digestion check of CinR+HSL+D-term,pCinRHSL and pOmpC (vectors)

lane A: 1kb ladder lane B: CinR+HSL+D-term x 2 lane C: 1kb ladder lane D: pCinRHSL x 2 lane E: pOmpC x 2

• after gel separation, their O.D. was checked. However, it is too low

Re-check the concentration of inserts and vectors

lane A: 1kb ladder lane B: pCinRHSL lane C: pOmpC lane D: CinR+HSL+D-term lane E: 100bp ladder lane F: TATA_INSA lane G: TATB_INSB lane H: OmpRBS

Owing to concentrations of vectors are too low and A260/A280 ratios are not correct (maybe too much ions) thus, we checked the vectors with inserts by PCR to decide how to ligate them

ligation setup

• criteria
  • make vector have 100 ng in sample (total volume 20 uL)
  • maximize the insert volume

ligation I: pCinRHSL (vector) + OmpRBS (insert)	ligation II: pOmpC (vector) + TATA_INSA (insert)	ligation III: CinR+HSL+D-term (vector) + TATB_INSB (insert)
pCinRHSL (vector) 3 uL OmpRBS (insert) 14 uL 10X buffer 2 uL T4 ligase 1 uL	pOmpC (vector) 4.5 uL TATA_INSA (insert) 12.5 uL 10X buffer 2 uL T4 ligase 1 uL	CinR+HSL+D-term (vector) 3 uL TATB_INSB (insert) 14 uL 10X buffer 2 uL T4 ligase 1 uL
