method for analyzing a DNA sample, method for preparing a set of coded DNA analysis matrices, DNA analysis reagent, DNA analysis multiplex reagent and DNA analysis kit

摘要

Encoded bead multiplex assays for chromosomal gains and losses are provided that provide the benefits of complex, large template DNA sources, such as BAC DNA, as the probe material without bead networking or other assay performance problems. Reagents for assaying DNA are described herein which include a plurality of encoded particles having attached amplicons amplified from a template DNA sequence. Each individual attached amplicon includes a nucleic acid sequence identical to a random portion of the template DNA sequence, wherein the amplicons together represent substantially the entire template DNA and wherein the nucleic acid sequence identical to a random portion of the template DNA sequence of each individual amplicon is shorter than the entire template DNA.
