Retina – Ex Vivo EP
We recommend three possible electrode configurations for Retina Ex Vivo EP.
The retinas are dissected at embryonic stages (starting Embryonic day 12) and early postnatal for electroporation.
1) CUY700P5E and CUY700P5L
2) CUY701P7E and CUY700P5L (in some cases, a larger electrode at the bottom (positive electrode) works better).
3) CUY520P5 (See the protocol above: Chapter 19 – Analysis of Gene Function in the Retina).
Generally, we express a preference for the CUY520P5 electrode configuration because:
– it is the electrode configuration specified in detail in the publication: Chapter 19 – Analysis of Gene Function in the Retina,
.

The left eye and the optic nerve were exposed.
A small hole was made with a 31-gauge needle 0.5 to 1.0 mm The eye was then immediately grasped between tweezerz-type electrodes, with the cathode attached to the corneal electrode and the anode with the slit attached to the scleral electrode. |
Arrangement of electrodes for in vivo electroporation for RPE transfection.
(A) Tweezer-type electrodes were placed on the corneal surface of either eye of a 1-month-old Sprague-Dawley rat. (B) The current was applied with the positive electrode contralateral to the injected eye. After prior injection of plasmid DNA into the subretinal space of the right eye, this arrangement electrophoresed the negatively-charged DNA toward the RPE layer (arrowheads). |
We recommend both the CUY675P5 and CUY650P7 electrodes for In vivo/postal natal Retina EP.
However, most clients opt for the CUY650P7 configuration because it can also be used for (whole) Cultured Embryonic (and Large Tissue) EP.

Early Postnatal Mouse Eye/Retina EP
For your information:
With respect to gene delivery into Mouse Embryo Eye/Retina (and Brain) one can use the tungsten needle type electrode. However, as the mouse embryo is very small it is often hard to inject DNA into the embryo’s eye. Some clients have reported using the CUY675P5 electrode It is structurally possible to use this electrode for both Embryo (in utero) and Mouse Eye electroporation. (Please note the table below).
As one can see, however, there is a cut-out on one side of the CUY675P type electrodes. So, for this application we are not convinced that it is the optimum electrode for the application. Rather, our recommendation is for the CUY650P7 electrode. Note the attached CUY650P7 Technical Drawing.
This is the electrode most of our clients choose. It has a fully rounded set of electrode paddles and therefore covers a larger area of the target. In addition, this electrode has a much wider application range and can be used, for example, for or (whole) Cultured Mouse Embryos and Large Tissue EP. Dr. Matsuda uses the CUY650P7 electrode in his articles contained in the ‘EP with Retina’ below). Takahiko Matsuda and Constance L. Cepko Electroporation and RNA interference in the rodent retina in vivo and in vitro PNAS, Volume 101, Number 1, Pages 16-22, 6 January 2004 |
In Utero Embryo EP
The standard electrodes for In Utero Embryo EP are CUY650P3 and CUY650P5, which have circle electrodes without a cut. |
Mouse Embryo – Cornea
For gene delivery into Mouse Embryo – Cornea we recommend:
– CUY671P1 or Technical Drawing: CUY671P1 – CUY670 Technical Drawing: CUY670 Protocol Recommendation: – ‘Electroporation and RNA interference in the rodent retina in vivo and in vitro‘ – ‘Protocol for in vivo electroporation into mouse/rat retina’ – ‘Compensation by tumor suppressor genes during retinal development in mice and humans‘ For your further information, note the article titled: – ‘A role for ligand-gated ion channels in rod photoreceptor development’. In this article and ‘Electroporation and RNA interference in the rodent retina in vivo and in vitro’ above genes are transfected into mouse and rat retina. We believe that the method outlined in these articles can be applied to Gene Therapy |
