The ECM 2001+ Electrofusion and Electroporation System provides fast, efficient cell fusion in hybridoma production, hybrid cell formation and nuclear transfer applications, as well as square wave electroporation for transfecting genes and other molecules into mammalian cell lines.

ECM 2001 Generator

The ECM 2001+ is a multifunctional electrofusion and square wave electroporation generator. The ability to generate both AC and DC waves allows for fast and efficient cell fusion in hybridoma production, hybrid cell formation, and nuclear transfer applications. This system is powerful enough to yield high transfection efficiencies for cell lines and difficult to transfect cell types including stem cells and primary cells. The gentle square wave pulse also allows for high cell viability of these cell types.

The ECM 2001+ is intended For Research Use Only. Not for use in diagnostic, pre-clinical, or clinical procedures.

The Hybrimune Hybridoma Production System is an advanced electrofusion system for fast, efficient cell fusion in hybridoma production, hybrid cell formation, and dendritic-tumor cell fusions.

Yield improvements of 10 fold or more compared to standard PEG fusion

The Hybrimune system includes an innovative fusion chamber design, proprietary BTXpress® Cytofusion medium and sophisticated, tri-phasic electric field pulses that quickly position cells and disrupt cell membranes for maximum cell fusion efficiency with short cycle-times and minimal heating or turbulence for excellent cell viability. In addition, Hybrimune delivers a cell alignment waveform which is a patented sequence that enhances hybridoma yield.

The Hybrimune system consists of a user-friendly, programmable waveform generator controlled through the User-Interface Application Software running on a Windows-based computer system (not included). The fusion chamber uses coaxial electrodes designed for optimal electric field stimulation, independent of bath height. In this way, pulse parameters defined with the low volume optimization chamber are directly applicable for the large volume production chamber. The optimization chamber includes a transparent bottom for microscope viewing during the process optimization. BTXpress Cytofusion medium is a specially formulated, low conductivity solution for robust cell fusion efficiency.

The Hybrimune boasts a gradual increase in AC amplitude to compress the cells for maximal cell-cell contact. The DC pulse is then applied. The researcher has the option of doing multiple pulses of different voltages and duration if required. A final AC waveform holds the cells in place and stabilizes the fusion as the force is gradually reduced. The waveform generator is fully-programmable for pulse parameter optimization to maximize efficiency and cell viability.

A computer is required for the application software but is not included in the system.

The Hybrimune is intended For Research Use Only.  Not for use in diagnostic, pre-clinical, or clinical procedures.
