Improving Reproducibility in Real-Time PCR
Integra has reported how a leading US clinical diagnostic laboratory has, using a VIAFLO 96 handheld electronic pipette, significantly improved the reproducibility and productivity with which it carries out Real-time PCR assays.
An important source of income for the clinical diagnostic lab is the screening of patient samples for the presence of disease markers by gene expression analysis. This analysis involved transferring pre-treated patient samples from a 96-well plate source to a target PCR plate, adding the PCR master mix and then subsequently analysing the plate by real-time PCR. The lab traditionally processed around 100 plates per day and the work was all done using 12-channel pipettes. Manually filling a 96-well plate, including changing of pipette tips after every sample transfer, was acknowledged to be a time consuming task and transferring the samples often proved to be prone to error.
Tthe lab invested in an Integra VIAFLO 96 handheld electronic pipette to both load the patient samples into the plates and then to transfer the PCR master mix to the reaction plate. As a result - the work is now done in half the time. More important to the clinical diagnostic lab are two additional improvements. Transfer mistakes from plate to plate have been eliminated and now the light-sensitive PCR master mix is only exposed to daylight for a few seconds prior to the reaction, as all plate wells can be processed at the same time.
The Integra VIAFLO 96 is a handheld 96-channel electronic pipette that enables fast, precise and easy simultaneous transfer of 96 samples. Fast replication or reformatting of 96 and 384 well plates and high precision transferring of reagents, compounds and solutions to or from microplates is now as easy as pipetting with a standard electronic pipette into a single tube. Four pipetting heads with pipetting volumes up to 12.5µl, 125µl, 300µl or 1250µl are available for the VIAFLO 96. These pipetting heads are interchangeable within seconds enabling optimal matching of the available volume range to the application performed.

Proficiency Testing Rounds on Meat Speciation Available
LGC Standards has launched two new samples for meat speciation testing, as part of its established Quality in Meat and Fish Analysis proficiency testing scheme. These new samples aim to support meat-testing laboratories in the wake of the recent horsemeat scandal.
These samples are suitable for any laboratory involved in the analysis and authentication of beef products. The two new rounds are determination of equine in bovine meat and determination of porcine in bovine meat.
LGC Standards is the first PT provider to offer samples for horsemeat in beef, to address the issues arising from the recent public scandal. Following the discovery of horsemeat in a number of ready meals, food retailers in the UK have been told to carry out tests on all processed beef products.
Brian Brookman, Director of Proficiency Testing at LGC Standards said “We are aware of the increased emphasis on quality assurance within food testing laboratories. The new PT rounds from LGC Standards will allow laboratories carrying out such tests to demonstrate, and improve, the quality of their measurements, thus giving confidence to retailers, consumers and regulators in their test results on beef products.”
