In Pursuit of a Ready-To-Use, Shelf-Stable qPCR mix

Lyophilization of qPCR cocktail

Easy and routine methods to produce shelf-stable qPCR mixtures have practical applications in field and point-of-care diagnostic testing. Freeze-drying is one technique used to formulate shelf-stable products. Using a commercially available freeze-drying additive (2X Lyophilization Reagent), qPCR mixes were prepared and freeze-dried in several formulations using readily available enzymes and reagents...

Impact of Method Variables on Microbiota Sample Disruption

Study of microbiome

When measuring microbial diversity in samples, whether fecal, soil, or sediments, obtaining ribosomal RNA genes that are representative of the population is critical. Like any population study, sampling errors can skew results; therefore the methods used to extract DNA must yield representative DNA. The laboratories at OPS Diagnostics have analyzed variations associated with sample processing and found the overall method, equipment applied, and choice of accessory items can all dramatically affect data...(More)

AC Block™ Kit




The AC Block™ Kit provides an effective, high throughput tool for cryogenic grinding of samples. The kit includes two AC Blocks™, which are aluminum cooling blocks with absorbent inserts. When charged with liquid nitrogen, enable the AC Blocks™ to release vapor and actively cool samples during the homogenization process. ...(More)



96 Well Synergy™ Plant DNA Extraction Kit

96 well Synergyâ„¢ Plant DNA Extraction Kit

Our comprehensive 96 Well Synergy™ Plant DNA Extraction Kit includes pre-filled Homogenization Plates for mechanically disrupting up to 192 samples using a high velocity plate homogenizer, along with the purification plates and reagents for isolating contaminant-free plant DNA. Extractions performed on various sample types (e.g., Arabidopsis, corn, sorghum, wheat, etc.) have consistently yielded high concentrations of high quality DNA in a time- and a cost-efficient manner without the use of hazardous chloroform...(More)
