Stable Cell Lines

Download Flyer for Stable Cell Lines (PDF)

 

Stable cell lines are one of the most used tools in drug discovery, toxicity testing, and basic research. Long-term stable expression of a gene of interest is usually achieved by transfection or viral transduction of a vector containing the expression cassette of the gene of interest together with a selection marker (antibiotics or fluorescent proteins). In contrast to transient expression, stable cell lines offer reproducible results for assay studies in drug discovery and development.

As One’s Most Popular PCR Enzymes

AS ONE High Fidelity DNA Polymerase is a thermostable enzyme with proofreading ability. The High Fidelity-Taq has 16x greater fidelity than Taq polymerase.

AS ONE Hot Start Taq DNA Polymerase is a modified form of AS ONE Taq DNA Polymerase, which is activated by heat treatment. During setup and the first ramp of thermal cycling, the enzyme is not active so misprimed primers are not extended.

AS ONE 2X Master Mixes conveniently includes Taq polymerase, NH4+ buffer system, dNTPs and magnesium chloride.

AS ONE Taq DNA Polymerase is a thermostable recombinant DNA polymerase, which exhibits very high activity in primer extension and other molecular biology applications.

Gravity Controller Gravite®

AS ONE INTERNATIONAL today announced it released Gravite®, a new device for simulating microgravity and hypergravity, to the global market except Japan. Gravite® is a multi-directional gravity device for simulating microgravity and hyper-gravity. By controlled rotation of two axes, the 3D clinostat minimizes the cumulative gravity vector at the center of the device and makes 10-3 g over time average. Gravite® can also create a hyper-gravity environment of 2-3 g by centrifugal force from one axis rotation.

 

Gravite® is developed by Professor Louis Yuge from Hiroshima University who is also Director of Space Bio-Laboratories Co. in Japan. Gravite® is an ideal tool that provides the simulated microgravity environment with real-time gravity monitoring for biological studies. The NASA Kennedy Space Center has introduced the device for simulated microgravity.

iP-TEC® Live Transport Device

AS ONE INTERNATIONAL, Inc. today announced the launching of iP-TEC Live Transport Device into the US market. Developed by SANPLATEC Corporation, the long-expected Live Transport Device is expected to provide strong support to promote regenerative medicine and other cellular therapy studies as well.

 

Compared with other available transport ways such as dry ice, the live transport method enables the “ready-to-use” transport of induced pluripotent stem (iPS) cells and other cells without freezing them, which not only reduces the risk that cells may be damaged or destroyed when returning to an active state, but also saves time, labor costs and reagent costs. IP-TEC Live Transport Device can maintain the system temperature at the range of 33°C~36°C for 150 hours and more when outside temperature is about 25°C. The IP-TEC Live Transport Device and all accessories are available for ordering through AS ONE INTERNATIONAL now.

Live Transport Device and Temperature Control Box

In life science industry, live cells or tissues are usually frozen with cryoprotectants and transported with dry ice if they need to be moved from one place to another for a relatively long time. There are several problems during the traditional procedure. When freezing cells or thawing cells after freezing there are always loss of cells, no mention those hours that spent on freezing and thawing cells and selected freezing medium. In some cases, cells are transported live but the stability of transportation environment such as temperature retention and vibration control is poor. SANPLATEC’s iP-TEC Live Transport Device has solved all of these problems and makes live transport possible!

 A Microgravity Simulator that NASA Kennedy Space Center introduced!

Microgravity provides a special environment where cells grow without sedimentation and convection. Several studies have shown that the formation of 3D aggregates after the cells were cultured under microgravity conditions. The 3D multicellular spheroids or tissues represent more physiologically relevant in vivo situations needed for biomedical research and drug development.

Cell Stretching Systems

Cell Stretching Systems

Menicon’s ShellPa and ShellPa Pro high-performance mechanical cell strain instruments and cell culture chambers allow researchers to explore the impact of mechanical cell strain on cells in culture. Mechanical stress applied to the cells better simulates a natural dynamic physiological environment.

Use ShellPa and ShellPa Pro to investigate:

  • Bone, muscle, cartilage, ligaments & tendons
  • Cardiovascular system
  • Cell adhesion, division, growth & cytoskeletal rearrangement
  • Stem cell proliferation & differentiation

 

ShellPa Mechanical Cell Strain Instrument

The mechanical stresses are closely related to cell proliferation and differentiation or tissue degeneration and development. Additionally, disease processes such as osteoporosis, cancer metastasis, skin disorders and muscle degeneration share a loss of tissue structure, integrity and mechanical transduction. ShellPa, the mechanical cell stretch system from Menicon Life Science, is an instrument for cell culturing that has been developed to replicate a dynamic environment inside the human body. This system is pneumatically driven by an air compressor. It is expected that cell culturing under the mechanical stress provided by this system can bring more biologically and physiologically realistic cell responses compared to a conventional static cell culturing without mechanical stress.

Features:

  • The stretch frequency and stretch ratio (stretch pattern) are easily controllable.
  • Stretch chambers are made with silicone (polydimethylsiloxane, or PDMS) and can be used with this system after being coated (e.g. fibronectin).
  • Lightweight and compact
  • Fits in standard laboratory incubator
  • Stretch frequency: 1-120 cycle(s)/min
  • Stretch ratio: 2, 4, 5, 6, 8, 10, 12, 15 and 20%
  • Use up to 6 stretch chamber simultaneously
  • Removable stretch chambers holder
  • Controller clearly indicates the accumulated operation time

IHC Detection

AS ONE INTERNATIONAL is proud to offer Histofine IHC (Immunohistochemistry) detection kits for human, mouse, rabbit, and goat primary antibodies. Uniquely, these kits use just the antigen-recognizing Fab fragment (rather than a whole antibody) to detect a primary antibody. This feature minimizes non-specific binding, thereby increasing the signal-to-noise ratio and generating cleaner results.
