SDS와 NaOH를 이용해서 cell을 깨고 chromosomal DNA와 protein등을 denaturation 시킴
High pH : DNA가 base pairing을 못함
Plasmid의 경우 작고 CCC form 이기 때문에 완전히 나눠지지 못함
pH가 정상으로 돌아오면, chromosomal DNA는 Protein등와 함께 침전되고 Plasmid는 상층액에 속함

Dialysis
What is dialysis?
Dialysis is a membrane process where solutes (MW~<100 Da) diffuse from one side of the membrane (feed side) to the other (dialysate or permeate side) according to their concentration gradient. First application in the 70’s.
General Principles
Separation between solutes is obtained as a result of differences in diffusion rates.
These are arising from differe
of time, most of the biogenic methane has been generated. Also at this time nearly two thirds of the moisture has been expelled and the coal has reached a rank of subbituminous (Rightmire, 1984).
After the coal’s temperature has exceeded 122 degrees Fahrenheit due to the geothermal gradient and excessive burial, thermogenic processes begin to generate additional carbon dioxide, nitrogen, metha

The building’s sophisticated, minimalist redesign, undertaken by the Greek architectural firm Point Supreme, uses a gray-scale gradient color scheme that darkens as the site progresses from the airy, white gallery space to the slate-colored cafe-library to the large, char
