ChannelMAX 100A Mini
A system for both
oocyte and cell patch clamp and two-electrode voltage champ
This
patent-pending design is based on the PatchMAX 100A, but it comes
with two computer controlled manipulators. With the additional
micromanipulator, the system can do two patch clamp experiments
simultaneously, or one two-electrode voltage clamp experiment.
With this new design, the system increases efficiency, decreases
equipment cost, and saves space. As the system is controlled
by the computer, the experiment becomes less labor intensive.
Run two patch clamp experiments simultaneously
The ChannelMAX
100A Mini comes with two computer controlled manipulators, as
a result users can run two patch clamp experiments simultaneously.
Doing two experiments at the same time allows for better decision
making while doing experiments. Single channel activities are
random events. It is difficult to understand what is going on
by looking at the channel open and close, especially when you
are working on a new channel. For example, it is hard to distinguish
a channel with two open stages from two channels in the same
patch. With two patches that are treated with the same conditions
you have more information that could be critical in making the
right decisions while working on the precious seals.

High quality
patch clamp
As in the PatchMAX 100A, the ChannelMAX 100A the
patch clamp is noise free and low drift. The computer controlled
system eliminates human errors so the success rate of making
gigaohm seals using the ChannelMAX 100A is over 90%.
Run two
independent patch clamp experiments
It is very easy to change
the configuration to run two independent experiments. As shown
in the figure on the right, you can easily have two perfusion
chambers on the same setup.
Automated two-electrode voltage clamp
For the two-electrode voltage, impalement is controlled by
computer so no microscope is needed. When the electrode enters
the oocyte, the membrane potential changes and the movement
is stopped. The user can define the membrane potential threshold
and delay for the stop after the electrode enters the oocyte.
Save on equipment
cost
This system is more cost effective than a traditional electrophysiology
setup. In order to reach the same functionality and productivity
using a traditional setup, the equipment cost would be much
higher, as compared in the table below. Plus labor cost is
additional. Coming with the lower cost is also better quality.

Save space
As the system can be used for both two-electrode
voltage clamp and patch clamp, less lab space is required.
You do not need two data acquisition systems. All the data
is on one computer, so it is easy for you to compare.
Switching
between patch clamp and two-electrode voltage clamp is easy
The system is designed so that it can switch from patch clamp
to a two-electrode voltage clamp easily. With all of the adjustable
parts, the system can easily be adapted to different glass
electrode lengths and sizes, and different amplifiers.

Use
with traditional two-electrode voltage clamp experiments
It
is possible to use the ChannelMAX 100A Mini with a traditional
two electrode voltage clamp to run two two-electrode voltage
clamp experiments simultaneously.
High efficiency, less labor-intensive
As the system is automated, it is easy to run experiments in
parallel to increase efficiency. Patch clamp and two-electrode
voltage clamp should not be as labor-intensive as before. Let
the equipment do the hard work for you!
