The inducible lac promoter + LTNF15 was PCR amplified using master mix, DI water, and LTNF primers we got synthesized. We denatured the construct at 95˚C for thirty seconds, annealed at 62˚C for thirty seconds, elongated at 72˚C for thirty seconds and repeated the cycle 25X. Due to the size of the peptide we initially found it difficult to gel extract and purify the inducible lac promoter + LTNF15. To bypass this, we opted to skip the gel extraction step, and directly digest the PCR product with EcoRI and PstI. We had issues with ligating our part into an empty pSB1C3 vector. So we digested RFP in pSB1C3 with EcoRI and PstI and used that vector. Inducible lac promoter + LTNF15 was then ligated with a pSB1C3 vector and then transformed into DH5α competent cells using the heat shock method. One hundred micro liters of the transformation was spread on a LB plate with 35ng/uL chloramphenicol and incubated for 24 hours at 37˚C. The colonies that grew were picked, dipped into a colony PCR reaction containing master mix, DI water and VF VR2 primers and then inoculated in 5mL of LB broth with 5uL of chloramphenicol overnight. A colony PCR gel was run to check which colonies had a transformed recombinant plasmid. A QIAgen miniprep was done to extract the plasmids. Diagnosis gels were run to check if the part was successfully cloned into the vector.

Applications of BBa_K1915003




The inducible lac promoter + LTNF15 was PCR amplified using master mix, DI water, and LTNF primers we got synthesized. We denatured the construct at 95˚C for thirty seconds, annealed at 62˚C for thirty seconds, elongated at 72˚C for thirty seconds and repeated the cycle 25X. Due to the size of the peptide we initially found it difficult to gel extract and purify the inducible lac promoter + LTNF15. To bypass this, we opted to skip the gel extraction step, and directly digest the PCR product with EcoRI and PstI. We had issues with ligating our part into an empty pSB1C3 vector. So we digested RFP in pSB1C3 with EcoRI and PstI and used that vector. Inducible lac promoter + LTNF15 was then ligated with a pSB1C3 vector and then transformed into DH5α competent cells using the heat shock method. One hundred micro liters of the transformation was spread on a LB plate with 35ng/uL chloramphenicol and incubated for 24 hours at 37˚C. The colonies that grew were picked, dipped into a colony PCR reaction containing master mix, DI water and VF VR2 primers and then inoculated in 5mL of LB broth with 5uL of chloramphenicol overnight. A colony PCR gel was run to check which colonies had a transformed recombinant plasmid. A QIAgen miniprep was done to extract the plasmids. Diagnosis gels were run to check if the part was successfully cloned into the vector.
