RS/tRNA Additional Notes
This RS is more specific than pAzfRS2.t1, however, that RS/tRNA pair is much more efficient and thus its use instead of this system is recommended.
When tested with pAzF incorporation in Hemoglobin, a purified yield of 2mg/L. Electrospray-ionization ion trap mass spectrometry confirmed the incorporation of pAzF while also showing no presence of natural amino acid or reduced azide, showing high fidelity and stable incorporation ability of the system.
