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
A cell-permeable pyrazone compound that irreversibly (presumably via covalent modification) inhibits ubiquitin-activating enzyme E1 activity (IC50 <10 µM in cell-free E1 ubiquitination reactions), while exhibiting little or no activity against E3, E2, or caspase enzymatic activity. Blocks ubiquitination-dependent protein degradation and other ubiquitination-mediated cellular activities. E1 inactivation by PYR-41 or other means has been shown to result in an overall elevation of sumoylation.
