Bordetella Pertussis Adenylate Cyclase, Active
Adenylate cyclase is a toxin produced by a gram-negative coccobacillus, Bordetella pertussis. This toxin penetrates into the animal cells and produces cAMP from ATP in the cytoplasm and can be used for functional studies on the cAMP- signaling pathway.
Bordetella Pertussis FHA
Purified FHA from B. pertussis. This product is presented as at least 95% of the intact 220 kDa form, with 5% in the reported breakdown products of 140 kDa and 90 kDa.
Bordetella Pertussis Toxin
Purified native pertussis toxin from Bordetella pertussis, in lyophilised form for ease of shipping, activity tested in a CHO cluster assay.
Bordetella Pertussis Toxin (Frozen)
Purified native pertussis toxin from Bordetella pertussis in liquid form, activity tested in a CHO cell cluster assay.
Bordetella Pertussis Toxin (Glycerol)
Purified native pertussis toxin from Bordetella pertussis, in glycerol buffer for repeated use and freeze/thawing, activity tested in a CHO cell cluster assay.

Diphtheria Toxin, CRM197 Mutant
CRM197 is a genetically detoxified diphtheria toxin. It is expressed as a soluble, correctly folded ~58kDa recombinant protein in the cytoplasm of E. coli and then produced to >99% purity.
Diphtheria Toxoid (Frozen)
Diphtheria toxoid is a formaldehyde-inactivated toxin purified from Corynebacterium diphtheriae strain NCTC 10648. Toxoid is presented frozen in Tris-EDTA disodium salt buffer.
Pasteurella Multocida Toxin, Active
This toxin is derived from a recombinant ToxA with N-terminal 6xHis-tag expressed in E. coli. Manufactured for studies on the GTP trimer bound protein- dependent signaling pathway and as a PMT antigen for immunological assays such as ELISA, western blotting and dot blotting.
Rabbit Anti-Pasteurella Multocida Toxin Antibody
Anti-Pasteurella mulcosida toxin antibody, rabbit polyclonal.
Streptolysin O (Hemolytic Streptococcus), Active
Recombinant Streptolysin O, highly purified from E. coli over-expressing SLO of Group C hemolytic Streptococci. Reagent for membrane pore formation to introduce small-to-macromolecules into living cells.
Tetanus Toxin, Recombinant Heavy Chain Fragment C
Tetanus toxin, heavy chain fragment C is a recombinant protein that is devoid of the toxin’s enzymatic activity but contains the binding site necessary for uptake of the toxin by neurons, and is the most immunogenic part of the toxin. Fragment C contains the powerful T cell epitopes of tetanus toxin without the toxicity.
