  • Publication number: 20090029393
    Abstract: The present invention relates to a method for preparing an antibody selective for activating antibody Fc region receptors (FcRs) comprising an ITAM motif or motifs (immunoreceptor tyrosine-based activation motif), comprising the steps of obtaining monoclonal antibodies from a hybridoma, from a heterohybridoma or from any animal, plant or human cell line, replacing each of the His 310 and His 435 residues (Cabat numbering) of the Fc region of said antibody with a residue chosen from lysine, alanine, glycine, valine, leucine, isoleucine, proline, methionine, tryptophan, phenylalanine, serine or threonine, and then selecting the antibodies for which the binding to inhibitory FcRs comprising ITIM motifs (immunoreceptor tyrosine-based inhibition motif) is decreased by at least 30%, preferably by at least 50%, 70%, 80% or else by at least 90% relative to the same antibody having a natural Fc region.

  • Patent number: 5891699
    Abstract: Modified alkaline phosphatases of bacterial origin (BAP or bacterial alkaline phosphatase) which consist of a bacterial alkaline phosphatase sequence in which at least one of the amino acid residues in position 329 or in position 330 is replaced by another amino acid residue, which modified bacterial alkaline phosphatases exhibit both significantly improved enzymic properties and an increased thermal stability, and their applications, in particular in immunoenzymic assays (reagents and diagnostic kits).Method for selecting mutants of alkaline phosphatases which possess significantly improved enzymic properties.

  • Patent number: 5534223
    Abstract: A kit for carrying out an immunoenzymological assay for protein, containing a diagnostic reagent consisting of a hybrid protein comprising, in order, a polypeptide P1 which is an N-terminal portion of mature alkaline phosphatase comprising from 6 to 28 of the N-terminal amino acids of said mature alkaline phosphatase, joined to a polypeptide P2, capable of interacting with an antibody or antigen joined to a polypeptide P3 which is selected from the group consisting of a) the C-terminal remaining amino acids of said mature alkaline phosphatase, b) the mature sequence of alkaline phosphatase, and c) enzymatically active fragments of b).

  • Patent number: 5362644
    Abstract: The disclosed invention involves a DNA encoding a hybrid tripartite protein comprising an amino portion consisting of from 6 to 28 amino acid residues from the N-terminal of a mature E. coli alkaline phosphatase, a central portion corresponding to a heterologous polypeptide and a carboxyl portion which consists of the remainder of the mature E. coli alkaline phosphatase, a different alkaline phosphatase or an enzymatically active fragment of either. The tripartite proteins produced with this DNA can be used as a diagnostic reagent and in the screening of nucleic acid libraries or in the selection of recombinant clones.
