Dose-Response Assay for Neratinib Resistance

Check if the same lab product or an alternative is used in the 5 most similar protocols

For dose-response assays, parental and neratinib-resistant cells were seeded in 12- well plates; 24 hr later, cells were treated with DMSO or increasing concentrations of neratinib (11 doses ranging from 0.1 nM to 10 μM, 3-fold dilution). Six days later, cells were trypsinized and counted using Z2 particle count analyzer (Beckman Coulter). GraphPad Prism 6 software was used to plot dose response curves and determine GI₅₀ concentration.

Strains, media, and growth conditions used in this study are listed in Supplemental Table S1. If required, antibiotics, vitamin B₁₂ (cyanocobalamin), and thiamine were added to the medium at concentrations indicated. Algal culture density was measured using a Z2 particle count analyzer (Beckman Coulter Ltd.) and optical density (OD) at 730 nm was measured using a FluoStar OPTIMA (BMG labtech) plate reader or a CLARIOstar plate reader (BMG labtech). Bacterial growth was recorded by measuring OD₅₉₅.

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.
