Reagents for detecting antigen contained in body fluid or urine according to the immunological agglutination or agglutination inhibition reaction and comprising an antibody adsorbed on fine carrier particle to be sensitized as an effective constituent, and is characterized by acylating said antibody. Owing to such acylation, the reagent can correctly detect antigen without any influence of substance contained in sample which has inevitably caused nonspecific agglutination reaction according to the prior art.

Fine carrier particles sensitized with acylated antibody for antigen

Human urine-origin colony-stimulating factor and kallikrein are separated in pure form, respectively, from an aqueous solution thereof, such as a urinary protein-concentrated solution by subjecting the solution added with a stabilizer such as octyl-phenoxypolyethoxyethanaol or polyethylene glycol both having a molecular weight of 1,000-10,000, to high-performance gel filtration effective in molecular exclusive limit of 10.sup.5 -5.times.10.sup.5 as determined with globular protein.

Method of preparation of human urine origin colony-stimulating factor

A colony stimulating factor effective in treating human granulocytopenia is produced by cultivating monocytes and macrophages isolated from the human peripheral blood in a synthetic medium for tissue culture containing a glycoprotein isolated from human urine and capable of stimulating the formation of human granulocytes or mouse macrophages and granulocytes.

Method for producing substance capable of stimulating differentiation

A method of manufacturing a packaged soybean curd with a long shelf life without the inclusion of any artificial additives such as coagulating agents, germicides and the like; wherein soybean juice is subjected to lactic acid fermentation until its pH is reached to a value equal to or less than a value which is determined from the percentage of the solids content (5-16 wt. %) of soybean juice and then is subjected to heating (60.degree.-95.degree. C., 10-100 minutes) to adjust the curd tension to above 20 g.

A colony-stimulating factor having definite physical and chemical properties and a function of stimulating activity on human bone marrow cells to proliferate and differentiate, thereby forming granulocyte colonies, is obtained from human urine by concentrating the urine with respect to proteins contained therein by adsorption chromatography with silica gel, salting out with ammonium sulfate and other means, then removing impurities by adsorption on cation exchanger, and further purifying by ion exchanging chromatography on anion exchanger, gel filtrating chromatography with highly crosslinked gels, affinitive chromatography with sugar affinitire adsorbents and electrophoresis.

A colony-stimulating factor having definite physical and chemical properties and a function of stimulating activity on human bone marrow cells to proliferate and differentiate, thereby forming granulocyte colonies, is obtained from human urine by concentrating the urine with respect to proteins contained therein by adsorption chromatography with silica gel, salting out with ammonium sulfate and other means, then removing impurities by adsorption on cation exchanger, and further purifying by ion exchanging chromatography on anion exchanger, gel filtrating chromatography with highly crosslinked gels, affinity chromatography with sugar affinitive adsorbents and electrophoresis. This substance is stable in the presence of a stabilizer such as albumin or urinary proteins, against heat-treatment of virus-inactivation and can be used as a leukopenia curative which is precluded from fear of virus-infection.

Latex reagents for quantitative assay of a variety of steroid hormones or metabolites thereof which are contained in body fluid or excreted fluid of human beings comprise latex particles which are immunologically sensitized with a conjugate selected from a variety of steroid-serum albumin conjugates in which the steroid to be detected is bonded to serum albumin in a very small ratio ranging from 0.5 to 7 molecules per 1 molecule of the serum albumin used. Sensitization of latex particles with such a conjugate is performed using a limited amount dependent on the bonding ratio of steroid molecules per molecule of serum albumin in the conjugate and the particle size of the latex used. The latex reagents show very high sensitivity amounting to 0.2-0.04 nmole steroid equivalent/ml.

A process for preparing a therapeutic agent characterized by preculturing human amnion cells isolated from human amnion by trypsinization or human amnion cells obtained by subculturing the isolated cells in a medium containing calf or bovine fetal serum at least one time for 1 to 5 days to form a monolayer, removing the medium, adding a medium containing 0.5 to 20 mg of human serum albumin per 1 ml of medium thereto and culturing it for 3 to 6 days, dialyzing the culture liquid against diluted buffer or water, and filtering the dialyzed culture liquid through a bacterial filter thereby obtaining a germ free liquid agent.
