This product is for research use only. Do not administer it to human.This silver staining kit is produced for mass spectrometric sequencing of protein separated by polyacrylamide gel electrophoresis, based on the method described by Shevchenko, et al. By silver staining, protein is rarely modified chemically due to omitting treatment of glutaraldehyde and is detected at several nanograms level on the elecrophoretic gel.[Features]Detectable limit of protein: 1 ngideal for MS analysis because rarely modified protein is obtained due to omitting glutaraldehyde treatment.
