Has anyone had experience with transfection in CCD 841 CON cells? . I have tried transfecting pEGFP-C1 plasmid using PE-I protocol and have had low expression ( less than 1% of positivity). Any suggestions are welcome.
This larva was captured using a plankton net in the Persian Gulf during the summer. I believe it may be a Facetotecta nauplius.
