6/14/18
-Got familiar with lab
-Made LB and normal YPAUD liquid media
-Labelled liquid media and left on bench shelf
-Make chloramphenicol plates
-250mg chloramphenicol; marked by CAM

6/15/18
-Made Arg- YPAUD liquid media
(-Used CSM -Arg, -Ura; added uracil in a 1:1 ratio with CSM (1.7g of CSM -Arg -Ura, 1.7g of uracil)
-Marked by 3 blue stripes
-Made Arg- YPAUD plates
    -Used CSM -Arg, -Ura; added uracil in a 1:1 ratio with CSM
    -Marked by three blue stripes
-PCR amplify arg-ars sequence
    -Total volume: 50µL
        -35µL water
        -10µL 5X phusion buffer
        -1µL dNTPs
        -2.5µL 10µM primer stock (forward and reverse arg-ars primers)
        -1µL pOW1 (17.6 ng/µL) DNA stock (0.8µL DNA, 4.2µL H2O)
        -0.5µL phusion
        -Stored in refrigerator next to PCR machine (labeled iGEM arg-ars PCR)

6/18/18
-Gel electrophoresis of arg-ars sequence (PCR amplified on 6/15/18)
    -Check if PCR was successful
    -Agarose gel:
        -40 mL 1X SB buffer, 0.32g agarose
        -Mixed and microwaved for 35 seconds
        -Added 2µL EtBr to agarose gel in flask
    -Agarose gel opaque and gray when fully polymerized
    -Sat in chamber, completely covered in buffer, until ready to run the gel
-Gel was unsuccessful, neither the ladder band nor the PCR product band could be observed
    -Suspected problem: samples not loaded into wells properly
        -Large smear of DNA across wells observed
-PCR amplified arg-ars sequence with 1 min per Kb (5 min since Arg-ars sequence is 4.86 Kb)
    -Labeled in blue marker
