I wonder why some biologists use PIPES pH 8.0 in lysis buffers in Protocols?
whereas the buffering range of it is 6.1-7.5 pH.

You can find those protocols even in high rank universities.

buffers are routinely misused when the procedure works anyway (e.g. tris used for stacking gel buffers in sds-page).

however, sometimes buffers are blended to extend buffering range and/or to buffer a pH that would otherwise have to be reached with a incompatible buffer salt.

are there other buffer salts in your lysis media?
