DESCRIPTION

• Tag: Native
• Purity: > 92 % as determined by SDS-PAGE
• Source: E. coli
• Species: Rat
• Storage: Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Activity: 1. Immobilized rat CNTF (Cat: 80012-RNAE) at 10 μg/ml (100 μl/well) can bind biotinylated rat CNTFR-His (aa 1-346) (Cat: 80019-R08B) with a linear range of 1.56-50.0 ng/ml. 2. Measured in a cell proliferation assay using TF-1 human erythroleukemic cells. The ED50 for this effect is typically 10-100 ng/ml.
