Name : Cynomolgus IL-11 Protein
Product Source :
Recombinant Cynomolgus IL-11 Protein is expressed from HEK293 with His tag at the N-Terminus. It contains Pro22-Leu199.[Accession | P20808]
Molecular Weight :
The protein has a predicted MW of 20.48 kDa. Due to glycosylation, the protein migrates to 21-25 kDa based on Tris-Bis PAGE result.
Endotoxin Level :
Less than 1EU per μg by the LAL method.
Purity :
> 95% as determined by Tris-Bis PAGE> 95% as determined by HPLC
Formulation :
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution :
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
Storage and Stability :
-20 to -80°C for 12 months as supplied from date of receipt.-80°C for 3-6 months after reconstitution.2-8°C for 2-7 days after reconstitution.Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Product Concentration :
Tris-Bis PAGE Cynomolgus IL-11 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Cynomolgus IL-11 is greater than 95% as determined by SEC-HPLC. SPR Data Human IL-11 R alpha, hFc Tag captured on CM5 Chip via Protein A can bind Cynomolgus IL-11, His Tag with an affinity constant of 0.25 nM as determined in SPR assay (Biacore T200).
Background :
Abstract Interleukin-11 (IL-11) is a pleiotropic cytokine that belongs to gp130 family. IL-11 and its receptor, IL-11Ra, are expressed in human cancers,human cancer cells expressed a functional IL-11Ra subunit, which triggered signal transduction either by exogenous recombinant human IL-11 or by autocrine production of IL-11 in cells cultured under hypoxic conditions.
Synonyms :
