The Biometra GmbH, a company of the Analytik Jena AG, now offers illuminators with high-performance blue light LEDs for gel documentation purposes.
Blue light transilluminators are a quite interesting alternative to UV tables as there is no risk of sample damage during illumination. This is important when samples shall be processed furthermore after gel documentation. Users also benefit from it as there is no risk of UV exposure. Blue light excitation is applicable for fluorescent dyes for nucleic acid or protein stains with excitation wavelength around 470 nm. Examples for compatible stains are: SYBR® Green, GelGreenTM, SYBR® Safe, SYBR® Gold or SYPRO® Ruby. The amber lid of the instrument allows the direct view to the fluorescent samples. There is no need for separate glasses. The new blue light illuminators are available in two versions: "BLstar 9", the handy solution for mini gels and "BLstar 16" for gels up to size of 16 cm x 20 cm.
The LiposoFast-Basic produces unilamellar liposomes by the manual extrusion of a multilamellar liposome suspension through a polycarbonate membrane of defined pore size, using gas-tight, glass syringes.
1. Principle of Operation
The LiposoFast-Basic produces unilamellar liposomes by the manual extrusion of a multilamellar liposome suspension through a polycarbonate membrane of defined pore size, using gas-tight, glass syringes. The sample is passed through the membrane by pushing the sample back and forth between two syringes.
2. Temperature Control
The entire LiposoFast-Basic can be immersed in a water bath for use with high transition temperature lipids or heat sensitive compounds.
The optional LiposoFast-Stabilizer was designed to simplify the repetitive use of the LiposoFast-Basic as well as the extrusion of highly concentrated samples. It accommodates both 0.5mL and 1.0mL syringes.

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.

MATra is an easy-to-handle, very fast and highly efficient technology for optimized transfection of cell lines and primary cells.
Magnet Assisted Transfection (MATra) is an easy-to-handle, very fast (15 minutes!) and highly efficient technology to transfect cells in culture. With MATra, all types of nucleic acids from plasmid DNA or siRNA to oligonucleotides can be delivered – even into hard-to-transfect cell types such as neuronal or stem cells. Using this new technique, nucleic acids are in a first associated with specific magnetic nanoparticles. A magnetic force is applied then and the nucleic acids will be quantitatively and quickly drawn towards and delivered into the target cells leading to efficient transfection without disturbing the membrane architecture and without causing chromosomal damage. MATra can be used with adherent or suspension cells and is functional with or without serum. Compared to other transfection techniques (e.g. electroporation or lipofection), MATra results in extremely low cytotoxicity and is very cost-effective. MATra can also be adapted to high-throughput transfection assays using robotic stations and adapted protocols.
Our PromoFectin Transfection Reagent provides highly efficient and reproducible delivery of nucleic acids into a variety of cell types, including many hard-to-transfect cell lines and primary cells. It consists of a non-liposomal polymer that is stable, water-soluble and free of any components of animal origin. PromoFectin compacts and protects the nucleic acid of interest, enables efficient transport into the cells via endocytosis and allows for a rapid and almost complete release of the intact nucleic acid into the cytosol – all of which favor the delivery to the nucleus. Transfection with PromoFectin results in very low toxicity and is therefore ideally suited for the transfection of very sensitive cells, yielding optimal effects on gene expression. It can be used for adherent and non-adherent cells and the protocol does not require a medium change. Special cell type-specific PromoFectin variants are also available, which have been developed for an optimized transfection of e.g. endothelial cells (HUVECs, HDMECs etc.), hepatocytes, macrophages, dendritic or neuronal cells.
In addition, PromoKine provides a range of small-sized reporter plasmids (beta-galactosidase, luciferase, GFP, CAT, and SEAP) as well as fusion plasmids, which allow high-level expression of a target gene of interest with a GFP or luciferase fusion tag at its C- or N-terminus. The corresponding reporter assays (luciferase, beta-galactosidase & GFP) are also available.

All in all, the DynaPro DLS Plate Reader will help you increase your productivity by a factor of 10 or more when sizing biomolecules and other nanoparticles compared to conventional batch DLS systems. With the DynaPro Plate Reader, you can perform the classic DLS applications but with more confidence. Samples can be loaded in duplicate or triplicate, and scanned several times by the Plate Reader, providing you with data that are a true measure of sample repeatability and reproducibility. Due to the low sample volumes and automated capability, these experiments can be performed in less time and without the hassles of conventional batch DLS. Moreover, because the DynaPro Plate Reader can operate in an unattended fashion, there is no additional ‘cost’ – your valuable time – associated with exploring a much larger number of solution conditions or protein or other nanoparticle constructs. The DynaPro can perform accelerated stability, thermal melting, and temperature studies of multiple samples in parallel.
New: The DynaPro Plate Reader is now available with Extended Temperature Control and On-board Camera! The onboard camera in the DynaPro Plate Reader II can automatically acquire and store images of each well, giving scientists a new dimension of data acquisition, and instant insight into the behavior of their samples.
