Abstract: The invention provides method for genotyping specific sets of polymorphisms in a single multiplex reaction. The polymorphisms are selected to be of interest in detecting genetic variation that alters individuals' metabolism, distribution, extretion and transport of pharmacological compounds. In preferred aspects the genotyping employs a multiplex hybridization-based assay. In some aspects combinations of methods are employed to allow the combination of polymorphisms to be interrogated. The invention also provides nucleic acid standards for validating the performance of such hybridization-based assays.

Abstract: A method of using micromechanical devices as sensors for detecting chemical interactions between naturally occurring bio-polymers which are non-identical binding partners is provided. The method is useful whether the reactions occur through electrostatic forces or other forces. Induced stress, heat, or change in mass is detected where a binding partner is placed on a cantilever for possible reaction with an analyte molecules (i.e., a non-identical binding partner). The method is particularly useful in determining DNA hybridization but may be useful in detecting interaction in any chemical assay.
