pmyo2::GFP pmyo3::unc-60::RFP pmyo3::unc60::GFP These 3 constructions xere microinjected in worms under the microscope. Pmyo2::GFP is used as a brenchmark in order to know if our worms were well injected. The promoter pmyo2 is tissue specific, it allows the expression of the gene myo-2 in the pharynx of the C.elegans. Thanks to the green fluorescent pharynx, we can screen transformed worms from non transformed worms. The two others constructions, pmyo3::unc-60::RFP and pmyo3::unc60::GFP, will allow us to see how the two different isoforms unc-60A (RFP) and unc-60B (GFP) are expressed in the body wall muscle. Here are a few pictures about what we obtained under the microscope.
