitoring the spread of new variants. The key to such a strategy? Wastewater, where all disease agents leave their unique signature.

Wastewater SARS-CoV-2 Testing with Droplet Digital PCR (ddPCR) Technology

Wastewater-based epidemiology indirectly monitors infection rates in a community based on pathogen levels in local wastewater. Because symptomatic and asymptomatic SARS-CoV-2 infected individuals shed viral RNA in sewer systems, analysis of SARS-CoV-2 in sewage networks can provide information about SARS-CoV-2 infections within the community. However, the accuracy of these data depends on the quality of the wastewater testing method. During the COVID-19 pandemic, Droplet Digital PCR has proven that it has the sensitivity needed to detect outbreaks and monitor SARS-CoV-2 variants in communities via wastewater testing.

Scientists for Life: A Tale of Two Tattoos

Most scientists, no matter where they are at in their career, remember the moments of wonder as they navigated lab work for the first time. Whether it’s a band on a gel, a colony on a plate, or a piece of data, those first tangible results come with a feeling of having accomplished something incredible. More than ten years later, we caught up with two scientists who immortalized that feeling in the form of matching protein ladder tattoos, and discussed how their time as undergraduate researchers led them where they are today.

Viral RNA Preparation for Molecular Pathogen Detection: A New Application for Chelex 100 Resin and InstaGene Matrix

Although vaccines have helped alleviate the negative impact of COVID-19, its persistence across many areas of the globe reveals a continuous need for rapid, accurate, and economical COVID-19 testing. But is it even possible to isolate and detect viral RNA rapidly and economically? Here we highlight a repurposed tool for improved COVID-19 detection: Chelex 100 Resin and the related InstaGene Matrix for rapid, cost-effective viral RNA preservation and detection.

The Process of Resin Screening

Process development scientists, faced with an increasing number of proteins or complex biomolecules, continuously search for robust purification methods that can be rapidly scaled for manufacturing. What are the optimal purification conditions for high throughput and yield? Which resin or resin combination best purifies the desired protein? How can an efficient, yet cost-effective process be established? The answer: use a systematic screening approach. Read on to learn more.
