The One Step RT-PCR Master Mix Kit allows rapid, sensitive analysis of gene expression from tissues and cells. It can replace methods for detecting and quantifying gene expression such as Northern blots, in situ hybridisation, dot blots, S nuclease assays and conventional two step RT-PCR. The kit utilises recombinant Thermus thermophilus (rTth) DNA Polymerase, which acts as both a thermostable RNA dependent DNA polymerase and a DNA dependent DNA polymerase. The rTth DNA Polymerase is provided in a 2X master mix with an antibody for antibody-mediated hot start, optimised buffer, and ultrapure deoxynucleotides. Antibody-mediated Hot Start enhances specificity of both reverse transcription and PCR. The kit enables cDNA synthesis from input RNA followed by PCR amplification of the cDNA in a single reaction, with no additional hands-on requirement for buffer changes or adding reagents. Typically, detection of a specific transcript requires only 2 hours.

Unistat® technology guarantees precise, reproducible temperature control results, short heating and cooling times and large temperature ranges without the need for fluid change. All important parameters can be seen at a glance and temperature curves are displayed in graphic real time. Unistats® are equipped with up-to-date pump technology for optimal heat transfer. The pump self-regulates to ensure the best possible circulation and flow and delicate glass reactors are protected from breakage by the pumps soft start-up feature. Unistat® technology provides economic operation with reduced operating costs and efficient energy management. Unistats® are hydraulically sealed so the service life of the temperature control fluid is dramatically increased by preventing oil loss through vapours and oxidation, saving resources.

Aeolus H Serie is a high quality horizontal laminar flow workbench range for handling non-hazardous materials that require a particle free environment. These cabinets offer the highest product protection. Aeolus H horizontal laminar flow benches, have been specially designed to work in hospitals, pharmacies, IVF centres, food control, horticulture in vitro cultures, and also in electronics, optics, micromechanics, plastic Industries, etc. Horizontal laminar flow systems allow operation in sterile and particle free conditions thanks to the continuous flushing of the working area by means of a unidirectional horizontal ultra filtered air flow. The positive pressure inside the cabinet prevents inflow of ambient air from the surrounding environment into the work area.

The pGEX vectors have an expanded multiple cloning site (MCS) that contains six restriction sites. The expanded MCS facilitates the unidirectional cloning of cDNA inserts obtained from libraries constructed using many available lambda vectors. pGEX-6P-1, pGEX-6P-2, and pGEX-6P-3 each encode the recognition sequence for site-specific cleavage by PreScission Protease between the GST domain and the multiple cloning site. pGEX-4T-1, pGEX-4T-2, and pGEX-4T-3 are derived from pGEX-2T and contain a Thrombin recognition site. pGEX-5X-1, pGEX-5X-2, and pGEX5X-3 are derivatives of pGEX-3X and possess a Factor Xa recognition site.

Powerful electronic stirrers that feature a smooth start operation which prevents spills and splashing media. The speed ramps up slowly until set speed has been reached. Both models feature safe start and stop of operation via an intuitive glass slide touch panel to avoid accidental start-up. An overtemperature sensor shuts off the unit in dangerous heat-up situations, ideal for unattended continuous operation. All units are designed for continuous 24-hour operation, including challenging high viscosity applications in polymer research. High torque levels give better mixing results in less time, maintenance-free motors reduce repairs and down time. Hei-TORQUE Value 400 and Hei-TORQUE Precision 400 units have two speed gears.
