Title: A mechanically strong matrix for protein electrophoresis with enhanced silver staining properties. Author: Patton WF, Lopez MF, Barry P, Skea WM. Journal: Biotechniques; 1992 Apr; 12(4):580-5. PubMed ID: 1503760. Abstract: Duracryl is a mechanically strong and elastic acrylamide-based matrix, useful for a wide variety of electrophoretic applications. The matrix is stable as a refrigerated solution for one year. Upon addition of appropriate catalysts, Duracryl forms a polymer-reinforced polyacrylamide gel matrix suitable for electrophoresis. The polymer-reinforced gel is superior to conventional polyacrylamide gels in terms of mechanical strength, elasticity and protein silver staining properties. Protein detection sensitivity by silver staining, as well as the linear response of silver deposition versus protein load, is equivalent to standard acrylamide/N,N'-methylene bisacrylamide gels. Additionally, the silver staining properties of the Duracryl matrix result in proteins appearing as monochromatic shades of grey instead of red, brown and yellow, as is the case of conventional polyacrylamide matrices. Monochromatic shades of grey are more suitable for image analysis and densitometry. The matrix is compatible with standard electroblotting and protein N-terminal sequencing procedures. Low acrylic acid content and conductivity allow incorporation of the matrix into isoelectric focusing gels. The matrix was found not to alter polypeptide migration relative to the standard acrylamide/N,N'-methylene bisacrylamide matrix.[Abstract] [Full Text] [Related] [New Search]
