Provided are a magnetic bead-based detection method, a storage medium, and a detection device. The detection method includes: collecting a white light image of a to-be-detected solution, in which the to-be-detected solution is mixed with a to-be-detected sample and magnetic beads with a capture agent (S); determining magnetic stripe regions in the white light image, and determining first magnetic bead regions based on the magnetic stripe regions (S); selecting, by using a first neural network, second magnetic bead regions containing magnetic beads from the first magnetic bead regions, and obtaining a marker position of each of the magnetic beads (S); and obtaining, by using a second neural network and based on each of the second magnetic bead regions, codes at code bits of a corresponding magnetic bead, and obtaining corresponding code information based on the codes of the code bits and the marker position of the magnetic bead (S).

Magnetic bead-based detection method, storage medium, and detection device

A method for obtaining a single-cell mRNA sequence, including: (1) capturing mRNA of a cell by using a cell tag carrier, and performing reverse transcription to obtain cDNA having a cell tag; (2) obtaining multiple cDNA fragments having molecular tags by using a transposase complex and a molecular tag carrier; (3) performing high-throughput sequencing; (4) performing sequence assembly according to the molecular tags to obtain the sequence of each mRNA; and () obtaining the sequence of all mRNAs of each single cell according to the cell tags.
