Synonyms : Interleukin-6; B Cell Hybridoma Growth Factor; Interleukin HP-1 
Host :  CHO cell
Sequence :  The extracellular domain of mouse IL-6 (NP_112445.1)(Met1-Thr211) is fused to the N-terminus of the Fc portion of a mutant mouse IgG2a. 
Molecular Mass :  51KDa
Non-lytic :  Acts as a long lasting fusion protein which only binds to the receptor. Mutations to  the complement(C1q) and FcgRI  binding sites of the IgGs Fc fragment render the fusion proteins incapable of antibody directed cytotoxicity(ADCC) and complement directed cytotoxicity (CDC).
Purity :  ≥98%，by SDS-PAGE under reducing conditions. 
Endotoxin Content :  <0.06 EU/μg as determined by LAL test.

Activity :  Measured by the dose-dependent stimulation of the proliferation of IL-6 dependent mouse 7TD1 cells 
Formulation :  Lyophilized from 0.2μm-filtered solution in PBS.
Reconstitution :  Reconstitute at 100μg/ml in sterile PBS.
Use / Stability :  Stable for at least 1 year after receipt when stored at -20°C. Working aliquots are stable for up to 3 months when stored at -20°C. Avoid freeze/thaw cycles.
