EMLab P&K, a TestAmerica company, has launched new analytical services to detect pathogens in food and environmental samples using real-time PCR technology.

EMLab P&K said that it can now perform rapid analysis of pathogens such as E. coli 0157:H7 and Enterococci in hours, as opposed to traditional culture-based methods that can take as long as a week.

EMLab P&K also said that in the near future it will add new PCR tests for pathogens such as Cryptosporidium, Giardia, Campylobacter, Salmonella, and Clostridium.


Integrated DNA Technologies has added flexibility to its PrimeTime qPCR product offering by allowing customers to customize the PrimeTime Standard and PrimeTime XL qPCR assays by specifying the dye and quencher pair used on the probe and the ration of primer to probe.

The new features give researchers more flexibility for multiplex design and experimental setup, IDT said.

PrimeTime qPCR assays are 5' nuclease assays consisting of a forward and reverse primer along with a dual-labelled probe. The assays are shipped lyophilized with all components in a single tube and with enough reagents for 500 (Standard) or 2500 (XL) reactions.
