List Biological Laboratories Inc Diphtheria Toxin CRM197 Mutant, Native, 0.25 mg
Since 1978, List Labs products are unsurpassed in quality, consistency, and reliability for the success of your research and development project! Cross reacting material (CRM197) is a nontoxic variant of diphtheria toxin with a single mutation (resulting in a Glycine to Glutamate substitution at postion 52). CRM functions as a carrier protein for polysaccharides and haptens making them immunogenic. CRM is widely used in polysaccharde conjugate vaccines. CRM197 has the advantage of being a well defined protein in contrast to formaldehyde treated toxin (toxoid) which is non-specifically cross linked and subject to rearrangement and loss of epitopes. List Labs CRM197 is purified from the native mutant strain maintaining structural and immunological integrity.
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.

NC1310068 TETANUS TOXOID 100 MICROGRAMS
List Biological Laboratories Inc Tetanus Toxoid from Clostridium tetani, 100 μg
Since 1978, List Labs products are unsurpassed in quality, consistency, and reliability for the success of your research and development project! Tetanus toxin is a potent neurotoxin (150,000 Da) produced by the anaerobic bacterium Clostridium tetani. Intact toxin derived from culture supernatants consists of two polypeptide chains connected through an interchain disulfide bond. List Labs offers the native tetanus toxin produced from Clostridium tetani. Tetanus toxoid is prepared by formaldehyde inactivation of pure neurotoxin. Each lot is verified to be non-toxic. In addition to being a potent antigen, tetanus toxoid is a useful carrier protein for making polysaccharides and haptens immunogenic.

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]

Enzo Life Sciences Toxin A (Clostridium difficile) (100µg)
Has potent cytotoxic and enterotoxic properties. Translocates to the cytosol of target cells and glucosylates small GTP-binding proteins such as Rho, Rac, and Cdc42. Induces actin condensation, cell death and opening of the tight junctions. Triggers release of pro-inflammatory cytokines from intestinal epithelial cells probably via activation of MAP kinases.
