Technical Reports and Presentations

The following technical reports and presentations have been created by the InnovaPrep team as well as researchers from other institutions.

Rapid Concentration of Opportunistic and Pathogenic Fungi from Source Water Samples
A poster presentation by Ariel Lewis, Assistant BioChemical Engineer, InnovaPrep Presented at the 2018 Association of Public Health Labs Meeting. "The CP Select  and high flow CPTs were  able to effectively concentrate  relatively low concentrations of Candida albicans from surface water very rapidly with a concentration factor over 2000X for the 1 L sample and over 200X for the 100 mL samples.  When paired with rapid molecular analysis methods, sample-to-answer can be achieved in a  matter of hours with greater sensitivity than other methods allow.
Detection of an Avian Lineage Influenza A(H7N2) Virus in Air and Surface Samples at a New York City Feline Quarantine Facility
Francoise M. Blachere  William G. Lindsley  Angela M. Weber  Donald H. Beezhold  Robert E. Thewlis Kenneth R. Mead  John D. NotiFirst published: 16 May 2018 
The InnovaPrep Concentrating Pipette was used to concentrate the H7N2 virus in liquid aerosol samples in this study by the CDC in which the avian flu infects a feline facility and in turn infects an attending veterinarian.
Comparison of methods to determine the microbial quality of alternative irrigation waters
The InnovaPrep Concentrating Pipette (CP-150) was compared to standard membrane filtration in a recent study by Hsin-Bai Yina of the University of Maryland, Department of Nutrition and Food Science and Jitendra Patel of USDA, ARS, Environmental Microbial and Food Safety Laboratory and published in the Journal of Agriculture Water Management.
"The concentrator method was found to be “superior in detecting virulence genes associated with E. coli O157:H7 in creek water. The concentrator method is simple, highly effective, and rapid in detecting bacterial populations in irrigation water and can be used as an alternative to traditional tedious membrane filtration method.”


Quantitative CrAssphage PCR Assays for Human Fecal Pollution Measurement
Stachler et al. Environmental Science Technology 2017, 51, 9146−9154 University of Pittsburgh, US Environmental Protection Agency. Findings confirm that viral crAssphage qPCR assays perform at a similar level to well-established bacterial human-associated fecal-source-identification approaches. These new viral-based assays could become important water quality management and research tools. a 200 mL samples were concentrated to a final volume of approximately 150 μL using an automated Concentrating Pipette with a single-use ultrafiltration hollow fiber poly(ether sulfone) tip (InnovaPREP, Drexel, MO).

The US Army Research, Development, and Engineering Command report entitled " TECHNICAL EVALUATION OF SAMPLE-PROCESSING, COLLECTION, AND PRESERVATION METHODS" reported on a comparison study of various surface sampling technologies including the InnovaPrep Backpack Surface Sampler, The M-Vac, the BisKit, Copan SRK, and Quicksilver's QS S2P kit and QS S3 swabs. "Overall, the IP Backpack performed the best for sample collection—it was the only device that collected measurable amounts of DNA from each surface tested." The report was published in 2014.

Sample Concentration Method Analysis

A Poster Presentation by Carley Ross, of Beckman Coulter, titled Detection of total aerobic counts in industrial water and biologics protein production: Sample Concentration Method Analysis utilizing portable dried reagents (DuraClone) and a bench-top flow cytometer (CytoFLEX) that compared the speed, ease, and efficiency between the Concentrating Pipette,  Glass Filtration, Centrifugation, and the PALL Sentino on 1 liter samples of cooling tower and other industrial waters. The method using the Concentrating Pipette was the easiest, fastest, and gave the best efficiencies as a front end to their CytoFlex flow cytometer. The poster was presented at the CYTO 2017 conference.
