Morpholino electroporation into a protist

Morpholino oligos electroporated into trypanosomes knocked down expression of an argonaute family gene, TbAGO1, as shown in a new paper by Shi, Tschudi and Ullu from Yale University Medical School. To overcome the delivery barrier of these protists, concentrated oligo solutions were used: Morpholinos were electroporated from solution at 500 microMolar concentration instead of the more usual 10 microMolar concentration used for cell cultures. Inhibition of >80% of the incorporation of 35S into new TbAGO1 protein was measured in antisense-treated protists compared with protists treated with negative control oligos.
