Researchers detail methods behind bitopic BCR::ABL1 kinase inhibitor study

A methods disclosure describes how researchers sourced and synthesized kinase inhibitors—including ponatinib, asciminib, imatinib, dasatinib and osimertinib—and cultured K562 and HEK293T cell lines to test them. The report details engineered K562 stable lines carrying BCR::ABL1 mutations, created via enzymatic mutagenesis of a pUltra vector, used to evaluate inhibitor activity in cell-based assays.

New 'Prime Assembly' method enables large-scale gene insertion using prime editing

Researchers used K562, Jurkat and HEK293T cell lines to test a genome-editing technique called prime assembly, which combines prime editing components (PE7 or PEmax) with pegRNAs and various DNA donor templates to insert genetic sequences at targeted genomic sites. The team tested donor formats ranging from short synthetic single-stranded DNA to large double-stranded DNA fragments up to 12.1 kilobases, optimizing nucleofection conditions for each donor type.
