Induced proliferation of TF-1 cells assay for Human NGF-β. Cell proliferation was measured to calculate the ED50, which is as expected less than 5 ng/ml.
Non-reducing (-) and reducing (+) conditions in a 4 - 20% Tris-Glycine gel stained with Coomassie Blue. 1 μg of protein was loaded in each lane. Human NGF-β has a predicted Mw of 27.3 kDa (each monomer is 13.6 kDa).

Description

Nerve Growth Factor β (NGF-β) is a neurotrophic factor that is important for the development and maintenance of sensory and sympathetic neurons. NGF-β signals through the low affinity nerve growth factor receptor (LNGFR) and the tropomyosin receptor kinase A (TrkA) to activate PI3K, Ras, and PLC signaling pathways. NGF-β is also involved in the growth, differentiation, and survival of B lymphocytes. Human, mouse, and rat NGF-β proteins are cross-reactive.

Activity Assay

Human NGF-β is fully biologically active when compared to standard. The activity is determined by the ability to induce TF-1 cells proliferation and it is typically less than 5 ng/ml. This corresponds to an expected specific activity of 2 x 105 units/mg.
