Antibodies with bound metal-chelate haptens provide new means for exploiting the diverse properties of metallic elements. The murine monoclonal antibody CHA255 (IgG1 lambda) binds the metal-chelate hapten indium (III)-4-[N'-(2-hydroxyethyl)thioureido]-L-benzyl-EDTA (designated In-EOTUBE) with high affinity (K(a) = 1.1 x 10(10) M-1). Antibody binding is(More)
Human pro-B-type natriuretic peptide (proBNP), the precursor for B-type natriuretic peptide (BNP), was expressed in Chinese hamster ovary cells (CHO) and compared by Western blot analysis to BNP cross-reacting material immunoprecipitated from the plasma of heart failure patients. Both recombinant and native forms co-migrated as a diffuse band centered(More)
We have developed a new method for obtaining information about protein sequences that uses an approach analogous to that used to determine DNA sequences. In essence, three steps are involved. First, a detectable label is attached exclusively to the amino terminus of a polypeptide. Next, the labeled chain is subjected to partial specific cleavage in a way(More)
An antibody (IgG1) was designed for oriented adherence to a metal-containing surface. This was achieved by adding a metal-chelating peptide, (CP = His-Trp-His-His-His-Pro), to the COOH-terminus of the heavy chain through genetic engineering. Electroporation of the engineered heavy chain gene into cells expressing the complimentary light chain yielded(More)
VEGF(121), the 121-amino acid form of vascular endothelial growth factor is a homodimer with nine cysteine residues per monomer. While three intramolecular and two intermolecular disulfide bonds have been mapped, the state of the ninth cysteine, Cys116, is not known. In this study, we determined that human VEGF(121) contains a third interchain disulfide(More)
The complete or partial sequences of 47 E. coli ribosomal proteins described in the literature have been examined by computerized search and matching programs. In contrast to results previously reported by other investigators, sequence homologies were uncovered among some of these ribosomal proteins that are well beyond statistical expectations. Moreover,(More)
The autoreactive T cell plays a pivotal role in the pathogenesis of type I diabetes in humans and in rodent animal models. Elimination or attenuation of these cells may provide a means to treat the disease. The use of antibodies directed to T cells has shown varying degrees of effectiveness in the treatment of autoimmune disease. The use of a bifunctional(More)
A simple method is described for the generation of a biologically produced mouse/human chimeric hetero-bifunctional antibody that has dual specificity for human carcinoembryonic Ag and metal chelate haptens. Two large compound chimeric vectors each containing the genetic information to produce a single antibody specificity were sequentially electroporated(More)
A new reagent for the routine identification of cysteine residues during protein sequencing is described. This method employs 3-bromopropylamine to alkylate cysteines in proteins after reduction with dithiothreitol. Upon sequencing of the protein on an Applied Biosystems 477A protein sequencer, the aminopropylcysteine residue yields a phenylthiohydantoin(More)
