Design Notes
We design the cassette for TA cloning in such a way that the distance between the two Eam1105I (AhdI) recognition sites is minimal. After digestion, the fragment is way too short to be recovered efficiently by the commonly used kits. This eliminates the need for gel purification and simplifies the entire cloning procedure. Moreover, this fragment does not have stop codons in any of its 6 RFs so even if it stays and gets re-ligated in a reversed orientation, the blue-white screening procedure will recognize these clones as empty (blue). Last but not least, if a single T is added to the 5' ends of the used primers that will result in a stop codon formation after ligation. This improves the resolution of the screening procedure since now positive clones are extremely unlikely to develop a red color.
We located a flexible linker between the T-vector module and the mRFP1 CDS (https://pubmed.ncbi.nlm.nih.gov/10404163/). The EcoRI recognition site found inside the linker's sequence was mutagenized.
The AhdI restriction site in the CDS of mRFP1 was removed via the introduction of a silent mutation D59D.
