The present invention is directed to monoclonal antibodies and fragments thereof for immunoreaction with organic compounds having a molecular size of no more than about 15 atoms in length and being a linear or branched aliphatic molecule or a small peptide. The invention is as well directed to hybridomas which produce the monoclonal antibodies, to immunogen compounds of the organic compound which cause development of the appropriate mammalian antibody response and to methods for producing antibody fragments. The invention is further directed to methods for detecting, removing, adding or neutralizing the organic compounds in biological and inanimate systems through the use of the monoclonal antibodies or fragments thereof.
摘要:
Cette invention concerne des procédés utilisant des microbes et des organismes plus évolués pour l'expression et la purification par affinité immobilisée par ligand d'un produit peptidique. Les compositions biologiques de cette invention qui sont réalisées à l'aide de ces procédés contiennent ou bien sont destinées à exprimer une structure de purification de protéine, ayant trois segments couplés en tandem composés d'une protéine de liaison, d'un peptide d'interconnexion et d'un polypeptide à fusion variable qui incorpore le produit peptidique dans une ou plusieurs copies. Suivant le procédé de l'invention, on obtient le produit peptidique comme suit: (a) on exprime une cellule hôte ou un organisme hôte de manière régulée par le vecteur d'expression recombinant portant le gène recombinant codant pour la structure de purification de protéine; (b) on purifie la structure de purification des protéines à l'aide d'une technique de séparation par affinité immobilisée par ligand; et (c) on effectue le clivage chimique ou enzymatique de la structure de purification de protéine pour produire le produit peptidique.
摘要:
L'invention concerne un moyen de fixation d'une marque, d'un support ou d'un agent bioactif à la protéine, sur un site éloigné du site actif de ladite protéine. Plus spécifiquement, l'invention concerne un procédé de fixation d'un acide aminé, d'un dérivé d'acide aminé, d'une amine et d'un nucléophile d'alcool à la terminaison carboxyle d'une protéine. Selon un mode de réalisation, on utilise une enzyme d'exopeptidase afin de fixer un nucléophile marqué à une protéine telle qu'un anticorps. Selon d'autres modes de réalisation, l'invention concerne un procédé de fixation d'une protéine à un support d'immobilisation, ainsi qu'un procédé de fixation d'un agent bioactif à une protéine.
摘要:
Methods and kits for determining whether an individual is susceptible to developing impaired glucose tolerance (IGT), impaired fasting glucose (IFG), or Type-2 diabetes are described. Such methods include administering GIP or GIP variant and nutrient to an individual, measuring the response of the individual and determining whether the individual is susceptible to developing IGT, Type-2 diabetes, or IFG.
摘要:
A pharmaceutical composition for administration to a mammal is disclosed. The composition includes a therapeutically effective amount of a peptide, such as a GLP-1 molecule, a PTH molecule, or a GRF molecule. The composition further includes a buffer including a weak acid having an acid dissociation constant value of greater than about 1x10-5, such as acetic acid. The composition also includes an excipient for making the composition generally isotonic, such as D-mannitol.
摘要:
The present invention is directed to microbial and higher organism methods for expression and ligand immobilized affinity purification of a product peptide. The biological compositions of the invention which are produced by these methods include or are designed to express, a protein purification construct having three tandem, coupled segments composed of a binding protein, an interconnecting peptide and a variable fused polypeptide which incorporates the product peptide in one or more copies. According to the method of the invention, the following steps will allow production of the product peptide: (a) host cell or host organism expression regulated by the recombinant expression vector carrying the recombinant gene coding for the protein purification construct; (b) purification of the protein purification construct by a ligand immobilized affinity separation technique; and (c) enzymatic or chemical cleavage of the protein purification construct to produce the product peptide.
