1. Ligation
Add 6.5uL ddH2O, 1uL T4 Ligase Buffer, 1uL pBjh1601KC Vector, 1uL Insert (Digested PCR Parts), & 0.5uL T4 DNA Ligase Incubate for 30 minutes @ Room Temp. in 500mL Eppendorf Tubes
2. Prepare Lefty E. coli Competent Cells- Yellow Test Tubes
Add 50uL ddH2O & 30uL KCM to 200uL Cells after thawing Leave on ice
3. Transformation by Heat Shock
Add 70uL cell cocktail to ligation reactions & stir Heat shock for 90sec @ 42 degrees C & Ice for 1 min. Recover w/ 100uL LB Media (Flame bottle & tips) & shake for 1 hour @ 37 degrees C Plate 70+uL mixture on Kan Plate w/ Glass Beads Green Stripes=Kan (Kanamycin)- KC vector has KnR & CmR, can use either plate Blue Stripes=Cam (Chloramphenicol) Incubate @ 37 degrees C overnight

1. EcoRI/BamHI Digestion
8uL Eluted PCR Product in 1uL NEB 2 Digestion Buffer w/ 1uL EcoRI & 1uL BamHI Incubate in 37 degrees C Thermocycler for 1 Hour
2. Run Preparative Gel
Cut out Digested Bands to Gel Purify (Lanes 2-4 of Gel B) Place gel in 600uL ADB Buffer & Melt at 55 degrees C
