A porous &#x3b2;-tricalcium phosphate material for bone implantation is provided. The multiple pores in the porous TCP body are separate discrete voids and are not interconnected. The pore size diameter is in the range of 20-500 &#x3bc;m, preferably 50-125 &#x3bc;m. The porous &#x3b2;-TCP material provides a carrier matrix for bioactive agents and can form a moldable putty composition upon the addition of a binder. Preferably, the bioactive agent is encapsulated in a biodegradable agent. The invention provides a kit and an implant device comprising the porous &#x3b2;-TCP, and a bioactive agent and a binder. The invention also provides an implantable prosthetic device comprising a prosthetic implant having a surface region, a porous &#x3b2;-TCP material disposed on the surface region and optionally comprising at least a bioactive agent or a binder. Methods of producing the porous &#x3b2;-TCP material and inducing bone formation are also provided.

The present invention provides compositions comprising at least one complement moiety and at least one carbohydrate moiety, and methods of producing such compositions. In particular, the compositions of the invention comprise complement proteins related to the complement receptor type 1, and further comprise ligands for intercellular molecules, such as selectins. In a preferred embodiment, the compositions comprise a complement-related protein in combination with the Lewis X antigen or the sialyl Lewis X antigen. The compositions of the invention have use in the diagnosis or therapy of disorders involving complement activity and inflammation. Pharmaceutical compositions are also provided for treating or reducing inflammation mediated by inappropriate complement activity and intercellular adhesion.

Compositions comprising complement receptor type 1 molecules having carbohydrate structures that are selectin ligands

A method is disclosed for treating diseases or disorders involving complement by pulmonary administration of complement inhibitory proteins such as soluble complement receptor type 1 (sCR1). The present invention relates to the direct treatment of certain complement related disorders by administering complement inhibitory proteins via the pulmonary route, in particular, by direct delivery to the lungs by aerosolization of a complement inhibitory protein and subsequent inhalation.

Pulmonary administration of soluble complement receptor-1 (sCR1) and its derivatives

The present invention provides compositions comprising at least one complement moiety and at least one carbohydrate moiety, and methods of producing such compositions. In particular, the compositions of the invention comprise complement proteins related to the complement receptor type 1, and further comprise ligands for intracellular molecules, such as selectins. In a preferred embodiment, the compositions comprise a complement-related protein in combination with the Lewis X antigen or the sialyl Lewis X antigen. The compositions of the invention have use in the diagnosis or therapy of disorders involving complement activity and inflammation. Pharmaceutical compositions are also provided for treating or reducing inflammation mediated by inappropriate complement activity and intercellular adhesion.

Compositions comprising complement related proteins and carbohydrates,

Disclosed is a protein that specifically binds carcinoembryonic actigen (CEA) in the presence of divalent cation in vitro. This protein has a molecular weight of about 20 kD as determined by SDS-polyacrylamide gel electrophoresis, is glycosylated, and includes the amino acid sequence set forth in the Sequence Listing as SEQ ID NO:4. Also disclosed are antibodies that recognize the CEA binding protein, methods of detecting carcinoma, methods of treating carcinoma, and a kit for screening a patient for carcinoma.

CEA-binding protein and uses thereof

Disclosed is a protein that specifically binds carcinoembryonic actigen (CEA) in the presence of divalent cation in vitro. This protein has a molecular weight of about 21 kD as determined by SDS-polyacrylamide gel electrophoresis, is glycosylated, and includes the amino acid sequence set forth in the Sequence Listing as SEQ ID NO: 2. Also disclosed are antibodies that recognize the CEA binding protein, methods of detecting carcinoma, methods of treating carcinoma, and a kit for screening a patient for carcinoma.

Binding protein for CEA and uses thereof

Disclosed are methods of isolating a protein which binds carcinoembryonic antigen. These methods include the following steps. A biological sample containing carcinoembryonic antigen (CEA) and a CEA-binding protein (CBP) is provided and contacted with a divalent cation at a concentration and for a time sufficient to allow the binding of the CBP to CEA, thereby forming a CBP-CEA conjugate. The sample is then contacted with an adsorbent that binds CEA for a time sufficient to allow adsorbance to the adsorbent. Portions of the sample not adsorbed are removed. The CBP is then disassociated from the conjugate and is collected.

Method for isolating CEA-binding protein

Disclosed is carcinoma orosomucoid-related antigen (CORA), a glycoprotein which has a binding affinity for carcinoembryonic antigen (CEA). This glycoprotein is a marker for carcinoma, and is characterized by having a molecular weight of about 46,000-50,000 daltons on SDS-polyacrylamide gels, an isoelectric point of about 3.0-3.5, a carbohydrate content of about 25-35% by weight, an amino acid sequence defined in the Sequence Listing by SEQ ID NO:1, reactivity with antisera raised thereto, and substantially no reactivity with antisera raised to nonspecific cross-reacting antigen (NCA) or to CEA. Also disclosed is a method for detecting and monitoring carcinoma.

Carcinoma orosomucoid-related antigen, a monoclonal antibody thereto,

Disclosed is a glycoprotein, CORA, which has a binding affinity for carcinoembryonic antigen (CEA). This glycoprotein is a marker for carcinoma, and can be characterized by having a molecular weight of about 46,000-50,000 daltons, an isoelectric point of about 3.0-3.5, a carbohydrate content of about 25-35% by weight, reactivity with antisera raised thereto, and substantially no reactivity with antisera raised to nonspecific cross-reacting antigen (NCA) or to CEA. Also disclosed are a hybridoma which produces a monoclonal antibody to CORA, the monoclonal antibody to CORA, and a device, kit, and method for detecting and monitoring carcinoma.
