✦ Synopsis

RT-PCR is the method of choice for detecting BCR-ABL in CML and ALL. The three predominant mRNA transcripts found are e1a2 (in ALL), e13a2, and e14a2 (in CML and ALL). However, a number of "atypical" BCR-ABL transcripts (e1a3, e13a3, e14a3, e19a2, e6a2, e8a2, etc.) resulting from chromosomal breakpoints outside ABL intron 1 or BCR intron 1, 13 or 14, respectively, have been reported. These atypical transcripts may escape detection when using methods that are optimized to detect just the typical ones. We present here a novel, fast, and reliable multiplex PCR for improved detection of typical and atypical BCR-ABL transcripts.

## Abstract In this study, a sandwich‐type electrochemical enzyme‐based LNA‐modified DNA biosensor was developed to detect relative gene in chronic Myelogenous Leukemia first. This biosensor is based on a ‘sandwich’ detection strategy, which involves a pair of probes (a capture probe immobilized at
