Product Properties Alternative Names IL-6 R beta,IL-6RB,CD130,gp130 Species Human Expression Sequence Glu23-Glu619 Accession P40189-1 Tag C-His Expression System HEK293 Molecular Weight The protein has a predicted MW of 68.94 kDa. Due to glycosylation, the protein migrates to 80-110 kDa based on SDS-PAGE result. Purity > 95% as determined by SDS-PAGE and HPLC. Endotoxin < 1.0 EU per μg by the LAL method. Formulation Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. Appearance Lyophilized Powder Reconstitution Method 1. Centrifuge before opening2. Reconstitute with distilled water (>100 μg/mL)3. Aliquot to avoid freeze-thaw cycles Features High purity, high activity, low endotoxin, high batch-to-batch consistency Storage Lyophilized powder: Store at -25 to -15°C; stable for 1 year upon receipt.
