Abstract: The invention provides a one-step process for preparing a cell-binding agent cytotoxic agent conjugate comprising contacting a cell-binding agent with a cytotoxic agent to form a first mixture comprising the cell-binding agent and the cytotoxic agent and contacting the first mixture comprising the cell-binding agent and the cytotoxic agent with a bifunctional crosslinking reagent, which provides a linker, in a solution having a pH of about 4 to about 9 to provide a second mixture comprising the cell-binding agent cytotoxic agent conjugate, wherein the cell-binding agent is chemically coupled through the linker to the cytotoxic agent, free cytotoxic agent, and reaction by-products. The second mixture is then optionally subjected to purification to provide a purified cell-binding agent cytotoxic agent conjugate.
Abstract: The present invention relates to the use of an immunotherapeutic agent having cell wall fragments of a virulent strain of Mycobacterium tuberculosis for the preparation of a drug suitable for the primary prophylaxis of tuberculosis. The immunotherapeutic agent is capable of inducing a protective response that is more effective than the conventional BCG vaccine and reduces the number of viable bacilli in the lungs and in the spleen of individuals recently infected by M. tuberculosis.

Abstract: A bivalent vaccine against Scuticociliatosis, Vibriosis and marine ich in zobaidy, sobaity and hamoor includes a formalin killed whole cell Vibrio encapsulated Uronema spp. The vaccine is made by collecting a mass of infected zobaidy and scraping the moribund fish with a plastic spatula to transfer live Uronema into a pretri dish. The cerebro-spinal fluid is removed from the zobaidy and added to the fluid containing the Uronema at different concentrations formed with the BHIB. A mass of zobaidy juvenile are fed a commercial pellet feed coated with formalin inactivated Uronema spp. encapsulated in Vibrio four times a day for a period of ten days.

Abstract: Provided herein is a large immuno-sorbent surface area assay (ALISSA) for the rapid and sensitive detection of botulinum neurotoxins (BoNTs) and anthrax toxin. This assay is designed to capture a low number of toxin molecules and to measure their intrinsic protease activity via conversion of a fluorogenic or luminescent substrate. Also provided herein are novel peptides that can be specifically cleaved by BoNT and novel peptides that are resistant to cleavage by BoNT. The combination of these cleavable and control peptides can be used for implementation of an exemplary ALISSA used to specifically detect BoNT enzymatic activity. Furthermore, the ALISSA as described herein may also be used in a column based format for use in a high-throughput system for testing large quantities of samples.
Abstract: The present invention refers to the recombinant vaccine against canine visceral leishmaniasis containing the recombinant A2 protein and saponin, as an adjuvant, allowing the distinction between vaccinated and infected animals through conventional ELISA or immunofluorescence tests that employ antigens of promastigote forms of Lesihmania.

Abstract: The invention is a method for reducing the symptoms of vertigo. The method is performed by delivering a therapeutically effective amount of presynaptic neurotoxin, such as Botulinum Toxin A, in a pharmaceutically safe form to suitable locations around the head and neck.
Abstract: The present invention provides improved formulations of botulinum toxin that increase delivery of the botulinum toxin to neural and associated tissues and exhibit a higher specific neurotoxicity and higher potency (in LD50 Units) than available formulations of botulinum toxins. These improved formulations enable physicians to treat a wide variety of pathological conditions with a lower toxin load that reduces the risk of inducing an immune response against the toxin and its associated proteins that may ultimately lead to the development of toxin resistance. These benefits are particularly important in the treatment of conditions that require high-dose or chronic administration of botulinum toxin. Additionally, the decreased in LD50 Unit doses of inventive formulations allows for controlled administration limits diffusion. The present invention also provides methods of treating neuromuscular diseases and pain, using low-dose botulinum toxin.
