Spotting system

Abstract

The invention discloses a sample application system, which comprises a glass slide storage unit, a sample application unit and a transfer unit, wherein the glass slide storage unit is used for storing a glass slide; the sample application unit comprises a sample application platform used for placing the glass slide and a sample applicator used for carrying out sample application on the glass slide placed on the sample application platform; the transfer unit comprises a transition device and a transfer device; the transition device comprises two transition platforms which are located in a first transition area and a second transition area respectively; the transfer device comprises a first transfer device and a second transfer device; the first transfer device grabs the glass slide and transfers the glass slide between the glass slide storage unit and one of the two transition platforms; the second transfer device grabs the glass slide and transfers the glass slide between the sample application unit and the other of the two transition platforms; the two transition platforms are linked; when one of the two transition platforms is moved from the first transition area to the second transition area, the other of the two transition platforms is moved from the second transition area to the first transition area.

Description

technical field [0001] The invention provides a spotting system, in particular to a spotting system for a biochip. Background technique [0002] Gene chip (also known as DNA chip, biochip) technology refers to immobilizing a large number of probe molecules (usually higher than 400 per square centimeter lattice density) on a support and then hybridizing with labeled sample molecules. The hybridization signal intensity of the molecules can be used to obtain the number and sequence information of the sample molecules. In layman's terms, it is to regularly arrange and fix tens of thousands or even millions of DNA fragments (gene probes) of specific sequences on supports such as thin films and glass slides through micro-processing technology. At present, the probe spotting technology is generally realized by a biochip spotting instrument, and the spotting process needs to place a slide on the spotting platform and remove the slide on the spotting platform and place it in a prede...

Problems solved by technology

At present, the probe spotting technology is generally realized by a biochip spotting instrument, and the spotting process needs to place a slide on the spotting platform and remove the slide on the spotting platform and place it in a predetermined position , so it is necessary to transfer the slides between predetermined areas. In addition, labels for displaying information need to be attached to the slides. At present, the slides are usually transferred manually, which is not only slow and inefficient. , cannot meet the production needs of industrialized gene chips, and it is easy to cause damage to the glass slides. In addition, after the sample is placed, it is necessary to attach labels to the glass slides, which also requires manual methods, and also faces the above problems
