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

pET Expression System 42
The pET-41a-c(+) and pET-42a-c(+) vectors incorporate the schistosomal glutathione-S-transferase (GST; GST•Tag) coding sequence as a fusion partner. The GST•Tag sequence has been reported to enhance the production and in some cases the solubility of its fusion partners (Smith 1998). When expressed in a soluble, properly folded form, GST•Tag fusion proteins can be purified with immobilized
glutathione. Gentle elution is achieved with buffers containing reduced glutathione.
Quantification of soluble GST fusions is also possible by assaying the transferase
activity. The pET-41 and -42 series feature the powerful T7lac promoter, and encode the GST•Tag (220 aa) sequence, proteolytic sites, His•Tag (6 aa) sequence, and S•Tag (15 aa) sequence.
In contrast to other commercially
available GST-fusion vectors, the Xa (IleGluGlyArg, pET-42 series) and enterokinase
(AspAspAspAspLys, pET-41 series) proteolytic cleavage sites have been engineered to allow removal of 100% of the vector-encoded sequences and the generation of native
proteins with their authentic N-terminal residues. Unfused proteins can be produced by
using the Nde I cloning site. A version of pET-41 is available as a linearized vector prepared for ligation-independent cloning (LIC) of PCR products.
Another pET vector with the GST•Tag sequence is pET-49b(+). Please see the website description for more information. The His•Tag and S•Tag
sequences enable alternative protein detection and purification procedures to be performed. For example, when enhancing purity with a separate purification method, or when purifying under denaturing conditions.
