Abstract: An isolated monoclonal antibody or antigen-binding fragment thereof binds to F. tularensis lipopolysaccharide (Ft LPS). The antibody preferably lacks an Fc region or has an impaired Fc-region. The antibody may be formulated into a pharmaceutical composition along with a pharmaceutically acceptable carrier, excipient or diluent. It may be provided in a kit with means for detection of the antibody and instructions for use. A therapeutically effective amount of such an antibody can be used for prophylaxis, treatment or amelioration of Ft infection and for inhibiting Ft uptake by cells in a subject. The antibody can also be used to detect Ft infection. Also disclosed is an isolated nucleic acid molecule encoding the antibody, an expression vector having the isolated nucleic acid molecule, and a host cell transfected with such an expression vector.

Abstract: The invention provides anionic water-soluble tetracyclic and pentacyclic bacteriochlorophyll derivatives (Bchls) containing at least one, preferably two or three, negatively charged groups and/or acidic groups that are converted to negatively charged groups at the physiological pH, preferably Bchls having a group COO<->, COS<->, SO3<->, PO3<2->, COOH, COSH, SO3H, and/or PO3H2 bound through an ester or amide bond to one or more of the positions 17<3>, 13<3>, and 3<2> of the tetracyclic or pentacyclic Bchl molecule, for photodynamic therapy and diagnosis.

Abstract: An isolated monoclonal antibody or any antigen-binding fragment thereof which binds to ricin toxin, an expression vector including the isolated nucleic acid molecule and a host cell transfected with said isolated nucleic acid molecule or with the expression vector, a pharmaceutical composition including as an active ingredient the isolated monoclonal antibody or any antigen-binding fragment thereof, the bispecific molecule or the immunoconjugate and a pharmaceutically acceptable carrier, excipient or diluent, and a method of prophylaxis, treatment or amelioration of ricin toxin poisoning including administering to a subject in need thereof a therapeutically effective amount of the isolated monoclonal antibody or any antigen-binding fragment thereof, the bispecific molecule, the immunoconjugate or the pharmaceutical composition.

Abstract: The invention provides a pharmaceutical composition comprising as an active ingredient a combination of three isolated monoclonal antibodies or any antigen-binding fragment thereof which bind ricin toxin and neutralize its toxic effects, and a pharmaceutically acceptable carrier, excipient or diluent. The invention also provides a method of prophylaxis, treatment or amelioration of ricin toxin poisoning including administering to a subject in need thereof a therapeutically effective amount of the pharmaceutical composition.

Abstract: Fusion polypeptides are provided including modified human Acetylcholinesterase conjugated to the Fc region of an immunoglobulin. Methods of preparing these polypeptide constructs and uses thereof as scavenging agents of organophosphate compounds are described.
