AS1 Attends NZMS/NZSBMB Conference

AS1 attended the annual conference of the New Zealand Microbiological Society Inc and the New Zealand Society for Biochemistry and Molecular Biology in November.

The focus of this years conference was the challenge of being a scientist in the post-genomic era. The conference presentations discussed the challenge of functional genomics, New Zealand’s biological heritage and science for technological innovation.

AS1 display visitors were particularly interested in Biolog, DWS Anaerobic and Hypoxia cabinets, Presens oxygen monitoring systems and AWEL sample preparation systems.

It was an excellent meeting with a lot of interesting presentations and posters.

FAQ: PreSens Products

How Can You Do Oxygen Measurements in ppm?

PreSens oxygen sensors (like other sensors, e. g. electrodes) measure the partial pressure of oxygen. To get ppm you need the saturation cencentration of the system / solvent the sensor is used in. ppm calculated by the Fibox works for aqueous solutions only, according to:

100 % air saturation is 9 mg / 1000 g H2O (298 K) and 1 atm, i. e. 9 ppm

If the solubility  of oxygen in the solvent is considerably higher than in water, ppm at saturation in higher.

Do you have any other questions? Feel free to contact Anna.

PreSens New Product: Microx 4 and Microx 4 trace

Today we have the pleasure to introduce to you our brand new Microx 4 & Microx 4 trace! For the time being, it is the sole independent display controlled device on the market handling non-invasive and microsensors as well as sensor probes. Together with this stand-alone, portable fiber optic oxygen meters we present you two new sensor types: PSt7 for measurements in normal oxygen range (detection limit 15 ppb, 0 - 100 % oxygen) and PSt8 (detection limit 3 ppb, 0 - 10 % oxygen) for measuring oxygen traces.

PreSens will present the devices for the first time at the Analytica in Munich, April 1st - April 4th, 2014. The official start for sale will be on May 5th, 2014. But we will surely accept your orders beforehand.

Additionally, please note that we harmonized two of the technical specifications for hydroplates and hydrodishes. By next week we will also present new single-use flow through cells for oxygen and pH to our customers.

TITLE:  Phenotype MicroArrays: An Overview of the Technology and Applications

PRESENTER:  Barry R. Bochner, Ph.D., CEO & CSO, Biolog, Inc., Hayward, CA  Biography and New Zealand Presenting Schedule

Phenotype MicroArray (PM) technology allows a biologist to test thousands of phenotypes of a cell line in a single experiment, to gain a comprehensive overview of the metabolism, physiology, and pathway fluxes.It provides phenomic and metabolomic information that is complementary to genomic or proteomic analysis and often more easy to interpret and more useful.The PM technology platform is applicable to a wide range of cells including bacterial, fungal, or animal and enables metabolic analysis in the context of genotype-phenotype studies.  For example, it can be used for (1) analyzing cells with mutations to determine the metabolic and physiologic effects of genetic differences, (2) studying and defining cell metabolism and metabolic regulation, (3) understanding the interplay of environment and hormonal signals on cell metabolism and physiology, (4) optimizing cell culture conditions, and (5) looking at the effects of drugs and other chemicals on cellular pathways.  For microbial cells, recent work has demonstrated the utility of the technology for determining culture conditions that turn on and turn off production of toxins and other secondary metabolites that microbes can produce.  The technology also has many applications with human cells, including the assay of the effects of microbial toxins.  Specific examples and discoveries will be presented to illustrate the many uses of PM technology.
