Estrov, (M.D. Anderson Cancer Center, Houston, TX). TKI-resistant BV173 cells were generated by step-wise selection in the presence of increasing concentrations of imatinib, which induced the outgrowth of cells with the BCR-ABL1 T315I mutation. Experiments were performed on cell lines cultured for less than thirty passages. Mycoplasma was tested monthly following an established procedure (30 (link)). Cell lines were routinely authenticated by monitoring B-cell markers and BCR-ABL1 isoform expression.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
