Abstract: A freely-assembled ELISA plate is provided, including a first ELISA plate frame, a second ELISA plate frame, and ELISA plate strips located between the first ELISA plate frame and the second ELISA plate frame, collectively forming a liquid flow groove. The first ELISA plate frame is connected to a first side of the ELISA plate strips. A second side of the ELISA strips is connected to the second ELISA plate frame. The number of the ELISA plate strips in the ELISA plate can be determined according to the sample size, so that the waste of well resources of the ELISA plate can be effectively reduced; and, a desired amount of samples, washing buffer or the like can be added into the liquid flow groove once for all, so that the sample loading amount can be reduced and the detection speed can be quickened.

Abstract: An animal memory training system with a closed rotary maze comprises a maze device and a stimulating device. A rotary wheel (6) driven by a motor (4) is provided on the bottom of the case (1) of the maze device. The motor (4) is set in a central column, and its output shaft is tightly connected with the rotary wheel (6) along the central column shaft direction, thus the rotary wheel (6) is driven by the motor (4) to rotate around said central column. A number of pulleys (12) are set on the lower periphery of the frame of the case (1) to support said rotary wheel (6), and a sieve-like supporting net (5) is arranged above the rotary wheel (6). The stimulating device includes an automatic manipulator stimulating device and a remote control stimulating device. Compared with the existing maze model, the rotary drive action of the training system's rotary wheel is moderate, and is more coincident with the movement actual of animals' normal physiological behavior.
