Ricin Protein, Ricinus communis, Recombinant (His)

Ricin is highly toxic to animal cells, and to a lesser extent to plant cells.; Acts as a glycosidase that removes a specific adenine residue from an exposed loop of the 28S rRNA (A4324 in mammals), leading to rRNA breakage. As this loop is involved in elongation factor binding, modified ribosomes are catalytically inactive and unable to support protein synthesis. Can inactivate a few thousand ribosomes per minute, faster than the cell can make new ones. Therefore a single molecule can kill an animal cell.; Binds to beta-D-galactopyranoside moieties on cell surface glycoproteins and glycolipids and facilitates the entry into the cell of the A chain. Also responsible for cell agglutination (Lectin activity).

Formulation	If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
Reconstitution	A hardcopy of COA with reconstitution instructions is sent along with the products. Please refer to it for detailed information.
Stability & Storage	Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Shipping	In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
