Shape Imprinting Due to Variable Disulfide Bonds in Polyacrylamide Gels

Polyacrylamide gels with electrostatic functional groups for the molecular imprinting of lysozyme

The system of polyacrylamide incorporated with methacrylic acid and 2-(dimethylamino)ethyl methacrylate was studied for the possibility of imprinting of lysozyme. The results show that approximately 27% (w/w) of the lysozyme template was not able to be extracted from the molecularly imprinted acrylamide polymers. The amount of the lysozyme template able to be extracted was increased by the addi...

Demonstration of rhodanese activity in polyacrylamide gels.

Rhodanese activity from crude extracts of Thiobacillus sp. strain IV-85 was demonstrated in polyacrylamide gels after incubation in the reaction mixture by staining with dichloroindophenol in the presence of methylphenazonium methosulfate. The sensitivity of the staining system was found to be 8 x 10 moles of sulfite.

Steps toward peptide polymerization in polyacrylamide gels

Formation and Structure of Polyacrylamide Gels

Acrylamide and N,N-methylenebis(acry1amide) (AAm-Bis) copolymerization has been investigated in water at a monomer concentration of 1.8 w/v %. Conversion of monomer and pendant vinyl groups was measured as a function of the reaction time up to the onset of macrogelation. Experimental results indicate that 80% of pendant vinyl groups are consumed by cyclization reactions. When the monomer concen...
