HumanKine growth factors are expressed in a proprietary human 293 protein expression system and are manufactured without the use of any animal products and are considered Xeno-Free.

Nerve Growth Factor (β-NGF) is a well characterized neurotropic protein that plays a critical role in the development of sympathetic and some sensory neurons in the peripheral nervous system. In addition, NGF can also act in the central nervous system as a trophic factor for basal forebrain cholinergic neurons. NGF has also been shown to have biological effects on nonneuronal tissues. β-NGF is a neurotrophic factor structurally related to BDNF, NT-3 and NT-4. The functional form of human β-NGF is a noncovalently disulfide-linked homodimer, of two 13.5 kDa polypeptide monomers (238 total amino acid residues).

HumanKine beta NGF is manufactured using all non-animal reagents and is considered Xeno-Free

The specific activity was determined by the dose-dependent stimulation of the proliferation of human TF-1 cells (human erythroleukemic indicator cell line). ED50 is typically 1.5-8 ng/ml.

Product is presented in PBS and filtered through a 0.2 micron filter before lyophilization.

Store at -20°C for up to 4 months from date of receipt. Further dilutions should be made into appropriate buffer or medium to which protein has been added.
