Summary
Lactoferrin binding protein A (LbpA) was successfully cloned into the vector pSB1C3.
Aim of Experiment: Amplify LbpA gene from N.meningitidis template.
Protocols Used: Click here to see our PCR protocol.
Results: Figure 1
Next Steps: Since the LbpA gene was amplified successfully, it was ready to be digested for subsequent cloning into pSB1C3.
Aim of experiment: To digest LbpA with BamHI and EcoRI and then ligate it into pSB1C3.
Protocols Used: Restriction Digests Ligations
Results: N/A
Next Steps: Ligations of LbpA + pSB1C3 were left overnight until the next day when they would be transformed into JM110 cells.
Aim of experiment: To transform the pSB1C3 + LbpA ligations into JM110 cells.
Protocols Used: Transformations
Results: N/A
Next Steps: Transformations will be checked tomorrow and if successful, overnight cultures will be set up.
Aim of experiment: To set up overnight cultures of the LbpA + pSB1C3 JM110 colonies.
Protocols Used: Overnight Cultures
Results: N/A
Next Steps: A miniprep will be performed on the overnight cultures and a pre-sequence digest test performed tomorrow.
Aim of experiment: To miniprep the LbpA + pSB1C3 JM110 overnight cultures and perform a pre-sequence restriction digest to check for the presence of the insert.
Protocols Used: Plasmid Purification (QIAprep® Spin Miniprep Kit) Restriction Digests
Results: N/A
Next Steps: Since the pre-sequencing digest worked, the miniprep will be sent for sequencing.

Aim of experiment: To amplify LbpA for subsequent cloninng into the pQE80-L vector.
Protocols Used: PCR
Results:
Aim of experiment:To restrict and ligate the LbpA gene into the pQE80-L plasmid.
Protocols Used: Restriction Digests Ligations
Results:: N/A
Next Steps: Transformations of LbpA + pQE80-L into the JM110 strain will be carried out tomorrow.
Aim of experiment: To transform the LbpA + pQE80-L ligations into the E.coli strain JM110.
Protocols Used: Transformations
Results: N/A
Next Steps: If the transformations are successful, colonies will be picked to set up overnight cultures.
Aim of experiment: To set up colony PCR from the single colony obtained from the 2:1 ligation transformation.
Protocols Used:
Results:
Next Steps: The gel indicates that the pQE80-L vector has sealed without the presence of the LbpA gene. LbpA will amplified again tomorrow.
