IL-21 Protein | Proton-pump inhibitor proton-pump.com

Name :
IL-21 Protein

Description :
Interleukin-21 (IL-21), produced predominantly by CD4 T cells and natural killer T (NKT) cells, is a newly discovered member of the common γ-chain family of cytokines. It has been implicated in many immunological processes and has been linked to autoimmune diseases, allergies and other inflammatory diseases.

Species :
Mouse

Uniprotkb :
E. coli

Tag :
N-His-Avi

Synonyms :
Interleukin-21, IL-21, Za11, CVID11

Construction :
Recombinant Biotinylated Mouse IL-21 Protein is expressed from E.coli with His tag and Avi tag at the N-Terminus. It contains His18-Ser146.[Accession |Q9ES17]

Protein Purity :
> 95% as determined by Tris-Bis PAGE

Molecular Weight :
The protein has a predicted MW of 17.9 kDa same as Tris-Bis PAGE result.

Endotoxin :
Less than 1EU per μg by the LAL method.

Formulatione :
Supplied as 0.22μm filtered solution in 20mM NaAc, 150mM NaCl (pH 5.5).

Reconstitution :

Stability & Storage :
Valid for 12 months from date of receipt when stored at -80°C. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

Shipping :
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
