A method of producing a microproduct comprises: providing a resin composition including 30 to 90 wt % of a polypropylene-based resin and 10 to 70 wt % of a hydrogenated derivative of a block copolymer shown by 'X-Y' (X represents a polymer block immiscible with the polypropylene-based resin, Y represents an elastomeric polymer block of a conjugated diene that's miscible with the polypropylene-based resin after hydrogenation); attaching a silicon stamper to a mold cavity of an injection molding machine, the silicon stamper having micromachined features formed by etching the surface of a silicon plate; and precisely transferring the micromachined features of the silicon stamper to the resin composition by injecting the resin composition into the mold cavity, a resulting molded surface having recesses and/or protrusions that are 0.3 to 200 &#x3bc;m deep or tall and 0.3 to 100 &#x3bc;m wide.

Method of producing a microproduct

A microwell array chip that has multiple microwells and is employed to contain a single lymphocyte specimen in each microwell and detect antigen-specific lymphocytes in single units; wherein the microwell array chip is of a shape and of dimensions where only one lymphocyte is contained in each microwell. A method of detecting antigen-specific lymphocytes comprising the steps of adding antigen to each microwell in the above microwell array chip, stimulating the lymphocyte specimen, and detecting lymphocyte specimens reacting with the antigen.

Microwell array chip for detecting antigen-specific lymphocytes, method of detecting and method of manufacturing antigen-specific lymphocytes, and method of cloning antigen-specific lymphocyte antigen receptor genes
