IL-11 Protein, Human, Recombinant (His)

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. IL-11 Protein, Human, Recombinant (His) is expressed in HEK293 mammalian cells with N-His tag. The predicted molecular weight is 20.24 kDa and the accession number is P20809-1.

説明

Species	Human
Expression Host	HEK293 Cells
Tag	N-His
Accession Number	P20809-1
別名	IL-11Oprelvekin, INN: Oprelvekin, interleukin 11, Adipogenesis inhibitory factor, AGIF, Oprelvekin, IL11, Interleukin-11
Construction	Pro22-Leu199
Protein Purity	> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
分子量	20.24 kDa (predicted). Due to glycosylation, the protein migrates to 21-25 kDa based on Tris-Bis PAGE result.

Endotoxin	< 1 EU/μg by the LAL method.
Formulation	Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization.
Reconstitution	Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.
Stability & Storage	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at-80℃. For reconstituted proteinsolutions, the solution can be stored at -20°c to -80'c for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
Shipping	In general, Lyophilized powders are shipping with blue ice.
