Establishing LVRN-Transfected Swan71 Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
The human acute monocytic leukemia cell line THP-1 (RRID: CVCL_0006) was purchased from ATCC. To activate THP-1 cells, we added Phorbol12-myristate13-acetate (PMA, Sigma-Aldrich) and cultured them for 48h. Swan71 (RRID: CVCL_D855) was gifted by Prof. Mor G, which is human telomerase reverse transcriptase-transfected immortalized first-trimester trophoblast cell line.18 (link) Both cell lines were authenticated by STR profiling.
To establish LVRN-transfected Swan71 cells (Swan71_LVRN), hLVRN-His cDNA was inserted into pTargeT vector (Promega). Then, r-LVRN-His/pTargeT (500 ng) was cleaved and linearized with Psp1406I and transfected into Swan71 cells using FuGeneHD (Promega). After 48 h of gene transfer, a stable expression strain was established and isolated using a medium containing 500 μg/mL G418. For controls, the non-inserted pTargeT vector was transfected into Swan71 cells (Swan71_NEO). Cell lines were maintained at 37°C under 5% CO2 in RPMI (Nacalai Tesque, Kyoto, Japan) supplemented with 10% FBS (Sigma-Aldrich), 100 g/mL streptomycin, and 100 IU/mL penicillin. Mycoplasma infections were detected regularly, and all experiments were performed under mycoplasma-free conditions.

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.
