I didn’t say anything regarding that.

Just to elaborate my point: The process of protein cristallization is not understood at a level that allows the design of general and reproducible protocols. This inherent obscurity means that every new protein needs to undergo an ad hoc, heuristic, iterative process to obtain high quality crystals. This is an early methodological hurdle, at a stage where other routine procedures in biochemistry or molecular biology are usually successful.

I said that. We had a saying in grad school, "the very best protein structures are crystallized from postdoc tears".

  • As a current postdoc (genetics) I think postdoc tears are the fuel that academia runs on - as well as those of our significant others and kids.

I know you didn't - this was one of the claims of ramraj I was responding to.

I don't disagree, though I would suggest that there's just as much grunt work, frustration, and hand wringing in other fields of molecular biology at the graduate level and above. Even if other fields have reproducible protocols established, that's not what gets papers published. With the possible exception of clinical samples, more often than not we have no clue if the analyses we're doing will yield anything, and the high risk zone is where all grad students live.
