MCF‐7, SK‐BR‐3, MDA‐MB‐231, and MDA‐MB‐453 cell lines were obtained from Shanghai Cell Bank. All cells were cultured in RPMI‐1640 medium (Invitrogen) containing 10% FCS (Invitrogen), 100 IU/mL penicillin, and 100 μg/mL streptomycin (Sigma‐Aldrich). The cells were grown in sterile culture dishes at 37°C in a 5% CO2 atmosphere and passaged every 2 days, using 0.25% trypsin (Invitrogen) for cell detachment. All cell lines were authenticated using short tandem repeat DNA profiling.

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.
