Check if the same lab product or an alternative is used in the 5 most similar protocols
MDA-MB-231 was kindly provided by Dr. JS Nam (Gwangju Institute of Science and Technology [GIST], Korea). αTAT1 KO MDA-MB-231 cells were generated using the CRISPR-Cas9 system as described in a recent paper (Ko et al., 2021 (link)). Briefly, Lentiviral particles expressing a guide sequence (5’-CATGAGTCTGTGCAACGCCA-3’) targeting Atat1 were produced by transfection of HEK293T cells with lentiCRISPR v2 plasmid, psPAX2, and pMD2.G using polyethylenimine for 48 h (Oh et al., 2017 (link)) MDA-MB-231 cells transduced with the lentivirus were selected with puromycin (1 μg/ml) for 2 weeks. Hs578t was purchased from the Korean Cell Line Bank. All cell lines were cultured in Dulbecco’s modified Eagle’s medium (DMEM; Gibco, USA) with high glucose, 10% fetal bovine serum, 100 unit/ml penicillin, 100 μg/ml streptomycin, and 250 ng/ml amphotericin B (Gibco) in a humidified incubator at 37°C and 5% CO2. All cell lines were confirmed not to be infected with mycoplasma using e-Myco VALiD Mycoplasma PCR Detection kit (iNtRON, Korea).

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.
