Splice Variant Analysis (FISH)

Alternative splicing is a fundamental regulatory process of gene expression that allows generation of multiple mRNA isoforms from a single gene, which plays significant roles in human disease, particularly cancer and neurological disorders. Splice variants that are found predominantly in tumors have clear diagnostic value and may provide potential drug targets. And understanding the process of aberrant splicing and the characterization of the splice variants may prove curcial to our understanding of malignant transformation.

Currently, there is only a limited number of methods have been explored to detect RNA splicing variants. Detection of short isoform-specific sequences requires RNA isolation for PCR analysis – an approach that loses the reginal and cell-type-specific distribution of isoforms. Having the capability to distinguish the differential expression of RNA variants in tissue is critical because alterations in mRNA splicing and editing, as well as coding single nucleotide polymorphisms, have been associated with numerous cancers, neurological and psychiatirc disorders. With years of experience in Fluorescence in situ hybridization, Creative Bioarray can offer a highly sensitive single-probe FISH/ISH approach that targets short exon/exon RNA splice junction using single-pair oligonucleotide probes. The detection we provide would ensure accurate detection of the mature mRNA variant.

Figure 1. Mouse ErbB4 isoform detection. The specificity and sensitivity of single-pair probes targeting exon-exon boundries were determined by hybridizing sections from WT mice. Probes targeting the exon 1/2 (pan1/2) and exon 2/3 (pan 2/3).
