Rat CNTF / Ciliary Neurotrophic Factor Protein

Species : Rat

Synonyms :

Host : E. coli

Purity :> 92 % as determined by SDS-PAGE

Activity : 1. Measured by its binding ability in a functional ELISA. Immobilized rat CNTF (Cat: 80012-RNAE) at 10 £gg/ml (100 £gl/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 30-120 ng/ml.
