XenoWorks™ System

XenoWorks™ is a modular microinjection system designed to meet a wide variety of application needs.  SUTTER´s experience with precision motor control has culminated in this state-of-the-art system. The XenoWorks™ Micromanipulator uses a classic inverted joystick design for excellent ergonomics, intuitively linking the user with the micropipette.  Combined with smooth, responsive stepper-motor drives of Sutter Instrument, the XenoWorks™ Manipulator provides exceptional mechanical stability, sensitivity, and range of movement.

The XenoWorks™ Digital Microinjector was designed for precision manipulation of cells via an easy-to-use interface. The Digital Microinjector employs a self-contained vacuum channel for gentle suspension-cell holding applications.  A second channel is available for both high-pressure injection and gentle positive/negative pressure for transfer of embryonic stem cells.  Both injection duration and pressure are easily selectable using rotary knobs on the remote interface.  The internal low-speed compressor removes the need for an external pressure supply. The XenoWorks™ family also includes the Analog Microinjector for simple cell holding and transfer applications, which incorporates the same smooth response and ergonomic design of our other XenoWorks™ products.

TYPICAL APPLICATIONS

• Pronuclear microinjection of DNA into mouse zygotes
• Embryonic stem cell transfer into blastocysts
• Somatic cell nuclear transfer
• Intracytoplasmic sperm injection (ICSI)
• Piezo-assisted sperm-mediated transgenesis and nuclear transfer
