Beta toxins bind voltage-independently at site-4 of sodium channels (Nav) and shift the voltage of activation toward more negative potentials thereby affecting sodium channel activation and promoting spontaneous and repetitive firing. Strongly affects skeletal muscle channels Nav1.4/SCN4A, poorly affects the neuronal channels Nav1.6/SCN8A and Nav1.2/SCN2A. Induces spastic paralysis of rear limbs, increased salivation, apnea, tachycardia and increased perspiration.
Source:Recombinant protein corresponding to aa21-84 from Tityus zulianus Beta-toxin Tz1, fused to 10X His-Tag at N-terminal and Myc-Tag at C-terminal, expressed in Baculovirus.
Storage and Stability:May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 6 months after receipt at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
