TesA module's lablog

  • JulyOpen or Close

    Week 3 (13/7~19/7)

    - Primer design for leaderless tesA for Fit-coli (‘tesA) & New biobrick (‘tesA BB)

    Week 4 (20/7~26/7)

    - PCR of ‘tesA and ‘tesA BB

    - PCR purification of ‘tesA and ‘tesA BB

    - Prepare LB agar plates(‘tesA BB)

    Week 5 (27/7~31/7)

    - Digestion of ‘tesA BB and pSB1C3 plasmid with EcoRI & PstI restriction enzymes

    - PCR purification for digested ‘tesA BB

    - Sub-cloning of ‘tesA BB into pSB1C3 plasmid

    - Transformation of ‘tesA BB into W3110 E.coli

    - Pick colonies of the transformed E. coli with ‘tesA BB

  • Early AugustOpen or Close

    Week 1 (1/8~2/8)

    - Cell lysis of picked E. coli with ‘tesA BB

    - Colonies PCR of ‘tesA BB by using VF2 & VR primer

    - Send the ‘tesA BB plasmid for sequencing

    Week 2 (3/8~9/8)

    - 2nd PCR of ‘tesA
    ∵ The first PCR product of ‘tesA was degraded over a long period of storage time

    - PCR purification of ‘tesA PCR product

    - 1st Digestion of ‘tesA by using XbaI & PstI restriction enzyme
    -> After running gel, no fragment showed in pilot ( other plasmid with the Xbal & Pstl respectively) , could not determine whether the digestion was success or not

    - 2nd digestion of ‘tesA by using XbaI & PstI restriction enzyme with adding one more control pilot that is only plasmid with no enzyme
    -> Still no fragment presented in pilot, we wonder whether the pilot plasmid or the restriction enzyme had problem

    - 3rd digestion of lac promoter in pSB1C3 plasmid & pbad promoter in pSB1C3 plasmid by using EcoRI, XbaI, SpeI & PstI restriction enzyme
    -> All of the restriction enzyme worked normally, but the pbad promoter in pSB1C3 plasmid was degraded

    - 4th digestion of ‘tesA by using XbaI & PstI restriction enzyme

    - Sub-cloning of‘tesA into rbs in pSB1C3 plasmid (Part: BBa_B0030)

  • Late AugustOpen or Close

    Week 3 (10/8~16/8)

    - 1st Transformation of ‘tesA with rbs (BBa_B0030) into W3110 E.coli

    - Pick colonies of the transformed E. coli with ‘tesA & rbs (BBa_B0030)

    - Send the‘tesA with rbs (BBa_B0030) plasmid for sequencing
    ∵ The sequencing result showed the coding error of the rbs
    -> Used BBa_B0034 rbs in pSB1C3 plasmid to replace BBa_B0030 rbs for 2nd cloning

    Week 4 (17/8~23/8)

    - 3rd PCR of tesA’
    ∵ The 2nd PCR product of ‘tesA was used up

    - PCR purification of ‘tesA PCR product

    - 5th digestion of ‘tesA by using XbaI and PstI restriction enzyme

    - Sub-cloning of ‘tesA into rbs in pSB1A2 plasmid (Part: pSB1A2- BBa_B0034)

    - Miniprep of pbad promoter (Part: pSB1C3-BBa_I13453)

    - 2nd tramsformation of ‘tesA with rbs (BBa_B0034) into W3110 E.coli

    - 1st digestion of pbad promoter (BBa_I13453) by using SpeI & PstI restriction enzyme

    Week 5 (24/8~30/8)

    - Pick colonies of the transformed E. coli with ‘tesA & rbs (BBa_B0034)

    - Cell lysis of the picked E. coli with ‘tesA & rbs (BBa_B0034)

    - Colonies PCR of ‘tesA & rbs (BBa_B0034) by using VF2 & VR primer

    - Send the‘tesA with rbs (BBA-B0034) plasmid for sequencing

    - Miniprep of ‘tesA with rbs (BBa_B0034)

    - 1st digestion of ‘tesA with rbs (BBa_B0034) by using XbaI & PstI restriction enzyme

    - Gel purification of digested ‘tesA with rbs (BBa_B0034)

    - PCR purification of pbad promoter (BBa_I13453) digested in week 4
