Tag : |
His |
Protein Length : |
1-436 aa |
Description : |
Botulinum toxin acts by inhibiting neurotransmitter release. It binds to peripheral neuronal synapses, is internalized and moves by retrograde transport up the axon into the spinal cord where it can move between postsynaptic and presynaptic neurons. It inhibits neurotransmitter release by acting as a zinc endopeptidase that catalyzes the hydrolysis of the '58-Gln-|-Lys-59' bond of synaptobrevins-1 and -2. |

Purity : |
> 90% as determined by SDS-PAGE. |
Notes : |
Repeated freezing and thawing is not recommended. Store working aliquots at 4 centigrade for up to one week. |
Storage : |
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20 centigrade/-80 centigrade. The shelf life of lyophilized form is 12 months at -20 centigrade/-80 centigrade. |
Concentration : |
A hardcopy of COA with reconstitution instruction is sent along with the products. |
