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). Source: Isolated from mouse submaxillary glands. Biological Activity: Stimulates neurite outgrowth in rat PC12 cells Applications: Suitable for use in Cell Culture, ELISA and Western Blot. Other applications not tested. Recommended Dilutions: Optimal dilutions to be determined by the researcher. Storage and Stability: Lyophilized and reconstituted products are stable for 6 months after receipt at -20C. Reconstitute with sterile ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
