  • Kunkel Mutagenesis

07/07/10

  • Stained and scanned protein gel.

BioRad Micro Column Protein Prep: Expression

  • Arctic Express 13C 24H no anti, Arctic Express 13C 24H kan, DE3* 22C 24H kan, Arctic Express 37C 24H Kan. (Both CapD and CapDCP)
    • CapD 22C kan and 37C kan grew much slower than the rest. (Takes about 3 - 4hrs vs around 1.5-2 hrs for the rest.)
      • One of the two actually decreased OD after 30 minutes.
  • Induced with IPTG after reached OD600 between .7-1.0 (CapD 22C kan and 37C reached about 1.3) and incubated at given temperatures.

07/08/10

  • Made glycerol stocks for Kunkel's. Put in -80C Freezer. To be shipped for sequencing.
  • Spin down remaining proteins(CapD Artic no Anti, CapD CP Arctic no Anti, CapD* Kan 22, CapD CP* Kan 22, CapD Kan Artic, CapD CP Kan Arctic) and place in -20C, awaiting purification.

07/09/10

Protein Purification

  • Lysis
  • Bind Protein
    • Numbers 6 and 7, CapD CP Anti and CapD CP 22, respectively, had lysate form in the supernatant that had been filtered through the TALON beads.
    • Sometimes centrifuged twice after pouring out supernatant because a significant amount had not filtered through TALON beads
  • Wash Protein
    • Sometimes centrifuged twice after pouring out supernatant because a significant amount had not filtered through TALON beads
  • Elution

(Note: Desired proteins have excess histidine chain that binds to TALON beads. Imidazole has higher affinity for TALON beads, so higher imidazole concentration pushes desired protein off, allowing it to fall through filter. This is why higher and higher concentrations of imidazole are used. Cleans off undesired proteins first all the way up to, hopefully, only the desired protein.)

Electrophoresis

  • Ran two gels. #1 has ladder in well 1. #2 has ladder in well 2. 3 wells per condition being Lysate, Supernatant, Purified, in that order. SDS 6uL+6uL of substance for mix. 10uL per well.

  • Use 1uL of each protein sample with 9uL Coomassie dye and measure with program.

Overnight Glycerol Stocks

  • CapD/CapD CP TB (LB?) Kan solutions with a dab of glycerol from -80C (just scrape glycerol with pipette tip and drop into TB Kan solution).
  • Incubate in 37C shaker overnight.
