MTT method
We have used 540nm for MTT reading and I think it doesn't meter which type of cells are you using.
I also used 540 nm for MTT assay and this assay is not cell line specific.
540 or 560 nM is the most efficient,
i always substract a 720nM readout as a background control.
We work with HeLa cells and read absorbance at 570 nm for MTT. It is not cell line specific as they have said.
We utilize an immortal endothelial cell line and various agonists to observe their effects on Src phosphorylation. However, our protocols seem to induce high basal levels of Src phosphorylation....

In my new research, about TiAlN thin films, i constantly use the word "shift". I would like to know if i can write "displacement" as a synonym, with the intention to not repeat the words.
