IMAGE DIFFERENTIATED MULTIPLEX ASSAYS FOR MULTIPLEX DETECTION OF DNA MUTATIONS

摘要

Provided herein are methods and kits for detecting the presence of DNA mutations in the KRAS, BRAF, CTNNBl, and APC genes. The methods and kits employ microcarriers, each with a probe specific for a DNA mutation in the KRAS, BRAF, CTNNBl, or APC gene and an identifier unique to the probe sequence. Upon isolation and amplification of DNA from a sample, hybridization of amplified DNA with a probe, specific for a DNA mutation, that is coupled to a microcarrier indicates the presence of the DNA mutation in the sample. Since each microcarrier can be identified through detection of the identifier, multiplex screening assays for multiple mutations in each of the KRAS, BRAF, CTNNBl, and APC genes are provided.
