A method for fabricating uni-dsDNA microarray chip for analyzing DNA-binding proteins
چکیده انگلیسی
This paper describes an approach for preparing unimolecular double-stranded DNA (uni-dsDNA) microarray chip. In this method, the various target oligonucleotides containing a reverse complementary sequence at 5′ end were firstly annealed to a same universal oligonucleotide with amino group at 5′ end and immobilized on aldehyde-derivatized glass slide. An on-chip DNA polymerization reaction was then performed to elongate the universal oligonucleotides. After a denaturation and a followed intra-strand annealing, a hairpin structure was formed at the free 3′ end of the immobilized oligonucleotides. Finally, another on-chip DNA polymerization was done to synthesize the uni-dsDNA microarray. Combining with a PCR amplification of chemically synthesized target oligonucleotides, this method was much cost-effective for production of the uni-dsDNA microarray. The uni-dsDNA microarray was verified applicable for detecting the presence and monitoring the DNA-binding activity of the sequence-specific DNA-binding proteins.
