Because of its long curing time of as much as ten hours, it is ideal for woodworking applications, which require unhurried and careful assembly. Polypropylene is often preferred over polyethylene because it has a higher melting point. Real-time RT-PCR was used to quantitatively analyze the expression of exogenous p53 which indicated that MV when combined with FEO would upregulate the P53 expression in both breast cancer cell lines.
