0. DNA 종류
-> (random) 8 mer: 5’ biotin – GCTACACG – 3’ // CG 비율 50% 보다 높음
-> (random) 12 mer: 5’ biotin – AGCTACACGATA – 3’ // CG 비율 50% 보다 낮음
-> 12 mer: d(A)_12
1. TIRFM
1) 조건
->immobilization 방법:
->probe 농도:
->target 농도:
->imaging buffer & 온도:
->time resolution:
->time lapse
+ w/o probe imaging:
2) time-intensity plot
->최대 intensity:
->oligo 종류 따라:
3) association time histogram
->(어떻게 측정?: threshold?)
->k’_off & association time count 관계
->oligo에 따른 histogram 차이(area 나눈 기준은?)
=>8 mer:
=>12 mer:
=>d(A)_12:
-> (quenching 고려한) k_off & lapse time 관계식:
=> quenching 기여 제거:
4) 분석
->multi-slope 이유:
=>12 mer: (fast)
(slow)
=>d(A)_12: (slow)
(middle)
2. QCM
1) 조건
2) TIRFM과 비교
3. dA_12, d(ATG)_4 분석 (1? 2?)
