The density of snp detection technology is high.
SNP technique: First, a fragment of the genome containing a single nucleotide polymorphism is amplified by polymerase chain reaction (PCR), followed by single base amplification with sequence-specific primers. The sample analytes are then co-crystallized with the chip matrix and excited in a vacuum tube with a transient nanosecond (10-9s) laser. Gene chip: The principle of sequencing is hybridization sequencing, that is, a nucleic acid sequencing method of hybridization of a set of nucleic acid probes with known sequences.
