syIs536 [15xUAS::lin-3c::SL2::GFP::let-858 3'UTR + ttx-3p::RFP + 1kb DNA ladder (NEB)] cGAL effector for epidermal growth factor

Bacteria. E. coli harboring the plasmid PB255, which uses the lin-31 promoter variant to express the lin-31::VP16 chimeric gene. It is particularly useful for the expression of heterologous genes in the vulval precursor cells. PB255 possesses three main components : an enhancer, a promoter region, a multi-cloning site (MCS), and a 3' UTR derived from the unc-54 gene. [CGC note: The plasmid in this strain was constructed from pBS II KS(+) and is likely Amp-R, but Amp-R has not been confirmed]. Biosafety Level: BSL-1.
