Sample adding device

Abstract

The invention discloses a sample adding device, which comprises a three-axis manipulator and a liquid suction and injection apparatus. The three-axis manipulator comprises a first X-axis mechanical arm, a first Y-axis mechanical arm connected to the first X-axis mechanical arm, and a first Z-axis mechanical arm perpendicular to the first X-axis mechanical arm and the first Y-axis mechanical arm. The liquid suction and injection apparatus comprises a pipettor and a syringe pump, the pipettor is communicated with the syringe pump through a duct, and the pipettor is fixed at the bottom end of thefirst X-axis mechanical arm. The three-axis manipulator is electrically connected to a control board. The sample adding device provided by the invention can realize automatic sample adding, has no need for manual sampling, improves the work efficiency and reduces the contamination of manual operation to samples.

Description

technical field [0001] The invention belongs to the technical field of automatic medical equipment detection, in particular to a sample adding device. Background technique [0002] Western blotting (immunoblotting test) is Western Blot. It is an experimental method commonly used in molecular biology, biochemistry and immunogenetics. The basic principle is to stain cells or biological tissue samples processed by gel electrophoresis with specific antibodies. Information on the expression of a specific protein in the cell or tissue being analyzed is obtained by analyzing the location and depth of staining. Western blot (Western Blot) is a protein detection technology that transfers the total proteins of cells or tissues separated by electrophoresis from a gel to a solid support NC membrane or PVDF membrane, and then uses a specific antibody to detect a specific antigen. It has been widely used in gene expression research at the protein level, antibody activity detection and ...

Problems solved by technology

At present, there are two types of Western blot detection: manual detection and instrument detection. The manual detection method needs to replace different reagents, frequent operations increase the work intensity of the experimenter and waste time, and the manual operation is cumbersome and complicated. There is a lot of contact with potentially infectious items, and the detection safety is poor; although the western blot detection instruments currently used in clinical practice are called "automatic", they are not fully automated, and manual sample addition and interpretation are required
