Immunoglobulin junctional diversity is concentrated in the third complementarity-determining region of the heavy chain (CDR-H3), which often plays a dominant role in antigen binding. The range of CDR-H3 lengths in mouse is shorter than in human, and thus the murine repertoire could be presumed to be a subset of the human one. To test this presumption, we(More)
Electrochemiluminescence (ECL) has been developed as a highly sensitive process in which reactive species are generated from stable precursors (i.e., the ECL-active label) at the surface of an electrode. This new technology has many distinct advantages over other detection systems: no radioisotopes are used; detection limits for label are extremely low (200(More)
The lake herring (Coregonus artedi) is an important coldwater planktivore in the Laurentian Great Lakes and in smaller inland lakes in portions of Canada and the northern United States. Lake herring cruise the pelagia and feed selectively in both gulping and particulate modes. They are visual predators in environments with adequate illumination. Visual(More)
In order to facilitate molecular analysis of antibody responses in Rhesus monkeys (Macaca mulatta), we used PCR techniques to clone and sequence the germline IGHD gene repertoire and the IGHD7–IGHJ6 locus in its entirety. We identified 30 distinct Rhesus DH genes belonging to seven subgroups and their recombination signal sequences that together share an(More)
The use of HLA class II-transgenic (Tg) mice has facilitated identification of antigenic T cell epitopes that may contribute to inflammation in T cell-mediated diseases such as rheumatoid arthritis and multiple sclerosis (MS). In this study, we compared the encephalitogenic activity of three DR2-restricted myelin determinants [mouse (m) myelin(More)
Rhesus macaques (Macaca mulatta) and chimpanzees (Pan troglodytes) are frequently used models for the study and treatment of human infectious diseases, including AIDS. Confidence in the equivalence to human of the humoral immune responses of these higher primates has grown as studies of immunoglobulin germline sequences have documented average identities of(More)
The mglA gene encodes a 22 kDa GTPase that is critical for single-cell (A) gliding, type IV pili-mediated (S) gliding and development of Myxococcus xanthus. To identify components that interact with MglA to control these processes, second-site mutations that restore movement to non-motile mglA mutants were sought. An allele-specific extragenic suppressor of(More)
Our previous studies demonstrated that oligomeric recombinant TCR ligands (RTL) can treat clinical signs of experimental autoimmune encephalomyelitis (EAE) and induce long-term T cell tolerance against encephalitogenic peptides. In the current study, we produced a monomeric I-A(s)/PLP 139-151 peptide construct (RTL401) suitable for use in SJL/J mice that(More)
We demonstrate the first use of an electrochemiluminescent (ECL) label, [4-(N-succimidyloxycarbonylpropyl)-4'-methyl-2,2'- bipyridine]ruthenium(II) dihexafluorophosphate (Origen label; IGEN Inc.), in DNA probe assays. This label allows rapid (less than 25 min) quantification and detection of polymerase chain reaction (PCR)-amplified products from oncogenes,(More)
The development of immunotherapy for prostate cancer based on the induction of autoimmunity to prostate tissue is very attractive because prostate is not a vital organ beyond the reproductive years. CD4 T cells play an important role in the development of antitumor immune responses, yet the identification of naturally processed MHC Class II-restricted(More)
