||Mouse NGF (2.5S) was isolated from mouse submaxillary glands by method of Mobley et al (1976) and is a form of beta-NGF that has identical biological properties. NGF is known to regulate the survival and development of certain sympathetic and sensory neurons. It is a dimer with 2 identical polypeptide chains and dimeric molecular weight of approximately 26,500 Da. Isolation and purification of NGF from mouse submaxillary glands yields preparations of NGF (2.5S) with identical biological activity but with cleavages at the amino terminus (with the loss of 8 amino acids) and/or at the carboxy-terminus (with the loss of arginine). These preparations are named 2.5 NGF (see reference below).

||mouse NGF; beta NGF
||The homodimer has a molecular weight of ~26KDa and the monomer ~13KDa as confirmed by SDS PAGE.
||Greater than 90% (as determined by SDS electrophoresis)
||Tested by stimulation of 8 day old chick embryo dorsal root ganglia.
||Lyophilised from PBS, pH 7.4 without preservatives.
||Reconstitute with the addition of 25 µL sterile water and divide into single use aliquots.
||Store lyophilized protein at 2-8C. After reconstitution, store at 2-8C short term. Store long-term at -20C to -80C. Avoid repeated freezing and thawing. See expiration date for shelf-life estimates, actual times may vary depending upon experimental conditions and laboratory handling.
||12 months upon purchase for dry material. Hydrated material, 5 days at 4C, 30 days -20C, 60 days -70C for highest activity Avoid repeated freezing and thawing. Use insulated storage containers for best results.
