In vitro inhibition of hyaluronidase by sodium copper chlorophyllin complex and chlorophyllin analogs
TLDR
The concept of using hyaluronidase inhibitory activity of sodium copper chlorophyllin complex to increase the hyaluronic acid level of the dermal extracellular matrix for the improvement of the appearance of aging facial skin is supported. Expand
Kinetic scheme for Ca2+-arsenazo III interactions.
TLDR
The relatively slow rate-limiting step sets a limit for the use of arsenazo III to study the kinetics of Ca2+ processes in cell biology. Expand
Binding of DTNB to band 3 in the human red cell membrane.
TLDR
A detailed investigation of DTNB binding to red cell membranes that had been treated with the sulfhydryl reagent N-ethylmaleimide (NEM), and results support the view that band 3 is a principal constituent of the red cell aqueous channel, through which urea and ethylene glycol also enter the cell.

Spectrophotometric determination of reaction stoichiometry and equilibrium constants of metallochromic indicators. II. The Ca2+-arsenazo III complexes.
TLDR
The analytical method described in the preceding article was applied to spectrophotometric Ca2+-titrations of the metallochromic indicator arsenazo III (Ar) and it was determined that Ar forms 1:1,1:2 and 2 : 1 complexes with calcium. Expand
Spectrophotometric determination of reaction stoichiometry and equilibrium constants of metallochromic indicators. III. Antipyrylazo III complexing with Ca2+ and acetylcholine receptor protein.
TLDR
This is the first reported indication that antipyrylazo III binds to biological material and questions the usefulness of this dye as a Ca indicator in biological systems. Expand
Spectrophotometric determination of reaction stoichiometry and equilibrium constants of metallochromic indicators. I. General calculational method.
A calculational method is developed for spectrophotometric determination of stoichiometrics and individual equilibrium constants in the complexing of metal ions with metallochromic indicators.Expand
Arsenazo I and tetramethylmurexide as optical calcium indicators.
Calcium-binding stoichiometry, dissociation equilibrium constants at zero ionic strength @Lo), and molar extinction difference coefficients (At,) at the wavelength )r of the metallochromic indicatorsExpand

TLDR
Dependence of the relaxation rate of arsenazo III on dye and Ca2+ concentrations indicates the presence of both CaAr and CaAr2 complexes, with the Ca Ar2 form being responsible for the slow, 10-20 ms relaxation of this dye. Expand
