SuperScript® III Reverse Transcriptase (RT) is a proprietary mutant of SuperScript® II RT that is active at 50°C and has a half-life of 220 minutes, providing increased specificity with gene-specific primers (GSPs) and the highest cDNA yield of all RTs. It is ideal for RT-PCR of a specific gene or for generating cDNA from total or poly (A)+ RNA samples. Like SuperScript® II, it synthesizes a complementary DNA strand from single-stranded RNA, DNA, or from an RNA:DNA hybrid. SuperScript® III RT is genetically engineered by the introduction of point mutations that increase half-life, reduce RNase activity, and increase thermal stability. SuperScript® III RT features:
Thermostability—half-life of 220 min at 50°C
Yield—reduced RNase H activity for more full-length cDNA
Specificity—full activity at 50°C for increased specificity with gene-specific primers
Applications—array labeling, cDNA libraries, RT-PCR, primer extension, 3´ and 5´ RACE

The µDAWN™ Multi-Angle static Light Scattering (MALS) detector performs absolute characterization of macromolecules eluting from UHPLC, determining molar mass and size independently of retention time and molecular reference standards.
The µDAWN™ Multi-Angle static Light Scattering (MALS) detector performs absolute characterization of macromolecules eluting from UHPLC, determining molar mass and size independently of retention time and molecular reference standards. This instrument offers superb sensitivity over a wide range of molar mass, size and concentrations. In most respects the µDAWN is similar to the well-established miniDAWN™ TREOS™, a workhorse MALS instrument used in hundreds of labs around the world for characterizing proteins and other molecules smaller than 50 nm in radius.
Distinctly from the miniDAWN, the µDAWN is uniquely suitable for use in conjunction with UHPLC Size Exclusion Chromatography (µSEC-MALS) thanks to its small interdetector dispersion. In some cases it may be used with ion-exchange or other types of chromatography. Regardless of the specifics, the µDAWN produces minimal band broadening in order to maintain the narrow peaks typical of UHPLC.
The µDAWN may also be used in microbatch (off-line) mode or in conjunction with a Calypso IICG-MALS system for characterization of macromolecular interactions: affinity and absolute stoichiometry, label-free and immobilization-free, as well as second virial coefficients, cross virial coefficients, average molar masses and sizes.
Today, embryonic stem cells (ESC) and induced pluripotent stem cells (iPS) represent the most significant types of pluripotent stem cells (PSC).
In the beginning, ESC were cultured on feeder cell layers, primarily murine embryonic fibroblasts (MEF), in non-defined culture media containing fetal calf serum (FCS). Later on, FCS would be replaced by somewhat more defined serum replacements and the introduction of extracellular matrix (ECM) coatings supporting self-renewal of ESC allowed for feeder-free culture using feeder-cell conditioned medium. However, the culture process remained time-consuming, laborious and poorly defined.
In recent years PSC-culture has experienced significant technical progress. Chemically defined media compositions became a standard, followed by the first xeno-free defined formulations. However, all these culture systems still depended on non-defined, xenogenic and poorly standardized ECM preparations – a contradiction in terms when using defined / xeno-free media. Importantly, research recently overcame this hurdle, identifying natural as well as synthetic ECM molecules and peptides that support undifferentiated PSC-expansion. Scientists are now capable of completely defined / humanized derivation and culture of hPSC.
Despite these recent technical advancements, the established hPSC culture systems still share unfavourable properties. Most of them use supra-physiologically high amounts of growth factors and / or contain substances purified from human or animal origin. In addition animal-derived and / or non-defined ECM is used. The PromoCell hPSC Growth Medium DXF consequently eliminates these disadvantages:
Chemically defined / xeno-free complete culture system
No human / animal derived components
Physiologically low in growth factors
This optimal culture environment allows for a well-controlled culture process, consistent and reproducible performance, robust support of pluripotency and improved cloning efficiency.
In combination with the extracellular matrix hPSC-ECM DXF and the hPSC Dissociation Buffer DXF, PromoCell provides a defined and xeno-free complete culture system for human pluripotent stem cells.
The Cadence Inline Concentrator simplifies concentrating solutions of biomolecules to an in-line, single-use, ready-to-use process.
The recirculation loop associated with tangential flow filtration (TFF) conventionally used for this process is eliminated. Pump and tube sizes are reduced, product recovery is maximized, and sensitive proteins are exposed to less shear. The Cadence Single-Use Inline Concentrator moves the product being processed through a proprietary design flow path in a pre-assembled module with all connections already in place and designed to couple to available standard tubing manifolds.
Typical applications include monoclonal antibodies, fractionated antibodies, recombinant proteins, other proteins and recombinant blood factors. The Cadence Single-Use Inline Concentrator is used to concentrate clarified bulk after fermentation, and to reduce the number or size of bags needed and increase product concentration to improve chromatography performance.
Cost projections with BioSolve software show that, compared to conventional single-use TFF, the Cadence Single-Use Inline Concentrator provides a 31% cost of goods sold and a 66% capital investment savings per batch because of the elimination of the need for intermediate tanks, ability to use smaller chromatography columns, energy savings, and the ability to couple processes to reduce downtime.

With Iris 6 INFORS HT releases a new SCADA software package for parallel bioprocess control, which brings a fresh new look and a whole raft of new features.
With Iris 6 INFORS HT releases a new SCADA software package forparallel bioprocess control. Iris 6 brings a fresh new look and a whole raft of new features to one of themost flexible and user friendly bioprocess control software programs available today. A special versionfor use with Multitron incubation shakers allows comprehensive process validation.
“Beginners will love the modern design and the easy navigation”, says Dr. Tony Allman, productmanager INFORS HT. A new ribbon menu provides quick access to the bioreactor and parametersettings. A variety of graphical displays such as correlation and bar graphs allow an easy interpretationof process data. The new version allows the user to annotate on-line graphics while a fermentation isin progress and to time-stamp samples for easy reference.
Advanced features such as the feedback control using sequences allow the experienced user toexplore all possibilities of bioprocess control. The seamless integration of both analysed and calculatedprocess parameters gives the users the possibility to achieve a combined record of all process data.“The implementation of off-line analysed parameters like OD or protein yield in the batch record file isgreat, now I can record all data in one single file”, says Dr. Michael Kaempf, Project Leader BioprocessDevelopment, EMPA (Switzerland). An enhanced reporter module makes creation of batch tickets, data export and printing both comprehensive and simple.
The Iris Parallel Bioprocess Control Software is available in 3 different packages depending on the type of equipment. The same software provides high quality data acquisition and sophisticated controlstrategies from shake flask up to pilot production.
All software packages can be qualified for validation purposes relating to FDA CFR Part 11, 21.
