Abstract: There is provided a method for quantifying a subject substance, of which typical examples are amino acids. The method of the present invention comprises the following steps: the step of allowing an enzyme that can generate pyrophosphate by using adenosine triphosphate (ATP) as a substrate with converting the subject substance to act on the subject substance to generate pyrophosphate; the step of allowing pyruvate pyrophosphate dikinase (PPDK) to act on the generated pyrophosphate in the presence of adenosine monophosphate (AMP) and phosphoenolpyruvate (PEP) to generate ATP, phosphoric acid, and pyruvate; and the step of quantifying the generated pyruvate, and amount of the subject substance is determined on the basis of the obtained amount of pyruvate. According to the present invention, an amino acid in a biological sample containing a lot of various kinds of contaminants such as inorganic phosphoric acid and urea can be conveniently and quickly quantified without being influenced by the contaminants.
Abstract: A method of producing protein nanoparticles from waste chicken feathers by enzymatic hydrolysis followed by ultrasonic treatment is disclosed. The process includes pretreatment of the chicken feathers. Then feather fibers are hydrolyzed enzymatically. The effects of enzyme concentration, hydrolysis time, and substrate concentration on particle mean size are analyzed to optimize the best condition in order to attain the smallest particles by a Box-Behnken Design. A minimum particle size is obtained by using 5 g/l feather and 3.6% enzyme with a hydrolysis time of 243 h. The hydrolyzed particles are then subjected to ultrasonic treatment to produce nanoparticles. The produced protein particles have high potential to be used in nanocomposites and adsorbents.

Abstract: Surfactin is produced from Bacillus subtilis ssp. containing sfp gene (lipopeptide biosurfactants produced by fermentation). Production of surfactin at present is mainly by liquid fermentation, but the production costs are high due to difficulty in purification resulted from addition of the defoaming agent during the production process. Therefore, present invention conducts physical or chemical mutation on Bacillus subtilis subsp. isolated from Thailand seawater shrimp ponds and screens for the mutant strain of Bacillus subtilis subsp. based on sfp gene expression and then produces surfactin from the mutant strain by semi-solid state fermentation.

Abstract: The present invention provides a diagnostic reagent or assay for assessing the activity of a protease in vivo or in vitro and methods of detecting the presence of a cancerous or precancerous cell. The assays are comprised of two particles linked via an oligopeptide linkage that comprises a consensus sequence specific for the target protease. Cleavage of the sequence by the target protease can be detected visually or using various sensors, and the diagnostic results can be correlated with cancer prognosis.

Abstract: Methods and kits for characterizing liver damage in an individual are provided. The methods employ the use of immune analytes as biomarkers for detecting liver damage and predicting the likelihood that an individual suffering from liver damage will experience life-threatening liver failure. Concentration values for serum albumin and other identified immune analytes are obtained or determined from a blood sample taken from the individual. The obtained concentration values are then compared to corresponding concentrations from individuals having a healthy liver. By comparing the concentrations, an individual's likelihood of developing life-threatening liver failure and needing a liver transplant within a given time period (e.g., 6 months) can be identified.
