Change for plant expression

Postby mehdi71000 » Thu Jun 14, 2007 8:35 pm

Hi every one
Can, if so how this plasmid be changed so the gene can be expressed in 1 small animals, 2 plants, 3 insects?

change the regulation region... to a promoter sequence that is only active in (unique-to) small animals, plants or insects ...

not sure if there is a simpler solution?

Thanks mate is there a way you can guide me. like what enzymes do I need and when and how to use them?

u need a bunch restriction enzymes, and u need the exact sequence of the plasmid for the restriction sites. Go with eukaryote plasmids.

Yep, in fact it is more complicated than just changing the promoter, because if you want to transfer your plasmid in a eucaryote you also need to insert an eucaryotic origin of replication, otherwise it will not be able to be replicated.

What you want might be what is called a shuttle plasmid, one that contains both origin of replication, and usually a promoter only for the final host (it is easy to transfer modify and propagate the plasmid in bacteria and then you can transfer it in plant/insect/mammalian cell when you want to express your gene.

Thanks guys. I found this site it makes custom Dna
They have a software that allows you to make a vector and they will make it for you afterwards but I bet its going to be very expensive. Here is the link . http://www.dna20.com/genedesigner/GD_download.html

Is this plasmid any good for plants (pblu)?
Thanks

One more thing.
Can I remove the gene from ecoli that is responsible for the translation in ecoli and add that to the plant so the plant can translate the plasmid?
