To develop a practical and accurate genetic assay for verifying the identity of tumor cell lines and clinical tissue specimens during routine laboratory investigations.
Designed an empirical genetic assay, termed the SNP panel identification assay (SPIA), utilizing 34 informative single nucleotide polymorphisms.
Engineered the protocol for regular laboratory compatibility to monitor cell line integrity and tumor specimens over extended experimental timelines.
Established a 34-SNP genotyping panel capable of definitively resolving cell line identity to prevent cross-contamination and misidentification.
Provided an accessible quality-control alternative to broad genomic assays to resolve pre-analytic identity errors reported across the scientific literature.
