This invention discloses a high-throughput automated immunofluorescence staining device and its staining method. The device includes a liquid injection motion module, a reaction chamber module, a supply and waste collection module, and a control system. The liquid injection motion module includes an X-axis beam and a pipetting and auxiliary material robotic arm, which are driven in parallel to achieve sequential operation. The reaction chamber module includes a temperature-controlled station, a low-temperature reagent storage unit, and an auxiliary material supply unit. The supply and waste collection module includes a waste removal and cleaning unit and an auxiliary material waste collection unit. This invention achieves a 96-station array through a temperature-controlled reaction station, combined with the dual-drive parallel operation of the pipetting and auxiliary material robotic arms, eliminating action waiting time and significantly improving throughput. The use of a closed semiconductor cooling component linked with an automatic flip-top mechanism ensures uniform reagent activity over a long period. A plate-mounted small vacuum pump drives a rigid pipeline with deep-hole waste suction, combined with high-flow-rate wide-area spraying, to thoroughly remove waste liquid and reduce cross-contamination. This achieves full-process automation, significantly improving staining quality and efficiency.

The invention discloses a full-automatic immunofluorescence slide staining system and method, and relates to the technical field of slide staining machines.

Cooperative operation of all the modules is planned through a central control system, a full-process automatic closed loop from sample code scanning, dilution, incubation, cleaning, secondary antibody loading to sheet sealing, fluorescence imaging and preliminary interpretation is formed, the limitation of traditional manual operation and function fragmentation of existing equipment is thoroughly eliminated, all experiment links do not need to be connected manually, and the working efficiency is improved. The manual dependence degree is obviously reduced, and the detection efficiency of large-batch samples is effectively improved.

This invention provides a fully automated immunoassay analyzer, comprising: a base, a reaction disk for carrying multiple immunochromatographic test strips installed inside the base, a sample processing area for processing samples installed on the base, and a moving arm assembly movably installed on the base for driving a pipette arm to perform liquid pipetting, mixing, and spotting operations in the sample processing area. Compared with the prior art, this invention has the following advantages: by setting up the moving arm assembly, in conjunction with the pipette arm and negative pressure nozzle, its automated operation can simultaneously perform multiple sample single detection, single sample multiple detection, or multiple sample multiple detection, with high throughput, making up for the insufficient throughput of existing manual experiments. Automated sample pretreatment and automatic recycling of waste after experiments avoid manual errors and are convenient and pollution-free.

This invention discloses a fully automated immunofluorescence staining system and method, relating to the field of staining machine technology. The system includes an operating table equipped with a central control system and, through signal interaction with the central control system, a sample processing module, a reagent loading module, a cleaning needle module, a mounting module, a fluorescence imaging module, and an antigen loading module. The sample processing module is configured with several independent sample needle modules, each equipped with an independent Z-axis drive mechanism and an independent Y-axis drive mechanism. The central control system coordinates the operation of all modules, forming a fully automated closed loop from sample scanning, dilution, incubation, cleaning, secondary antibody loading to mounting, fluorescence imaging, and preliminary interpretation. This completely eliminates the limitations of traditional manual operation and the fragmented functionality of existing equipment, eliminating the need for manual coordination between experimental steps, significantly reducing reliance on manual labor, and effectively improving the detection efficiency of large batches of samples.

The invention relates to the technical field of medical detection, in particular to an antibody combination for detecting spermatogenic cells, a kit and application of the antibody combination. The antibody combination comprises an antibody of a zinc finger transcription factor 4, an antibody of a conjugation complex protein 3 and an antibody of zona pellucida binding protein. Specific recognition and semi-quantitative analysis of spermatogenic cells of all levels in samples are realized through standardized pretreatment, full-automatic immunohistochemical staining and digital image analysis for different types of samples; the method breaks through the technical bottlenecks that the traditional HE staining or Wright-Giemsa staining method is strong in subjectivity, difficult to distinguish cells with similar forms and greatly influenced by cell states and staining effects, and provides an efficient detection means for accurate pathological typing, spermatogenic function evaluation and dynamic curative effect monitoring of male infertility.

The invention discloses a multi-channel parallel detection method of a full-automatic immunoblotting instrument, and relates to the field of biotechnology detection. The problems that a traditional immunoblotting method needs multiple incubation, operation is tedious and time-consuming, and signal crosstalk and inaccurate quantification are caused by emission spectrum overlapping of a multi-standard method based on spectrum distinguishing are solved. The method comprises the following steps: preparing a marker combination with mutually distinguished fluorescence lifetime, carrying out one-time synchronous incubation combination, carrying out pulse laser scanning excitation, collecting signals in a discontinuous time gate by adopting time gate control detection to obtain a four-dimensional detection data set, and finally carrying out decoupling operation based on known fluorescence lifetime characteristics to obtain a four-dimensional detection result. And a super-resolution protein distribution diagram is further generated through regularization optimization, and signal separation is realized according to life difference, so that super-resolution quantitative expression quantity distribution of each target protein is synchronously obtained in one-time detection, high-throughput and high-accuracy multi-target protein parallel detection is realized, and spectral crosstalk is effectively avoided.
