产品名称

Cholera Toxin, Vibrio cholerae, Type Inaba 569B, Azide Free, Cholera toxin Inaba 569B, CAS 9012-63-9, has a single A subunit surrounded by five polypeptides chains of the B subunits. The A subunit catalyzes the ADP-ribosylation of the α-subunit of G-proteins.

storage condition

do not freeze

solubility

soluble (Please refer to the vial label for lot-specific reconstitution. Note: cholera toxin tends to breakdown into its A and B subunits when the solution is frozen or with vigorous shaking during reconstitution, resulting in damage to the toxin protein and concomitant loss of biological activity. Swirl bottles gently during reconstitution. Avoid vigorous pipetting of solutions that would lead to foaming. Heating of cholera toxin in excess of 40-50°C results in aggregation and subsequent breakdown into its A and B subunits.)

Disclaimer

Toxicity: Highly Toxic (H)

General description

Useful for studies involving adenylate cyclase, AMP, and related membrane-transport phenomena. Consists of a single A subunit surrounded by five polypeptide chains of the B subunits. The A subunit catalyzes the ADP-ribosylation of the α-subunit of G-proteins, reducing intrinsic GTPase activity and activating the α-subunit. The B subunits are responsible for the attachment of the native toxin on the cell surface..
Useful for tissue culture applications.
