Range of Standards now Expanded
Reagecon Ltd, a leading manufacturer of certified and accredited calibration and control standards worldwide, are pleased to announce the expansion of their physical standards portfolio. Responding to market demands and as part of the ongoing new product development program, several new standards have been developed and added to the following product families:
Refractive index standards have had their range increased to cover 0% to 70% for measurements using the Brix scale. Density standards with values up to 3.1 g/ml are manufactured from formulations, free from the use of toxic organic compounds.
Colour standards have now expanded so complete ranges are offered for primary colours according to the European and US Pharmacopoeias. Standards are also produced for the Gardner, Platinum- Cobalt (Hazen), ASTM and Saybolt colour scales and conventions.
Melting point standards can be provided as customer specified kits in addition to individual Standards.
Spectrophotometer standards have the linearity, wavelength, bandwidth and stray light standards provided as either sealed cuvettes or as 100ml bottles of ready to use solutions.
Provided for use with any instrument brand, these new product additions offer the analyst the most comprehensive range of accredited standards available from a single manufacturer. To download the new physical and chemical standards catalogue and to find out more about all Reagecon standards, visit

ChIP Enzymatic Shearing Kit
Porvair Sciences has announced a new Chromatrap Enzymatic Shearing Kit that contains all the necessary reagents and buffers for up to 10 chromatin preparations.
The success of a ChIP assay is highly dependent on the quality of chromatin prepared. The Chromatrap® enzymatic shearing kit allows you to determine optimal shearing conditions for your chromatin preparations, and can supply you with enough chromatin to perform up to 24 ChIPs if using standard Chromatrap® ChIP spin column kit or up to 96 IP’s if using Chromatrap® ChIP 96 High throughput microplate.
Chromatin immunoprecipitation (ChIP) is a technique used to study the association of specific proteins,or their modified isoforms, with defined genomic regions. In a ChIP assay, DNA-protein complexes (Chromatin) are identified using matching antibodies and the resulting fractions treated to separate the DNA and protein components. Polymerase Chain Reaction (PCR), Real Time PCR, hybridisation on microarrays, or direct sequencing are
typically used to identify DNA fragments of defined sequence.
The Chromatrap® ChIP assay developed by Porvair is more efficient than conventional bead based method as the solid phase porous polymer functionalised with either protein A or G is more efficient in capturing chromatin. Also it uses a spin column approach, offering significant advantage over the sepharose or magnetic beads. The levels of DNA pull down with Chromatrap® is about 25 times more than conventional methods, and the signal to noise ratios for DNA enrichment is about 2 to 3 times better even with samples anywhere between 50ng to 3000ng chromatin per immunoprecipitation.

Adopting a standard ANSI / SLAS footprint - IntegraA 384-well reagent reservoirs (100ml) are fully compatible with all liquid handling systems including the VIAFLO 384 Handheld Multichannel Electronic Pipette.
384 individual pyramidal indentations in each reagent reservoir allow maximum liquid recovery when using a VIAFLO 384 electronic pipette as well as other platforms.
VIAFLO multichannel reagent reservoirs are both economically and environmentally friendly because users can reuse the reservoir base and dispose of the reservoir inserts. These reagent reservoirs are also designed to nest within one another without sticking and come in compact, space-saving packages.
