YES.
The N-terminal methionine of the product synthesized by PUREfrex^® is formylated. And they are not deformylated during/after translation.

However, depending on the amount of synthesized protein, the formyl donor may be depleted and some non-formylated proteins may be present. PUREfrex^® proceeds with the translation reaction even if the N-terminal methionine is not formylated, but synthesis efficiency may be affected depending on the protein to be synthesized.
