Purification of histone core octamers and 2.15 A X-ray analysis of crystals in KCl/phosphate.

Acta Crystallogr. D Biol. Crystallogr. 55(Pt 5) , 1048-51, (1999)

Intact histone octamers, produced by a new method quickly and in bulk, were crystallized in KCl/phosphate, and the X-ray data were analysed to 2.15 A, confirming a P65 space group. This environment pr...

Indirect atomic absorption determination of atropine, diphenhydramine, tolazoline, and levamisole based on formation of ion-associates with potassium tetraiodometrcurate.

J. Pharm. Biomed. Anal. 25(1) , 3-7, (2001)

Ion-associate complexes of atropine sulphate (I), diphenhydramine HCl (II), tolazoline HCl (III) and levamisole HCl (IV) with potassium tetraiodomercurate were precipitated and their solubilities were...

A simple diffuse reflectance Fourier transform infrared spectroscopic determination of sulfur dioxide in ambient air using potassium tetrachloromercurate as the absorbing reagent.

J. AOAC Int. 90(4) , 1180-90, (2007)

This paper presents development of a simple, rapid, and precise analytical method for determination of sulfur dioxide in ambient air by a gas to solid-phase conversion method. Sulfur dioxide is determ...
