cDNA versus oligonucleotide array

[summer]

I am looking for information about oligonucleotide array, but i can not find any decent ones. What i get is only about cDNA array. Does this mean that cDNA array is more used and popular than oligonucleotide array? Anyone has any good and useful links about oligonucleotide microarray?

Besides i will use Human 35k oligonucleotide microarray. Has anyone used this before?


Thanks!
