Biobricked pCS2+ plasmid for frogs and chicken

This plasmid is a biobricked version of the standard plasmid pCS2+. This plasmid is made of a bacterial ampicilin reststant 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.

This plasmid is ment to be micro-injected in frog eggs or chicken eggs for a transcient expression of the protein at the early ages of development of the embryo. This plasmid does not replicate, so it gets diluted and degraded as the animal grow, leaving no chance for DNA propagation to the breeding.

To use this plasmid, you simply have to insert your gene between the EcoRI and PstI site. It is better to add a kozac sequence in front of your gene to enhance its expression.

This plasmid contains the standard registry insert J04450 as a negative cloning control. This plasmid was characterized. The insert J04450 is replaced by the BioBrick K812031 (sfGFP. This new plasmid (K812133) express sfGFP into Xenopus:

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. Sequence and Features
