摘要:
The present invention is directed to a monoclonal antibody against a soluble fibrin, which specifically recognizes a conformation-changed site newly occurred in a C-terminal region of an Aα-chain of the soluble fibrin formed through thrombin digestion of fibrinogen. The present invention is also directed to a hybridoma which produces the antibody, an immunological assay method employing the antibody, and a method for evaluating hypercoagulability in a test sample by measuring the soluble fibrin level in the sample with the assay method. Through employment of the monoclonal antibody of the present invention, soluble fibrin on which plasmin has not acted, which reflects exclusively initial hypercoagulability, can be specifically detected.
摘要:
Therapeutic compositions can include modified peptides which are derived from the chain of the Bbeta(15-42)-fibrin fragment and wherein one or several of the amino acids of the sequence have been substituted by genetically encoded or not genetically encoded amino acids or peptidomimetics. They may exist as free peptides or as C-terminal derivative and/or being linked to a polyethylene glycol (PEG)-polymer, and have anti-inflammatory and/or endothelium stabilizing effects. Esters or amides may for instance be taken into consideration as C-terminal derivatives. Processes for production of the peptides and derivatives thereof are also described.
摘要:
The present invention concerns a chimeric polypeptide, capable of detecting the antibodies generated in rheumatoid arthritis, comprising at least two citrulinated peptide subunits: (i) one derived from the α or β chain of the fibrin and (ii) a second derived from the filaggrin. In addition, the invention comprises an antigenic composition, a method and a kit for the diagnosis of rheumatoid arthritis, from the detection of the autoantibodies generated during the course of said disease.
摘要:
Methods for producing porous freeze-dried fibrin matrices substantially devoid of external anti-fibrinolytic agents. Resilient matrices, also known as sponges, that are particularly beneficial for supporting three dimensional cell growth are obtained from plasma proteins substantially devoid of plasminogen or from partially purified plasma proteins, thus obviating the need for exogenous anti-fibrinolytic agents. Furthermore, incorporation of glycosaminoglycans and bioactive agents during the formation of the matrix results in a sponge having advantageous biological, mechanical and physical properties. The compositions made by the processes of the present invention are useful clinically, per se or as cell-bearing implants.
摘要:
When genes encoding three kinds of proteins constituting fibrinogen, an α chain (or variant of α chain), a β chain and a γ chain (or variant of γ chain) are incorporated into an animal cell, a constitutional ratio of respective genes is such that a γ chain (and/or variant of γ chain) gene is an equal amount to a 1000-fold amount relative to an α chain (and/or variant of α chain) gene and a β chain gene and, further, by using a baculovirus P35 gene, a recombinant fibrinogen highly producing cell is prepared.

摘要:
Biocompatible crosslinked polymers, and methods for their preparation and use, are disclosed in which the biocompatible crosslinked polymers are formed from water soluble precursors having electrophilic and nucleophilic functional groups capable of reacting and crosslinking in situ. Methods for making the resulting biocompatible crosslinked polymers biodegradable or not are provided, as are methods for controlling the rate of degradation. The crosslinking reactions may be carried out in situ on organs or tissues or outside the body. Applications for such biocompatible crosslinked polymers and their precursors include controlled delivery of drugs, prevention of post-operative adhesions, coating of medical devices such as vascular grafts, wound dressings and surgical sealants. Visualization agents may be included with the crosslinked polymers.
