Our broad portfolio consists of multiplex panels that allow you to choose, within the panel, analytes that best meet your needs. On a separate tab you can choose the premixed cytokine format or a single plex kit.
Cell Signaling Kits & MAPmates™
Choose fixed kits that allow you to explore entire pathways or processes. Or design your own kits by choosing single plex MAPmates™, following the provided guidelines.
The following MAPmates™ should not be plexed together:
-MAPmates™ that require a different assay buffer
-Phospho-specific and total MAPmate™ pairs, e.g. total GSK3β and GSK3β (Ser 9)
-PanTyr and site-specific MAPmates™, e.g. Phospho-EGF Receptor and phospho-STAT1 (Tyr701)
-More than 1 phospho-MAPmate™ for a single target (Akt, STAT3)
-GAPDH and β-Tubulin cannot be plexed with kits or MAPmates™ containing panTyr

Description
Overview
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.

Purity
≥95% by SDS-PAGE
Activity
Binding activity is assessed by hemagglutination assay using trisialoganglioside fixed sheep red blood cells.
Solubility
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.
Storage
+2°C to +8°C
Do Not Freeze
Yes
Special Instructions
Following reconstitution, store in the refrigerator (4°C). Aqueous stock solutions are stable for up to 6 months at 4°C under sterile conditions.
