The U87MG is a cell line derived from a human glioblastoma, a type of brain tumor. It is a widely used model in cancer research and drug discovery. The U87MG cell line exhibits characteristics typical of glioblastoma cells, such as rapid growth and high invasiveness. Researchers utilize this cell line to study various aspects of glioblastoma biology and to test potential therapeutic agents.

Two human cell lines (U87MG, U251) were obtained from the Cell Bank of Type Culture Collection of the Chinese Academy of Sciences (Shanghai, China) and used within 6–8 months. All cells had tested for mycoplasma contamination and were cultured in high glucose Dulbecco’s modified Eagle’s medium (DMEM, Gibco, USA) with 10% fetal bovine serum (FBS, Biological, Industries) and 1% penicillin-streptomycin (10378016, Invitrogen, USA) at 37 °C with 5% CO2. Plasmids and siRNA were transfected into cells with Lipofectamine 3000 (L3000-008, Invitrogen, USA) according to the manufacturer’s instructions. lentivirus particles were directly added into target cells with 4 μg/ml polybrene (GM040901, Genomeditech, Shanghai, China). After two rounds of infection, cells were selected for at least 7 days by adding 10 μg/ml blasticidin (B9300, Solarbio Life Sciences, Beijing, China) or 1 μg/ml puromycin (P8230, Solarbio Life Sciences, Beijing, China) into the growth medium.

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.
