Shandong Agricultural University Describes Findings in Immunoglobulins

June 27, 2014

By a News Reporter-Staff News Editor at Energy Weekly News -- Investigators discuss new findings in Immunology. According to news reporting originating from Shandong, People's Republic of China, by VerticalNews correspondents, research stated, "In this work, we fabricated a novel photoelectrochemical immunosensor for assay of DNA methylation, where Bi2S3 nanorods were used as photoelectric conversion material, MBD1 protein (a kind of methyl bonding domain protein) was used as DNA methylation recognizing unit, anti-his tag antibody was used to further inhibit the photocurrent and increase the detection sensitivity. The results demonstrated that Bi2S3 possessed excellent photoelectron property."

Our news editors obtained a quote from the research from Shandong Agricultural University, "The detection conditions, such as Bi2S3 concentration, MBD1 protein concentration, incubation time of MBD1 protein, antibody concentration and antibody incubation time, were optimized. Under optimal experimental conditions, the photocurrent variation was proportional to the logarithm of methylated target DNA concentration from 10(-9) to 10(-13) M with detection limit of 3.5 x 10(-14) M (S/N=3)."

According to the news editors, the research concluded: "Moreover, the immunosensor presented high detection specificity, even distinguishing single-base mismatched sequence."
