Biobricked pCS2+ plasmid for frogs and chicken

This plasmid is a biobricked version of the Xenopus standard plasmid pCS2+. This plasmid is made of a bacterial ampicilin resistant backbone, with a universal CMV promoter. The Biobrick site is surrounded by a a 5'UTR expression enhancer, and a ploy-A tail with a SV40 3' UTR that tnhance the stabilisation of the mRNA and the expression of the protein. pCS2+ can be used as expression vector in a wide variety of mammalian and avian cells. It is also functional in zebrafish embryos.

This plasmid is ment to be micro-injected in frog eggs or chicken eggs for a transient expression of the protein at the early ages of development of the embryo. This plasmid does not replicate inside the cells, so it gets diluted and degraded as the embryo develop and its cells multiply. And as long as there are no sequence homologies with the host genome, integration through recombination is null, leaving no chance for DNA propagation to the breeding.

To use this plasmid, you simply have to insert your gene between the biobrick prefix and suffix sites. It is better to add a kozac sequence in front of your coding sequences in order to enhance its expression.

This plasmid contains the standard registry insert J04450 as a negative cloning control.

This plasmid was characterized with different reporters.
For example, the insert J04450 is replaced by the BioBrick BBa_K812031 (sfGFP. This new plasmid (BBa_K812133) express sfGFP into Xenopus:
perdu

The expression of sfGFP is present only in one out of the two embryo/tadpole. sfGFP is present only in few tissue as others reporters. sfGFP is expressed in tail's muscles and branchial basket for this tadpole. After injection of this plasmid into Xenopus it does not diffuse in the eggs, and the plasmid express sfGFP in few different tissues.
