Namon Hirun et al.
International journal of pharmaceutics, 388(1-2), 196-201 (2010-01-16)
A novel gel system was obtained by mixing aqueous solutions of tamarind seed xyloglucan (TSX) and Eriochrome Black T (EBT), an antiangiogenic compound. The shear-viscosity flow curves revealed that all the studies mixtures displayed a shear thinning behavior. Viscosity increased

Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy, 73(5), 794-798 (2009-05-05)
A new, rapid, sensitive, non-extraction batch, and flow injection spectrophotometric method for the determination of cationic surfactants (CSs) such as cetyltrimethyl ammonium bromide (CTAB), tetra-n-butyl ammonium chloride (TBAC) and cetylpyridinium chloride (CPC) is proposed. The method is based on the

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

Guang pu xue yu guang pu fen xi = Guang pu, 25(9), 1493-1495 (2005-12-29)
A kinetic spectrophotometric method for the determination of trace phenanthroline was proposed. The method is based on the inhibition of phenanthroline to the discoloring reaction of EBT oxidized by hydrogen peroxide in the dilute acetic acid solution. At the same
