Abstract: The invention relates to the isolation, characterization and expression of DNA fragments encoding sphingomyelinases D from three species of Loxosceles genus spiders, namely L. boneti., L. reclusa and L. laeta, and the toxoids thereof. The invention also relates to the production of active sphingomyelinases D and the toxoids thereof using recombinant means and to the use of same as an immunogen for the production in vertebrates of antibodies that neutralize the corresponding venom and the respective fragments F(ab?)2. The invention further relates to the use of recombinant sphingomyelinases D as part of an antigen matrix which can be used in the immunopurification of antibodies and the fragments thereof or as part of any diagnostic device used to obtain clinical confirmation that the causal agent of poisoning in a patient is a spider of the Loxosceles genus.

Abstract: The present invention is directed to a pharmaceutical composition comprising F(ab?)2 antibody fragments that are preferably free from albumin and of whole antibodies and also substantially free of pyrogens, and an effective amount of a pharmaceutically acceptable carrier. It is also directed to a method for the production of a pharmaceutical composition comprising F(ab?)2 antibody fragments using scrum or blood plasma of a mammal that has been previously immunized as a source of antibodies. The serum or blood plasma is digested with an enzyme pepsin, followed by separation and purification until the pharmaceutical composition of F(ab?)2 fragments is free of albumin and complete antibodies, and substantially free of pyrogens.

Abstract: The present invention provides a plurality of chimeric single chain variable region (scFv) antibodies. The chimeric scFv antibodies individually comprise variable regions from both horse and non-horse antibodies. Methods of making and using the plurality are also provided.

Abstract: The present invention relates to novel thrombolitic v-PA's which dissolve blood clots in the human body and thus are suitable for the treatment of cardial infarction, for example.

Abstract: The invention relates to a natural protein or a protein that can be synthetically produced, which is a thrombin inhibitor and can be isolated from the saliva of insects which suck the blood of mammals. Preferred is the Triatoma pallidipennis insect. The protein is used for the treatment of thromboses or unstable angina or arteriosclerosis, or for the prevention of a reblockage of vessels after PTCA/PTA or for the prevention of blood clotting in hemodialysis.

Abstract: The invention provides a protein which inhibits collagen-induced platelet aggregation, derived from Triatoma pallidipennis, and derivatives thereof. The protein is useful for inhibition of collagen-induced human platelet aggregation or of cancer with metastatic tumor cells.
