A Revolutionary Single-Cell Electroporator
The Axoporator® 800A electroporator, the world's first commercially
available single-cell electroporator, represents the convergence of biophysics, cell biology and molecular
biology. This micropipette-based delivery system uses voltage pulses to cause the transient formation of
membrane pores through which flow impermeant molecules and/or ions. The mechanism is the same as that used
for the bulk electroporation of suspended cells—dielectric breakdown of the membrane by a voltage
pulse—however, single-cell electroporation offers distinct advantages over bulk electroporation:
Individual cells can be targeted for specific modification. Whether you're using isolated cells, tissue slice or an intact preparation, this technique allows you to focus on an individual cell.
Precise regions of the cell can be selectively targeted. Apical vs. basal, neurite vs. axon, animal vs. vegetal pole—single cell electroporation allows you to focus on very specific regions of the cell under study. Large, isolated, and intact organelles are also suitable for single-cell electroporation.
Only minute volumes are required for electroporation. This helps preserve expensive and rare molecules.
Very high rates of survivability, 80% on average. Cells better tolerate the intervention because only a small portion of cell membrane is involved with the voltage-delivering micropipette. Thus a cell can be electroporated more than once with different genes.

Documented Success
The Axoporator 800A electroporator was developed with advice from and tested by the pioneers in
single-cell electroporation. Their successful protocols are documented in the user manual and
application notes that accompany the Axoporator 800A.
The Axoporator 800A electroporator combines two of Axon's time-proven strengths—patch-clamp
technology and precise waveform generation. An LCD, push buttons and knobs comprise the intuitive
user interface. All pulse and train settings as well as pipette resistance and power readings are
available on the LCD display. If desired, the micropipette voltage and current can be recorded from
BNC connectors. Three different pulse types are provided, all of which can be run in either polarity
and in trains. These include:
Rectangular "square"
Bipolar
Bilevel—a special pulse that has been demonstrated to effectively and efficiently deliver genes as large as 14 kb into the cell.
Flexible Control and Design
Although designed for convenient stand-alone use, an external waveform generator
such as pCLAMP software with a Digidata 1322A can act as the source of the pulse command.
Once configured, the Axoporator 800A can be activated by a single press of a button. Alternatively,
activation can occur through a supplied foot switch or an external trigger (TTL), so both hands are
available to control the microscope and the micromanipulator. A Sync Output BNC can be used to
synchronize an optional recording system.
It has been our experience that researchers are forever finding unconventional and clever ways to use
our products—hence Axon's tradition of flexible design. Axoporator 800A incorporates two very important
features in anticipation of future applications:
A "Factory Only" input is provided for downloading firmware upgrades as the field of discovery evolves.
The voltage range extends to 100 V, because the optimal voltage for single-cell electroporation can be several tens of volts in some preparations.
The standard AP-1A-1MU headstage can pass current up to 100 µA. An optional AP-1A-0.1MU headstage can
pass current up to 1 mA.
Added Convenience
To aid in positioning the micropipette, a built-in audio monitor changes tone as you near a cell
and make contact. This audio monitor, together with the resistance display, provides a useful tool
for blindly searching out cells in tissue slice.
Tracking the number of electroporation commands is a snap, as there are both automatic and manual counters.
The small footprint of the Axoporator makes for easy positioning near the microscope.
Ready to Use
No computer necessary. A microscope, a micromanipulator and a source of micropipettes are all
that are needed to complete the system.
