Provided are a method for rapidly producing a calcium phosphate molded article having high strength with high shaping precision, a calcium phosphate molded article produced by the method, and a material for transplantation. Disclosed is a method for producing a calcium phosphate molded article, the method including: step (a) of forming a layer containing a calcium phosphate powder having a ratio of the numbers of atoms of Ca/P of 1.4 to 1.8 on a substrate; and step (b) of producing a calcium phosphate molded article by jetting an organic acid solution having a pH of 3.5 or lower and including an organic acid whose calcium salt has a solubility in water of 1 g/100 mL or less, through a nozzle unit into a liquid droplet state, thereby dropping the organic acid solution onto the layer containing a calcium phosphate powder formed in step (a).

It is an object of the present invention to provide a method capable of measuring a high concentration (up to 2500 U/L) of animal sample without dilutions, which is further capable of specifically measuring &#x3b1;-amylase even in a sample comprising animal &#x3b1;-amylase (EC 3.2.1.1) and glucoamylase (EC 3.2.1.3). The present invention provides a method for specifically measuring &#x3b1;-amylase contained in a non-human animal sample comprising &#x3b1;-amylase and glucoamylase without diluting said sample, wherein measurement is carried out by using an oligosaccharide having a protected nonreducing terminus and a p-nitrophenyl group at the reducing terminus thereof, and pH of reaction is 6 or more, and less than 7.
