Overexpression and Silencing of FLRT2 in Breast Cell Lines

Check if the same lab product or an alternative is used in the 5 most similar protocols
Normal breast cell line MCF-10A and breast cancer cell lines MCF7, T47D, MDA-MB-231, HCC38, and HCC1395 were purchased from ATCC (Manassas, VA, USA) and cultured under the optimal conditions required according to instructions by ATCC. To over-express FLRT2 in cultured cells, a recombinant expression vector containing the open reading frame was designed and constructed as an OmicsLink ORF Expression Clone (Genecopoeia, Rockville, MD, USA). Pre-designed siRNAs for FLRT2 silencing were purchased from Bioneer (Daejeon, South Korea). The most effective siRNA concentration was determined by transfecting cells with 10, 40, and 80 nM siRNA. All transfection processes were performed with Lipofectamine 2000 (Invitrogen, Carlsbad, CA, USA) by following the supplier’s protocol.

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.
