List Biological Laboratories Inc Cholera Toxin (AZIDE-FREE) from Vibrio cholerae, 1 mg
Since 1978, List Labs products are unsurpassed in quality, consistency, and reliability for the success of your research and development project! Cholera toxin is an oligomeric protein of MW 84,000 daltons which consists of a single A subunit surrounded by five B subunits. It is a potent activator of adenylate cyclase and is the pathogenic agent responsible for the symptoms of cholera. Cholera toxin has become a powerful research tool not only in microbiology, but in the fields of physiology, cell biology and biochemistry, as well. Because of the effect on adenylate cyclase, cholera toxin is frequently used for the study of signal transduction mechanisms. In addition, cholera toxin acts as an adjuvant through the stimulation of B-lymphocytes. Cholera toxin is isolated from Vibrio cholerae type Inaba 569B and purified from endotoxin.

List Biological Laboratories Inc Pertussis Toxin from B. pertussis, 50 μg Lyophilized in Buffer
Since 1978, List Labs products are unsurpassed in quality, consistency, and reliability for the success of your research and development projects! Pertussis toxin is produced by Bordetella pertussis, the bacterium responisble for whooping cough. Pertussis toxin is a multi-component protein composed of six non-covalently bound subunits ranging in molecular weight from approximately 9 to 28 kDa. . Pertussis toxin has been referred to in literature as lymphocytosis-promoting factor, islet-activating protein, histamine-sensitizing factor, hemagglutinin and pertussigen. The toxin is useful in creating animal models of autoimmunedisease. For example, pertussis toxin is administered to mice along with myelin antigen to create a mouse model of multiple sclerosis, experimental autoimmune encephalomyelitis (EAE).Pertussis toxin is isolated from Bordetella pertussis strain 165, is highly purified and contains all five subunits. This product is offered as a lyophilized powder.
Biotium Tetrodotoxin, With Citrate, 1 mg
Tetrodotoxin (TTX) reversibly blocks excitable sodium channels and has been a widely used tool for studies of excitable membranes of nerve, skeletal muscle and cardiac muscle cells. Biotium offers high quality tetrodotoxin with or without citrate, at a competitive price. Tetrodotoxin, citrate-free can be dissolved in slightly acidic buffer. Tetrodotoxin, with citrate can be dissolved in water to obtain TTX in pH 4.8 citrate buffer.Properties: C11H17N3O8; MW: 319.28; [4368-28-9]

List Biological Laboratories Inc Anthrax Lethal Factor (LF-A), Recombinant from B. anthracis Native Sequence
Since 1978, List Labs products are unsurpassed in quality, consistency, and reliability for the success of your research and development projects! Three proteins are collectively known as anthrax toxin: protective antigen (PA, 83 kDa), lethal factor (LF, 90 kDa) and edema factor (EF, 89 kDa). These proteins play a key role in the pathogenesis of anthrax. EF and LF have enzymatic functions but require PA to achieve their biological effects. The amino terminal ends of EF and LF bind to PA and are responsible for translocation through the pore formed by the PA heptamer. The LF is a zinc dependent metalloprotease which cleaves a specific bond in signaling proteins of the MAP kinase family destroying their ability to signal. MAP kinase pathways are involved in transduction of a variety of signals including those involved in cell proliferation and differentiation. LF is produced recombinantly in the native host and has the native alanine N-terminal preferred for most research..
