Publication number: 20110086435Abstract: A method for determining the dissociation constant (Kd) by plotting resonance frequency shift as a function of time for various target analyte concentrations. From this graph, the fraction of saturation, i.e. equilibrium fraction of bound binding sites out of all available binding sites on the sensor surface may be estimated by taking the ratio of the equilibrium resonance frequency shift at a selected concentration to the equilibrium frequency shift of the sensor. The dissociation constant is the inverse slope of the line produced by graphing the fraction of saturation as a function of concentration. This method is particularly useful for the study of protein-protein and protein-mRNA interactions.Type: ApplicationFiled: October 7, 2010Publication date: April 14, 2011Applicant: DREXEL UNIVERSITYInventors: WAN Y.

Publication number: 20110086436Abstract: A method for detecting an antigen, an apparatus for detecting an antigen using the same, and a microfluidic chip using the same are disclosed. The method for detecting an antigen, includes: binding a first antibody and nano-beads to generate antibody nano-beads; binding the generated antibody nano-beads and an antigen to generate antigen-antibody nano-beads; forming at least one of an electric field and a magnetic field on the generated antigen-antibody nano-beads to bind the generated antigen-antibody nano-beads and a second antibody; and detecting the antigen-antibody nano-beads bound to the second antibody. Thus, when nano-beads affected by an electromagnetic field exist within the electromagnetic field that temporally and spatially changes, the nano-beads move according to non-uniformity of the electromagnetic field. In particular, an active mixing can be performed by using the electromagnetic field which is spatially non-uniform and changes temporally, a reaction time can be reduced.Type: ApplicationFiled: October 7, 2010Publication date: April 14, 2011Applicant: Electronics and Telecommunications Research InstituteInventor: Nam Soo MYUNG

Publication number: 20110086437Abstract: A novel gene 109P1D4 and its encoded protein, and variants thereof, are described wherein 109P1D4 exhibits tissue specific expression in normal adult tissue, and is aberrantly expressed in the cancers listed in Table I. Consequently, 109P1D4 provides a diagnostic, prognostic, prophylactic and/or therapeutic target for cancer. The 109P1D4 gene or fragment thereof, or its encoded protein, or variants thereof, or a fragment thereof, can be used to elicit a humoral or cellular immune response; antibodies or T cells reactive with 109P1D4 can be used in active or passive immunization.Type: ApplicationFiled: October 28, 2010Publication date: April 14, 2011Inventors: Arthur B.

Publication number: 20110086438Abstract: Systems and methods for detecting the presence of biomolecules in a sample using biosensors that incorporate resonators which have functionalized surfaces for reacting with target biomolecules. In one embodiment, a device includes a piezoelectric resonator having a functionalized surface configured to react with target molecules, thereby changing the mass and/or charge of the resonator which consequently changes the frequency response of the resonator. The resonator's frequency response after exposure to a sample is compared to a reference, such as the frequency response before exposure to the sample, a stored baseline frequency response or a control resonator's frequency response.Type: ApplicationFiled: December 14, 2010Publication date: April 14, 2011Inventors: Yuegang ZHANG, Andrew BERLIN, Qing MA, Li-Peng WANG, Valluri RAO, Mineo YAMAKAWA
