cloning oligos

[Eric Daniel Slosberg]

Hello:
	Does anyone have experience/knowledge about cloning ss 
oligonucleotides into a vector.  Do I need to make a complementary oligo 
and anneal to make a dslinker?  Is it possible to just ligate the oligo 
into the vector and fill in the second strand w/klenow?  Also what 
ratio of insert:vector is needed for this type of cloning (especially if 
I make a blunt ended dslinker). Any advice can be posted on this newsgroup. 
Thanks in advance.
