Designing PCR primers-How to check them?

[Peter---bkxo at musicb.mcgill.ca]

I have designed a set of primers for amplification of a 300 bp ds DNA 
fragment from human genomic DNA.  	

I would like to check these primers for any complementarity they may 
have to repetitive sequences found in the human genome.  I am 
concerned that the presence of such complemantarity would result in 
non-specific amplification.

Is there a database I can access to perform this search? If yes, how?

I am interested to know how other people go about checking primers 
which they have designed before actually ordering them.

You can reach me at   bkxo at musicb.mcgill.ca     or post a note here.  

Thanx.
