Concentrations of fluoride in salt range from 90 to 350 mg/kg, with studies suggesting an optimal concentration of around 250 mg/kg.

"Our lab would then select active ingredients in optimal concentrations just for her," says Souza.

Transfected 293 cells expressed nine times as much TTP as the untransfected cells at the optimal working concentration of antibody.

The swimming capacity increase with the ionic strength and 100mM is the optimal concentration for the rotation of flagella.

It was hypothesized that interactions between neurotrophic factors could alter the optimal concentrations of each factor.

A series of experiments was performed to detect the optimal concentration of butyrate in the culture system.

As long as the Earth's magnetic field has a significant downward slant, the orientation along field lines aids the search for the optimal concentration.

The Bromfenac Comparative trial was done to determine the optimal concentration for a once daily formulation.

When used at their optimal respective concentrations, the two combined have been shown to reduce cell death more than when alone.

The enzyme is also capable of oxidizing thiocyanate (SCN-) and uses it as a co-substrate, with optimal concentrations occurring at about normal plasma levels.
