Cry4Ba (HA tag) + deGFP Device

PR1 - RBS - Cry4Ba (HA tag) - RBS - deGFP - T500 Terminator

This plasmid was planned on a pBEST plasmid backbone. It contains larvicidal activity, as it containing toxic subunit of the bacillus thuringiensis israelensis (BTI) pBtoxis plasmid which is toxic to mosquitoes larva.

The plasmid was constructed using gibson assembly, then was incorporated into E.coli BL21 and DH5a using Heat shock, and into serratia marcescens 274 using electroporation.


Characterization

Western of Cry4Ba subunit with anti-HA antibody. proving the translation of the toxin subunit on the plasmid.

Experiance

In our plasmids, we placed the deGFP closer to the terminator. The presence of the GFP signal proves the expression of the previous subunits on the plasmid and it allows the detection of the transgenic bacteria easily (in mosquitoes)

Here we can see the level of fluorescence of liquid starters from Serratia expressing the different type of plasmid we created. (BBa_K2938014, BBa_K2938015, BBa_K2938016).

Fluorescence levels of Serratia expressing our different plasmids

We made toxicity assays, In order to check how effective and toxic are our plasmids. We hatched mosquitoes untreated eggs in water containing Serratia bacteria expressing the different plasmids. Then we counted the live larva 48 hours after treatment.


Toxicity assay results, Our plasmids show larvicidal activity
