DNA microarray, also known as DNA array or DNA chip, is a special glass or silicon chip with DNA microarray. Tens of thousands of nucleic acid probes are placed on an area of several square centimeters. After the DNA, cDNA, RNA, etc. in the sample are combined with the probe, it is detected by fluorescence or electric current. Through one test, a large amount of gene sequence-related information can be provided. cDNA Chips custom service https://microfluidics.alfa-chemistry.com/cdna-chips.html
