Backbone
Clone pleP, Gal4, Gal80 and TH
Gal4 (2646bp) integrated with UAS-Gal4 system, and pleP (452bp) and Gal80ts (1311bp) are from the genome of Drosophila melanogaster integrated with a mutant Gal80ts. Because of the repetitive sequence on the TH, it is difficult to clone so we order the synthetic pUAST (double digestion with EcoRI and XbaI)-TH from GENEWIZ®.
Digest pUAST-3xHA
For constructing the plasmid pleP-Gal4 and pleP-Gal80ts, avoiding the influence of UAS on the backbone we should remove it. We remove UAS by BamHI digestion.
Assembly
To assembly the digested backbone and fragment. We take two ways: to insert a new MCS into the backbone (done), then use a method of double digestion to insert two fragments one by one (failed), or to single digest, then use seamless cloning to insert two fragment together (success).
A) To insert a new MCS into the backbone (done), then use a method of double digestion to insert two fragments one by one (failed)
1. Transform backbone with a new MCS
2. BglII digestion to insert pleP (done)
3. pUAST-new MCS-pleP digestion (done) to insert Gal4 and Gal80ts (failed)
B) To single digest, then use seamless cloning to insert two fragment together (success)
1. BamHI digestion (2 done)
2. Seamless cloning to insert two fragment together (done)
We have done the enzyme digestion to verify them
