Several of us have benefited from John Crea's and 3M's generosity
in providing research samples of several lots of polyethylene for our
evaluation in MALDI mass spectrometry applications. That access to
appropriate sizes of materials not commercially available has aided
us in our work: Int. J. Mass Spectrom. 169-170, pp. 273-290 (1997)
"Diffusive Transfer to Membranes as an Effective Interface between
Gel Electrophoresis and Mass Spectrometry". Since
Blackledge and Alexander's 1995 paper a number of us have
inquired about availability of these membranes but there has
always been the problem of commercial viability.
I suppose that in a strict sense, the recent announcement from
3M probably would appear to many to be "marketing", but I support
this announcement because I interpret it to be a sincere effort to
determine whether a single lot of an experimental material is worth
producing; if there is insufficient interest the material will not be
available.

Pardon me, but I thought this group was for the exchange of ideas and a
resource of information, not a marketing medium. I do not like it!
