Vector recommendation for RNAi in Drosophila

[M B]

Hello,

I want to make an RNAi construct to knock down a gene in vivo in Drosophila.

My insert is long double-stranded RNA (dsRNA), not a short hairpin. I need germline expression, so I require a vector that supports long dsRNA and contains UASp. Do you know which vector is best for this purpose?

Thank you,

Mori
