Profile
Name: TPH
Base Pairs:1641bp
Origin: Synthetic
Properties: the coding sequence of tryptophan hydroxylase (TPH).
Usage and biology
TPH catalyzes the L-tryptophan to the 5-hydroxy-L-tryptophan
Experiment Data
Acquisition of linearized vectors pTRC99K and inserts TDC-TPH
Line 1: pTRC99K-vector, control plasmid
Line 2: linearized pTRC99K-vector, correct
Line 3: the PCR product of TDC, correct
Line 4: the PCR product of TPH, correct
Line 5: the over-lap PCR product of TDC-TPH, correct
Line 6: the over-lap PCR product of TDC-TPH, correct
Gel electrophoresis of recombinant plasmid pTRC99K- TDC-TPH shows that the size of pTRC99K-TDC-TPH-2 is correct.
In theory, the expression of inserted coding sequence must be induced by IPTG. However, experiment data shows that protein can express successfully regardless of whether there is IPTG induction.
Lane 1: Culture supernatant with induction (40 μL)；
Lane 2: Culture supernatant without induction (40 μL)；
Lane 3: Without samples
Lane 4: Supernatant of cell lysate with induction (40 μL)；
Lane 5: Supernatant of cell lysate without induction (40 μL)；
Lane 6: Pellet of cell lysate with induction (40 μL)；
Lane 7: Pellet of cell lysate without induction (40 μL)；
Lane 8: Supernatant of cell lysate with induction (20 μL)；
Lane 9: Supernatant of cell lysate without induction (20 μL)；
We got two bands 43.53kDa (TPH) and 53.55kDa (TDC) in both supernatant of cell lysate and pellet of cell lysate. These results suggest that TPH and TDC proteins can be expressed successfully regardless of IPTG induction.
