Fragment of 19 was phosphorylated and then purified with DNA Purification Kit.
19 was ligated into T vectors via TA clone and transformed into E.coli via heat shock.
A colony PCR was performed with five colonies
Gel electrophoresis showed that 5 colonies were positive for insertion of 19.
Two of these colonies containing 19 were used to inoculate overnight cultures.
15 gene fragment was phosphorylated.
Plasmids containing T vector with 19(pT-19)were isolated using a miniprep kit.
Mono-restriction digest of pT-19 with stu I
The enzyme-digested product was dephosphorylation.
Dephosphorylated plasmid and phosphorylated gene 15 were connected.
Ligation product was transformed into E.coli via heat shock.
A colony PCR was performed with twelve colonies.
Gel electrophoresis showed that 2 colonies were positive for connecting the plasmid and gene fragment.
These two colonies were used to inoculate overnight cultures.
Plasmids with correct sequence of 19-15 were isolated using a miniprep kit.
Mono-restriction digest of pT-19-15 with Nru I
The enzyme-digested product was dephosphorylation.
