      100ml

      Tris-HCl(pH 7.5)

      0.22 filtered D.W

       

       

      47ml

      Glycerol treatment 주위 (정확한 넣어줄 .)

       

      100ml solution total 1g PK 녹여준다.

      10mg/ml stock 만들어짐.

       

      II. TES 만들기

        1cm정도로 자른 꼬리에 TES 500+ PK20(=100~200/1cm tail)

            처리한 후 58OC에서 O/N

      .Water bath 58OC로 미리 setting 해놓는다.

      PK60OC 이상으로 처리할 경우,PK가 파괴되므로 절대 넘지 않도록 주의.

      PK는 녹여서 잘 inverting해준 후에 사용한다.
