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.

To fulfill its responsibility towards the consumer, BIOTECON Diagnostics decided to develop high-quality detection kits for food allergens.
To fulfill its responsibility towards the consumer, BIOTECON Diagnostics decided to develop high-quality detection kits for food allergens. Therewith, the well-known and respected spectrum offoodproof® real-time PCR kits is extended by another interesting product division.
The first allergen kits that will be launched by the company from Potsdam, Germany, are the foodproof® Celery Detection Kit and the foodproof® Gluten Detection Kit. More allergen kits for the detection of soy, peanut and hazelnut will follow soon. In combination with the foodproof® Sample Preparation Kit III for theextraction of plant DNA, this kits allows simple and safe detection of allergens in all kind of foods. Depending on the source of literature the prevalence of food allergies is between 2 – 4 % for adults and 4 -8% for children.
The foodproof® Sample Preparation Kit III allows the extraction of highly purified DNA even from complex foods or processed matrices. To validate the foodproof® Allergen Detection Kits final products, raw materials and swab samples have been successfully tested. The kit cannot be only used for foods, finished products and raw materials, but also for cleaning validations. In addition, BIOTECON Diagnostics has developed a standardized reference material, Allergen RM 800, to create a standard curve for exact quantification.
More allergen kits for the detection of mustard, sesame, lupine and crustacean will be developed next year. Also it is planned to develop multiplex kits, to detect up to three different allergen-parameters within one reaction.
Food allergens became more important, because the frequency in the population has grown in the last decades. The reasons are still not totally clear; often it is credited to changing environmental influences and diets. Even the smallest amounts of allergens can cause severe allergic reactions up to life-threatening symptoms. For the consumer, the only protection is avoidance. According to EU-regulation 2007/68/EG 14, different allergenic ingredients have to be labeled in Europe on the products. Until now there is no threshold value in Europe or elsewhere. Therefore, the zero tolerance rule applies, even foods that only contain traces of allergens have to be labeled accordingly.
Dr. Kornelia Berghof-Jäger, Chief Executive Officer (CEO) of the Germany-based corporation BIOTECON Diagnostics therefore announced that „the expansion of our product portfolio by test kits for the detection of food allergens is a consequent continuation of our strategy to cover all aspects of food safety diagnostics bymolecular methods.“
„The new product line allows the users of our foodproof® system to enter new markets with the existing laboratory equipment without any additional financial investments.” emphasizes Alois Schneiderbauer, Chief Business Officer (CBO) of BIOTECON Diagnostics stated.

For convenient and secure sterile connection of flexible tubing in large volume operations.
Kleenpak II sterile connectors allow for the dry connection of two separate fluid pathways, while maintaining the sterile integrity of both, even in an uncontrolled environment. The connector consists of a male and a female connector, each covered by an aluminum peel-away strip that protects the port and maintains the sterility of the sterile fluid pathway prior to connection.
The Kleenpak II sterile connector has been designed to allow for the connection of large processing equipment in order to obtain fast, safe and reliable sterile transfer of large volumes.With this sterile connector, large single-use systems ( > 100 L), such as the AllegroTM systems, will be operated at much faster speeds. There will be minimal fluid restriction in thetubing lines.
Different connector options are available to allow for the connection of 19 mm (3⁄4 in.) and 25.4 mm (1 in.) ID nominal tubing including a 25.4 - 38.1 mm (1 - 11⁄2 in.) sanitary flange compatible fitting for maximum operational flexibility. Kleenpak II sterile connectors can be either gamma irradiated to a maximum of 50 kGy or autoclaved up to 130°C to suit different processing requirements.
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.
