On the basis of the physico-chemical principles underlying silver-staining of proteins, which are recalled in this paper, several methods of silver-staining of proteins after SDS electrophoresis in polyacrylamide gels or isoelectric focusing were tested. The most valuable protocols are presented in this report, including standard methods for unsupported gels and new methods devised for thin (0....

The ultrastructural distribution of proteins B23 and nucleoiin in the nucleolus of mouse embryos from the zygote to the early blastocyst has been analyzed by means of specific antibodies and immunocytochemistry using colloidal gold complexes as markers. In parallel, silver staining of nucleoli was carried out on ultrathin sections. Our results show that the compact prenucleolar bodies at 1and 2...

the invention of 2-D poly-acrylamide gel electrophoresis (2-D PAGE) (1,2) marked the beginning of what has now become a classic and dominant proteomics technology. Over the years, many refinements in the underlying technology have been made (reviewed in Reference 3), but some of the most important improvements and advancements have focused on increasing the sensitivity and visualization of the ...

This study investigates the physical basis of color effects in the detection of proteins in polyacrylamide gels by silver staining. Specifically, the hypothesis that different colors may correlate with the development of silver grains of characteristic sizes was investigated by electron microscopy. Protein bands that stained brown, yellow, and blue were excised from stained gels and prepared fo...

We subjected cerebrospinal fluid (CSF) from 20 patients with multiple sclerosis and 20 patients with other neurological diseases to agarose gel ( Panagel ) electrophoresis followed by staining with silver. Ten microliters of unconcentrated CSF from multiple sclerosis patients containing 0.4 to 0.8 microgram of immunoglobulin G was found to be optimum for detection of oligoclonal IgG bands, so i...

Objective: To explore a fast and sensitive method for screening T cell receptor (TCR) biases through comparison of silver staining for polyacrylamide gel electrophoresis and ethidium bromide staining for agarose gel electrophoresis. Methods: The lymphocytes were isolated from peripheral blood which collected from ten patients with T1DM; the total RNA was extracted followed by transformed to cDN...
