Collagen and related research, 7(6), 399-407 (1987-12-01)
The intracellular degradation of interstitial collagen is accomplished by two neutral metalloproteases, collagenase and gelatinase. Both enzymes are inhibited by metal chelating agents, by certain sulfhydryl reagents, and by similar protein inhibitors. Here, we demonstrate that the dye eriochrome black

Proteomics, 6(8), 2334-2337 (2006-02-24)
A quick, sensitive, and MALDI-TOF MS compatible silver staining method, namely Eriochrome black T (EBT)-silver method, is described. The method can detect 0.05-0.2 ng protein within 60 min in SDS-PAGE gels. EBT dye was used as a silver ion sensitizer
