Eosin B is used to estimate proteins above 1 microg/ml concentration [Waheed AA, Gupta, PD. Anal. Biochem. 1996:233:249-256; Waheed AA, Gupta PD. J. Biochem. Biophys. Meth. 1996;33:187-196]. In the present report we describe a method for estimating submicrogram quantities of

4',5'-Dibromo-2',7'-dinitrofluorescein, a red dye commonly referred to as eosin B, inhibits Toxoplasma gondii in both enzymatic and cell culture studies with a 50% inhibitory concentration (IC(50)) of 180 microM. As a non-active-site inhibitor of the bifunctional T. gondii dihydrofolate reductase-thymidylate
A A Waheed et al.
Journal of biochemical and biophysical methods, 33(3), 187-196 (1996-12-30)
We describe a detailed procedure for estimating a wide range of proteins by the eosin B dye method. At acidic pH, eosin B binds to proteins and absorption of the protein-dye complex at 536-544 nm is proportional to the concentration

We examined the potential contribution of a voltage-gated proton conductance (gH+) to acid extrusion from cultured postnatal rat hippocampal neurons. In neurons loaded with Ca2+- and/or pH-sensitive fluorophores, transient exposures to 25-139.5 mM external K+ (K+o) or 20 microM veratridine

We synthesized mefenamic acid (MA) derived gold nanoparticles (MA-AuNps) in aqueous solution (MA-Au sol). Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) of the sol at 1, 5, 15 and 60 min showed changes in size and shape of
