Electro Cell Fusion Advantages v PEG
- Greater control on the fusion
- Double/triple efficiency compared with PEG
- Electro cell fusion results are more stable
- No Toxicity
- Reproducibility not dependant on Researcher Skill
To ensure accurate and reproducible cell fusion it is essential to align the
target cells prior to the fusion event. If the ion concentration of the buffer
is too high, ions will cause a water stream which will disturb the cell
alignment (pearl chain). Uniquely, the LF201 enables the researcher to
measure the resistance of the buffer prior to cell fusion and ensure the
correct ion concentration for exact cell alignment (in all experiments).
This greatly enhances reproducibility.
AC / DC Switching Time
The AC current is used to make a pearl chain (line of cells). For effective
cell fusion, it is imperative that the DC pulse is applied immediately after
the AC pulse and when the target cells are still actually in physical contact.
With the LF201, the switching time from AC pulse to DC pulse is
less than 5Ásec.
Two Kinds of DC Pulse Outputs
The LF201 offers two possible DC pulse modes. A positive (+) square wave
or a bipolar (+/-) square wave. The first is a single direction pulse and in
the other the pole of the DC pulse is switched to the opposite polarity
during pulse delivery.
There are two different types of post fusion AC current. One, a standard
Sine Wave (constant amplitude). The other, a Fade Wave (gradually
DC Pulse Output
The LF201 allows the researcher to output the DC pulse either
automatically or manually. The automatic output mode facilitates routine
work. The manual output mode enables the researcher to apply a DC
pulse while using a microscope - this is particularly useful when working
with unfamiliar cells and during nuclear transplantation.
The LF201 can be controlled via Microsoft Windows compatible software
where a cell fusion program can be entered and edited through a PC.
Each program can generate a text file capturing details such as experiment
time/date, resistance data etc..
