Abstract:
Objective To apply two-dimensional (2-D) gel electrophoresis to resolve specially expressed proteins related to retinitis pigmentosa (RP) in the retina of rds mice.Methods Proteins, prepared from the retinas of rds mice and normal C3B mice at different ages, were separated by using two-dimensional electrophoresis and then analyzed by 2-DE imaging analyzer.Results 2-D gel electrophoresis was established for the retinal proteome analysis. Retinal neuronal tissue was lysed by using chemical lysis solution and ultrasonic. Using carrier ampholyte to set up pH gradient as first dimension and casting vertical 12% SDS-acylamide-bis slab as second dimension, the major retinal proteins showed maps of proteome on 2-D gels clearly. Retinal proteome of rds and C3B mice at 37d has different expressive patterns. Some proteins only expressed in the retina of rds mice while another only in the retina of C3B mice and others had different level between the two kinds of mice.Conclusion 2-D gel electrophoresis is effective to separate specially expressed retinal proteins. The expressed proteins in the rds retina are different in quality and quantity from that in the normal C3B mice.
