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
Recombinant, Bacillus anthracis anthrax protective antigen (nicked) expressed in a specialized strain of B. anthracis. PA63 is the carboxyl-terminal 63-kDa fragment obtained by the proteolytic cleavage of the receptor-bound protective antigen (PA), one of the three proteins that comprise anthrax toxin. Unlike native PA, PA63 oligomerizes to form a ring-shaped heptamer that binds up to three copies of EF and/or LF competitively and with high affinity (Kd ~1 nM). Whereas native PA persists on the cell surface, the heptamer is endocytosed, presumably because oligomerization aggregates anthrax toxin receptor. The endocytosed toxic complexes are trafficked to endosomal compartments where the low pH causes the PA63 heptamer to insert into the membrane and form a water-filled channel.
