how to find 16srRNA sequences? - (Nov/30/2011 )

I want to do test 16srRNA of certain bacteria.

Where can I find the sequences of bacteria 16srRNA? Is there special database?

And are there special tricks for designing their primers?

Thanks very much!

I will do Real-Time PCR.

You can also search NCBI Gene database to find the gene for your organism, and then the actual nucleic acid sequence
