Zn(2+) and Co(2+) ions are known to promote human growth hormone reversible dimerization. In these studies, dimerization was also shown to be initiated by nine other metal ions: Cd(2+), Hg(2+), Cu(2+), Ag+, Au(3+), Au+, Pd(2+), Ni(2+), and Pt(4+). In some
TAHT (1,3,5-triacryloylhexahydro-s-triazine), a reactive chemical coupling agent, was highly toxic following a single peroral dose of an aqueous suspension (10% w/v) to Wistar rats, or following application of TAHT in dichloromethane (DCM) solution (10% w/v) to covered skin of New
Six difunctional and trifunctional derivatives of acrylamide were synthesized and investigated as potential protein lysine residue cross-linking agents. 1,3,5-Triacryloyl-hexahydro-s-triazine (TAT) was considered the best. The rate constants for the reactions of TAT with model nucleophiles in water solution at 25
The properties of polyacrylamide hydrogels synthesized with a novel hexafunctional (three double bonds) cross-linker, hexahydro-1,3,5-triacryloyl-s-triazine (1a), was evaluated and compared to the currently used tetrafunctional (two double bonds) cross-linker N,N-methylenebisacrylamide (Bis). A variety of characterization techniques that require very little
The kinetics of the nucleophilic addition reactions of divinyl sulfone to amino groups of glycine and model proteins was studied in aqueous solution at 30 degrees C. The rate constants for glycine, bovine serum albumin, and alpha 1-casein were (4.84
