Thanks a lot |

y****6 发帖数: 196 | 4 Thanks for sinister and kaka1000's reply. I labeled the antibody with
fluorescent dyes and quenchers, and I want to digest the antibody to small
fragments to break the FRET between dyes and quenchers. It would be best if
I can digest the antibody into the smallest fragments. Papain may not be the
best choice as it only cut antibody into three pieces. Maybe I can use some
kind of protease mixture? Any suggestion is welcome. |

therefore you have to try it out yourself by using different available
proteases or even a mixture if the proteases do not affect each other. |
