35S-GFP Composite Results - With careful inspection of my gels, I believed Lane 3 was a good candidate. I was looking for 2 bands, the composite at about 1.8kb and the pSB1C3 backbone at 2kb. Although, the image is not clean, I believed I saw a second band emerging in between the molecular markers which were 2kb and 1.6kb, making that emerging band at 1.8kb. Sequencing would prove me right

Rd29A in TOPO Vector.jpg

  • The "rd29A in Topo Vector" gel analysis was successful for it showed the rd29A bands at ~836 bp and the Topo bands at ~3,519 bp. (Digested/Cut samples with EcoR1 and Pst 1 = labeled C5, C6, C7, & C8).
    • Digested rd29A (Topo Vector) and RFP (pSB1C3)with EcoR1 and Pst 1.
    • Ethanol Precipitation of the rd29A (Topo Vector) and RFP (pSB1C3).

  • Elaine
    • 30 Cell cultures of rd29A (pSB1C3)
    • Minipreped 30 cell cultures expected to have the rd29A (pSB1C3). Concentrations were too low and therefore only 4 colonies were digested.
    • Digested 4 colonies (labeled as seen on the gel below: #1, #3, #13, #15) suspected to have the rd29A in the iGEM(pSB1C3) Vector
    • These 4 colonies were ran on a 1.2% Agarose gel for analysis - "rd29A in iGEM (pSB1C3) Vector"

Rd29A in pSB1C3 - Epic Failure.jpg

  • The "rd29A in pSB1C3 iGEM Vector" gel analysis was NOT successful for the expected bands of the rd29A at ~836bp didn't show up on the digested (cut with EcoR1 & Pst 1) labeled C1, C3, C13, & C15.
    • 45 Colony PCR of rd29A (pSB1C3)
    • Ran 45 Colony PCR of rd29A (pSB1C3) on 1.2% Agarose gels

  • The "Colony PCR # 21 of rd29A in pSB1C3 iGEM Vector" gel analysis was successful for 1 (colony PCR #21) out of 45 colonies showed an rd29A band at ~836bp.(Band is shown in the lane labeled #21).

  • Matthew
    • Submitted 35S-GFP to iGEM
  • Richard and Nick

Week of October 24-30:


  • Elaine
    • Added rd29A (pSB1C3) into the registry
    • Submitted rd29A (pSB1C3) through the mail.
