There is also a large gap between the oligos with only a few bases added and those with 30+ bases added.

CU 1017 TdT.png

As seen from the polyacrylamide gel shown above, the TdT enzyme expressed in the Rosetta cells using our genetically engineered plasmid works as intended; base pairs are appended to oligos by the enzyme. However, there is a difference between the activity of our enzyme compared to the commercially obtained TdT. The majority of the oligos have only a few base pairs added by our expressed TdT while the lane of the commercial TdT is a smear of oligos, suggesting the commercial TdT has a greater reaction rate. But it can also be attributed to the fact that the 0.5 U/μL concentration of our expressed TdT is an overestimation. The TdT concentration of the reaction with our expressed TdT is less than that of the commercial TdT.

There is also a large gap between the oligos with only a few bases added and those with 30+ bases added. This suggests that our expressed TdT has a higher processivity than that of commercially obtained TdT. This might be due to subtle sequence differences such as the His tag on our TdT sequence.
