Preparation and comparative solubility of poly-L-tyrosyl lysozyme and poly-O-methyl-L-tyrosyl lysozyme

Creator:

Venier, Lynn Corrine

Abstract:

In order to examine some possible tyrosyl interactions, poly-tyrosyl lysozyme and poly-O-methyltyrosyl lysozyme were prepared and their solubilities were compared. Both derivatives exhibited similar pH dependent solubilities, showing a minimum solubility at about pH 8. Their solubilities varied with temperature, having a positive enthalpy of solution. The effect of a...

Fabrication and application of polymer based microfluidic devices

Creator:

Koesdjojo, Myra T.

Abstract:

The concept of reducing laboratory operations in scale such that they fit on a microfluidic chip has been met with great enthusiasm. Lab-on-a-chip devices promise to be cost effective to operate due to reduced reagent consumption, have the potential to offer shorter analysis times due to their short path lengths,...

Some biochemical studies of phenylmercuric acetate and mercuric acetate toxicity in rats

Creator:

Ellis, Robert William

Abstract:

Biochemical studies of phenylmercuric acetate (PMA) and mercuric acetate toxicity in rats carried out during this investigation were (1) the metabolism of ²⁰³Hg(Ac)₂ and ²⁰³Hg-PMA within kidney and liver tissues following oral ingestion, (2) the effect on some soluble enzyme activities and determinations of ²⁰³Hg binding in the enzyme fractions,...
