transient transfection with luciferase system

Postby elke » Tue Jul 10, 2007 10:45 am

Hi,

I do now transient transfection with the promega luciferase sysyem (FireFly and Renilla Luciferase) and would like to know how long the constructs are in the cells. Because I learnt that 2 days after transfection the cells "skip" the plasmid but I would do longer treatments and would like to see if there is a time dependency. But if the cells loose the plasmid before I measure the luciferase I'm not able to see any effect...
Hm, maybe someone has a few experience with this topic or is very smart and can help me?!

Thanks a lot in advance,
Elke

hello.
In our lab we are doing Luciferase assay....
one option is to do double transfection of your plasmid....
for example: firstly you do transfection and next day after that or two days after first trasfnection you can do transfection again...
