Abstract: L'invention concerne une mesure de cellules entières permettant une quantification directe de l'activité de la protéine tyrosine phosphatase (PTP), cette mesure utilisant un système d'expression à baculovirus. Une PTP exprimée dans des cellules hôtes d'insectes transformées est traitée puis localisée dans les compartiments sous-cellulaires prévus. Les mesures sont effectuées sur des cellules hôtes qui expriment cette PTP et sont stimulées par un substrat comme le phosphate de p-nitrophényle, ce substrat étant hydrolysé en p-nitrophénol par l'activité de phosphatase exprimée. L'apparition de p-nitrophénol est déterminée par une détection spectrophotométrique et constitue une mesure de l'activité PTP. De plus, la mesure et les cellules hôtes transformées de cette invention sont particulièrement utiles dans un procédé de criblage destiné à sélectionner des inhibiteurs potentiels desdites PTP. Les cellules hôtes transformées sont pré-incubées avec ou sans des inhibiteurs, et la mesure est effectuée comme décrit précédemment.

Abstract: The oxides-enclosed fine glass particles are arranged such that two or more pieces of at least two kinds of enclosing particles, which comprise oxides, double oxides, or salts of oxyacids, or double oxides or double salts thereof, are enclosed in each of the fine glass particles.  The fine particles can be easily manufactured by mixing a powder material of glass with a powder material of oxides which comprise oxides, double oxides, or salts of oxyacids, or double oxides or double salts thereof that are not made to glass; converting the thus obtained mixture of the materials into a mixture in a vapor-state by supplying the thermal plasma thereto; and quickly cooling the mixture in the vapor-state. Highly-scattered fine particles of oxides can be easily obtained from the fine particles, and thus a plurality of kinds of fine particles of oxides can be evenly and uniformly mixed in a small amount with a mother material without being unevenly scattered.
