      I am trying to perform electroporation on many kinds of mouse cell-lines by using Bio-rad electroporator.
      I can find protocol here and there such as literatures and Bio-rad websites.
      However it seems that there are many different kinds of protocols for even a single cell line.
      What is more confusing me is the uses of 2-mm and 4-mm cuvettes.

      I thought that 2-mm is for fungus and 4-mm is for mammalian cells.
      But some protocols use 2-mm and some uses 4-mm for the same kind of cells, of course with different parameters.

      Is there a formula I can use to convert parametesr for 4-mm cuvette to 2-mm cuvette?

      Thank you.

      Hi Evilid – It is quite easy to compare protocols actually: you always need to operate in terms of field intensity. Field intensity=Voltage/Gap size of your cuvette in cm (0.2 or 0.4 in your case. For mouse cell lines aim for 500 V/cm or 100V for 0.2 cm cuvette and 200V for 0.4 cm cuvette. This is a good start. Use 500 uF or 960 uF capacitance setting for mammalian cell lines.

      Good luck,

      Hi Tom – Vitamin D does NOT work well for THP-1. You need to use Retinoic Acid at 10 nM or more for 72 h to differentiate THP-1 cells. Large proportion of cells (up to 90%) will die if the protocol is working. Cell will be phagocytic for 3 u latex beads.

      Another option is Mono Mac 6 cell line which is phagocytic right out of the tube. I have not tried it because license to use it is quite expensive for a company, but for academia it is free from the German Collection of Microorganisms and Cell Cultures:

      Good luck, feel free to contact me if you have any questions.

      I can’t find any information about Electroporation. Give me some useful links where I can learn throughly about it.

      Thanks in advance!!!
