Two forms of des - (b chain C-terminal pentapeptide) insulin crystals are grown for preliminary X-ray diffraction observations. Crystallographic data for these crystals have been obtained.

And trying to improve on something that's already at the top of the food chain is a a waste of time and b likely to just make it worse for the wear.

Clonal immunoglobulin heavy chain gene rearrangement can be used as a effective diagnostic molecular marker for B-NHL.
