Bj-xtrlT (recombinant) | Product ID | L8223 |
| Name | Bj-xtrlT (recombinant) |
| Molecular formula | |
| Description |
It is an excitatory anti-insect selective scorpion beta-toxin. Polypeptide of 76-amino acids cross-linked by 4 disulfide bridges. Recombinant toxin produced in Eschirichia coli initialy from Buthotus judaicus scorpion venom. |
| Biological activity | It is toxic exclusively to insects with an effective dose 50% in blowfly larvae (ED50) of 14 ng/100 mg body weight. The equilibrium dissociation constant, Kd, has been determined in binding assays to cockroach neuronal membranes = 0.15 nM (ref. 3). |
