12 Analytical characteristics of ICAT-LC-MS/MS for quantitative proteomics studiesRecent studies have employed isotope-coded affinity tags (ICAT) in concert with tandem mass spectrometry (MS/MS) to assess differential expression of proteins on a proteomic scale and perform unbiased quantitative comparisons between samples from different physiological or disease states. We sought ...isotope-coded affinity tags; ICAT; mass spectrometry; MS/MS; proteomic scale; FL2005-06-03
13 Multiplex analysis of heterophil antibodies in patients with indeterminate HIV immunoassay resultsWe hypothesized that heterophil antibodies reactive with animal proteins used in blot preparation caused nonspecific staining (NSS) on HIV Western blot (WB) studies, causing indeterminate results. We analyzed samples showing NSS on HIV WB using a multiplexed immunoassay to simultaneously measur...Heterophil antibodies; Heterophil interference; Multiplex analysis; False-positive HIV enzyme-linked immunosorbent assay; ELISA2001
14 Comparison of four enzyme immunoassays with a western blot assay for the determination of type-specific antibodies to herpes simplex virusMost current enzyme immunoassays (EIAs) differentiate inadequately between types 1 and 2 herpes simplex virus (HSV) antibodies since significant crossreactivity exists. We compared 4 IgG type-specific EIAs using a Western blot assay for resolution of discrepant results. The Diamedix had sensitivit...Enzyme immunoassays; Western blot assay; Type-specific antibodies2001
15 Alveolar rhabdomyosarcomas in conditional Pax3:Fkhr mice: cooperativity of Ink4a/ARF and Trp53 loss of function.Alveolar rhabdomyosarcoma is an aggressive childhood muscle cancer for which outcomes are poor when the disease is advanced. Although well-developed mouse models exist for embryonal and pleomorphic rhabdomyosarcomas, neither a spontaneous nor a transgenic mouse model of alveolar rhabdomyosarcoma has...Cell Differentiation; Forkhead Transcription Factors; Myogenic Regulatory Factors2004-11-01
16 Nucleic acid vaccine encoding gD2 protects mice from herpes simplex virus type 2 disease.Nucleic acid vaccinations with plasmids pWW65, containing the sequence for herpes simplex type 2 (HSV-2) gD2, and pRSVnt, lacking the gD sequence, were studied. Groups of mice were immunized with pWW65 alone, pWW65 plus 1,25-dihydroxyvitamin-D3 (D3), or pRSVnt. Clinical disease (vaginitis), serum an...Mice, Inbred BALB C; Plasmids; Viral Vaccines1996
17 Masking techniques: masking selected sequence variation by incorporating mismatches into melting analysis probesHybridization probe melting analysis can be complicated by the presence of sequence variation (non-pathogenic polymorphisms or other mutations) near the targeted mutation. We investigated the use of 'masking' probes to differentiate alleles with similar probe melting temperatures.
