Hi,
Someone may have already mentioned this, but catalase is another great
biological TEM standard. It's commercially available, can be
recrystallized into TEM-thin platelets and is a great teaching tool for
electron diffraction, low dose, cryoTEM, etc.

These standards would be used show new TEM users what sort of data they can expect with correctly prepared and handled samples. I suppose the only requirements for this standard would be MW >250kd, that it stains well with Uranyl Acetate or Uranyl Formate and that it be fairly homogeneous.

If necessary we will purify our own but I thought maybe someone on this listserv may have more information on how to obtain such a standard. Thank you for your time and help.
