Towards novel C–N materials [PDF]
, 2004 Two modifications of the novel guanidinium dicyanamide have been obtained by means of ion-exchange reaction in aqueous or methanolic solution. The hygroscopic compounds were characterized by solution state NMR, mass spectrometry and vibrational ...

Accumulation, localization, and compartmentation of transforming growth factor beta during endochondral bone development. [PDF]
, 1988 Endochondral bone formation was induced in postnatal rats by implantation of demineralized rat bone matrix. Corresponding control tissue was generated by implanting inactive extracted bone matrix, which did not induce bone formation.

A novel, resistance-linked ovine PrP variant and its equivalent mouse variant modulate the in vitro cell-free conversion of rPrP to PrPres [PDF]
, 2006 Prion diseases are associated with the conversion of the normal cellular prion protein, PrPc, to the abnormal, disease-associated form, PrPSc. This conversion can be mimicked in vitro by using a cell-free conversion assay. It has recently been shown that

Biotechnology Progress, EarlyView.Abstract The production of disulfide‐containing recombinant proteins often requires refolding of inclusion bodies before purification. A pre‐refolding purification step is crucial for effective refolding because impurities in the inclusion bodies interfere with refolding and subsequent purification.

Growth inhibition of neurospora by canavanine, and its reversal [PDF]
, 1948 Canavanine, an amino acid from jack beans, was discovered by Kitagawa and coworkers in 1929 (1, 2). The substance is not combined in the proteins of the seed, but occurs in the free state, and makes up 2.5 per cent of the dry weight of jack beans (3). In
