Anti-Rattin (humanin-like)

A novel rat gene, Rattin, encodes a peptide homologous to Humanin, a secreted peptide that specifically protects against neuronal cell death induced by beta-amyloid peptide (Ab) or by mutations causing early-onset familial Alzheimer's disease. Rattin is the prototype of a novel class of peptides, phylogenetically related to Humanin, endowed with protective activity not only against Ab but also toward excitotoxic neuronal death. The rat gene, Rattin, encodes a peptide of 38 residues (15 residues longer than Humanin) showing 73% identity in the conserved region to Humanin. Applications: Western Blot: Use at 1:500 dilution. However, the investigator should determine the optimal dilution for a specific application such as immunohistochemistry. Storage and Stability: May be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (40-50%). Store at -20°C or colder. Aliquots are stable for at least 12 months at -20°C. 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.
