Skidaway Institute to Use FlowCam in their New Imaging Lab

Researchers at the University of Georgia Skidaway Institute of Oceanography purchased a FlowCam as part of a $226,557 grant from the National Science Foundation to acquire state-of-the-art imaging equipment to investigate microorganisms from the tiniest viruses to larger zooplankton.  The equipment will be housed in UGA Skidaway Institute's new Laboratory for Imaging Microbial Ecology or LIME.

UNE Students Excited to use FlowCam for Research

On a recent training visit to University of New England's Center for Excellence in Marine Sciences, a few of us lucky folks were given a tour of the Center's Ocean Clusters which house the student-run Phytoplankton Lab.  The Ocean Clusters are a diverse group of student-centered applied research areas spanning from phytoplankton to seaweeds to oysters and mussels and recirculating aquaculture and fisheries ecosystem experiments.  UNE just purchased a FlowCam which will be used by many researchers and students to automate and expedite plankton and particulate research.

A Colorful View From Space: FlowCam, Phytoplankton and NASA

NASA Goddard Space Flight Center’s Ocean Ecology Laboratory Field Group is mapping and monitoring the world’s oceans using satellite-based ocean color imagery.  Several of their scientists turned to the FlowCam to ground truth satellite data and identify the composition of the open ocean phytoplankton communities.

McGill University uses a FlowCam for Large Experimental Array of Ponds (LEAP) project

In July one of our technical customer support specialists, Kay Johnson, successfully completed FlowCam training at Gault Nature Reserve, Mont-Saint Hilaire - McGill University in Quebec, Canada. The research team at McGill will use the FlowCam to help with their Large Experimental Array of Ponds (LEAP) project. LEAP has been built at McGill's Gault Nature Reserve and is designed for highly replicated experiments to study how complex aquatic communities respond to environmental stressors.

FlowCam for freshwater lake systems studies in Kazakhstan

In May, our technical customer support specialist, Heather Anne Wright, traveled to Astana, the capitol city of Kazakhstan to provide FlowCam training at Nazerbayev University. The interest in using FlowCam technology in their imaging analysis repertoire came about from a unique set of conversations between Harry Nelson, our VP of Aquatic Markets and Dr. Natasha Barteneva. Dr. Barteneva is an adjunct professor at Nazerbayev University, but her primary role is Director, Flow and Imaging Cytometry Resource, Harvard Medical School. Harry and Dr. Barteneva met at Bigelow Laboratory’s Algae Culturing Techniques Course in 2014.

While the region is primarily an arid grassland, our new customers at Nazerbayev University are going to be using the FlowCam in freshwater lake systems. To complete their study, Heather Anne accompanied 2 research scientists to the National Park region to sample several of the lake systems. In addition to completing a survey of the National Park region, the team from Nazerbayev will be characterizing the biodiversity in the disappearing Aral Sea.

FlowCam for climate studies at University of Maine

In March, Heather Wright – a member of our technical support team – conducted FlowCam training at the University of Maine, Orono (UMO) for a team of researchers including Dr. Jasmine Saros and Dr. Andrei Kurbatov. Both Kurbatov and Saros work at the Sawyer Environmental Chemistry Center and conduct research to identify climatic change.

When preparing for trainings, our technical team always discusses the end-user application objectives. We also emphasize the importance of having your field or experimental samples on hand during the training. On this recent training at UMO, we worked with samples ranging from 50 year old pollen grains, preserved phytoplankton and microzooplankton, and tephra particles from volcanic ash that was trapped inside ice cores.

Key Advantage of Imaging Particle Analysis Over Light Obscuration

Omontys® – a brand name version of peginesatide – was voluntarily withdrawn from the market less than a year after the product launch. Clinical trials had demonstrated the drug to be safe and efficacious, but over 40 cases of anaphylaxis, and 7 fatalities were reported soon after the product was introduced to the market.

Peginesatide is a man-made form of a protein (mimics the structure of erythropoietin) used to treat anemia in people with chronic kidney disease who are on dialysis. Those suffering from kidney failure may have reduced amounts of this protein in their body. 

A recent article in The Journal of Pharmaceutical Sciences (JPS)1 discusses how a US Food and Drug Administration (FDA) task force investigated the Omontys events with several particle analyzers, including the FlowCam®.
