A tubular structure for producing droplets and a method of using the tubular structure to produce droplets are provided. The tubular structure includes microchannel structures, and is used for droplet generation, droplet collection, nucleic acid amplification and/or in situ droplet detection, etc.

Tubular structure for producing droplets and method for producing droplets

A recombinant protein and a preparation method and application thereof are provided. The recombinant protein includes a peptide, and the peptide includes an amino acid sequence after substitution of the sequence of SEQ ID NO:. The substitution includes at least one selected from the group consisting of the following substitutions: the amino acid at position 182 of SEQ ID NO: 1 is substituted with aspartic acid (Asp); the amino acid at position 268 of SEQ ID NO: 1 is substituted with aspartic acid (Asp); and the amino acid at position 384 of SEQ ID NO: 1 is substituted with tyrosine (Tyr). The recombinant protein is suitable for detecting glycated hemoglobin.

Recombinant protein, and preparation method and application thereof

Apparatus for immunoassay includes: a cartridge, including at least one test unit; a pin-film assembly, having a second sealing film, a plurality of pierce mechanisms, and a first actuation unit; a plurality of magnetic particles; at least one first magnetic unit; and at least one second magnetic unit. The test unit includes a plurality of fluid chambers, a plurality of pin chambers, a microchannel structure, a buffer chamber, a detection chamber and a waste chamber. The first actuation unit drives the pierce mechanisms to enable a working fluid to flow into the detection chamber storing the magnetic particles. As the second magnetic unit has a magnetic force larger than that of the first magnetic unit and can move reciprocatingly between a third position and a fourth position, the magnetic particles are driven to move reciprocatingly inside the detection chamber, thereby fully mixing the magnetic particles with the working fluid.
