Patent ID: 7417138

Claim:
A peptide nucleic acid (PNA) chip for determining the genotypes of mycobacterial species wherein a plurality of probe PNAs is immobilized on a plastic substrate coated with an epoxy group-containing polymer, wherein the plurality of probe PNAs comprises a probe PNA consisting of SEQ ID NO: 5, a probe PNA consisting of SEQ ID NO: 6, and a probe PNA consisting of a sequence selected from the group consisting of SEQ ID NOs: 7-28, wherein each probe PNA is immobilized in an individual spot; and wherein the mycobacterial species are selected from the group consisting of M. tuberculosis complex, MAC complex, M. fortuitum, M. chelonae, M. abscessus, M. kansasii, M. gordonae, M. scrofulaceum, M. szulgai, M. vaccae, M. xenopi, M. terrae, M. flavescens, M. smegmatis, M. malmoense, M. simiae, M. marinum -ulcerance, M. gastri, M. avium, M. intracellulae, M. genavense, and M. lentiflavum.
