Molecular Weight: 14 kDa

Accession number: P20783

Accession number: P20783

Purity: > 95 % (SDS-PAGE, RP-HPLC)

Form: lyophilised

Solubility: It is recommended to reconstitute the lyophilised NT-3 in sterile bidest H2O not less than 100 μg/ml. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).

Activity: ED50: < 20-50 ng/ml, determined by the dosedependent induction of choline acetyl transferase in rat basal forebrain primary septal culture.

NT-3 is a neurotrophic factor involved in regulating the survival of visceral and proprioceptive sensory neurons. It is closely homologous to Nerve Growth Factor beta (NGF-b) and BDNF. NT-3 is found in neurons of the central nervous system. NT-3 is expressed also in muscles and its expression is downregulated in denervated muscles. Many human gliomas express and secrete NT-3 into the conditioned medium. Recombinant human NT-3 produced in E. coli is a single, non-glycosylated polypeptide chain containing 119 amino acids and having a molecular mass of 13.6 kDa. Recombinant human NT-3 is purified by proprietary chromatographic techniques.

Endotoxin: Less than 0.1 ng/μg (IEU/μg) of NT-3.
