what is the tecnique used for pharmacogenomics?

Pharmacogenomics is how an individual's genetic inheritance affects the body's response to drugs, the techniques would be spectroscopy, H.P.L.C. and E.C.P.L.

You'd probably also want to genotype the patient surely?...using RFLP or some other PCR based technique that would detect a polymorphism? It's individual polymorphisms that dictate drug response...so genotyping is the key.

Yes E.C.P.L. and also to develop in vitro tests to link genotype with phenotype.

this is the field my s.o. is pursuing currently. . . interesting career to say the least.

Hm. You have to be careful where the drug comes from, too. Generic industry is not so big after all.

In addition the new focus is on gene chip and microarray. This is because there can be hundreds of genes involved in an individuals response to a given drug and/or disease. While the analysis becomes difficult, these techniques allow a scientist to survey a much larger number of genes.
