PCR amplification of CGRP II mRNA. Variable expression in tumoral and non-tumoral human thyroid.

abstract：:Under destabilising conditions both heat and cold denaturation of yeast phosphoglycerate kinase (PGK) can be observed. According to previous interpretation of experimental data and theoretical calculations, the C-terminal domain should be more stable than the N-terminal domain at all temperatures. We report on thermal...
