Dose-related effects of methapyrilene (MP) on protein modification and expression were examined using two-dimensional gel electrophoresis (2-D PAGE) coupled with computer analysis. Methapyrilene was administered ad libitum at doses of 0, 62.5, 125, 250 and 1000 p.p.m. to male F-344 rats for 12 weeks beginning at 8 weeks of age. Following treatment, livers were removed and frozen for 2-D PAGE an...
In this work, we present a home-made two-dimensional (2-D) CCD imaging system for the monochromatic densitometry of plane gels and its application to the imaging and densitometry of chlorophyll (Chl)-containing proteins separated by non-denaturing polyacrylamide gel electrophoresis. The monochromatic imaging of separated green bands at the wavelengths corresponding to their absorption band incr...
We developed a method for the detection of phosphatase activity using fluorogenic substrates after polyacrylamide gel electrophoresis. When phosphatases such as Ca2+/calmodulin-dependent protein kinase phosphatase (CaMKP), protein phosphatase 2C (PP2C), protein phosphatase 5 (PP5), and alkaline phosphatase were resolved by polyacrylamide gel electrophoresis in the absence of SDS and the gel was...
This protocol describes the detection of small RNAs (~10-200 nucleotides) by blot hybridization. The RNA samples, denatured in formamide, are separated by denaturing polyacrylamide gel electrophoresis. Because high-percentage polyacrylamide gels are required to separate RNAs in this size range, it is necessary to perform electrophoretic transfer to positively charged nylon membranes. After tran...
A new method for aligning families of two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) images arising in proteomics studies is presented. Forward piecewise bilinear transformations are used to determine an ideal gel and to obtain an initial alignment of the family of gels to this ideal gel. Both the ideal landmarks and the coefficients defining the transformations are obtained by so...
