Control Peptide for G1043-01 (antiserum) and G1043-01A or G1043-01A1 (affinity purified) Galanin is a 29 aa C-terminally amidated (30 aa, non-amidated in humans), highly conserved but unique neuroendocrine peptide originally isolated from intestine. The first 14 aa are fully conserved in almost all species. Galanin is found in the brain and the gut. It modulates a variety of physiological processed including cognition/memory, sensory/pain processing, neurotransmitter/hormone secretion, and feeding behavior. Several N-terminally elongated (-7-29 and -9-29) or truncated biologically active forms of galanin have also been isolated. Galanin antagonists are chimeric peptides generated by linking the amino terminal portion of galanin to substance P (galantide, M15), bradykinin (M35), the neurokinin antagonist spantide (C7) or an idealized alpha helical region (M40) (see review in refs 2 by Kask et al 1995). Galanin mediated its biological effects by interacting with high affinity cell surface receptors. Pharmacological studies with several peptide antagonists and antagonists of galanin receptor suggest the existence of multiple receptor subtypes, and three galanin receptors (GAL-R1, GAL-R2, and GAL-R3) have been clone thus far. These receptors belong to the family of G-protein coupled receptor superfamily, characterized by seven transmembrane domains. Applications: Suitable for use in ELISA and Antibody Blocking. Not suitable for use in Western Blot due to low molecular weight. Other applications not tested. Recommended Dilution: ELISA: 50-100ng control peptide/well. Antibody Blocking: 5-10ug per 1ug G1043-01A or G1043-01A1 (affinity purified antibody) or per 1ul G1043-01 (antiserum). Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4C for short-term only. For long-term storage, store at -20C. Aliquots are stable for at least 6 months 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.
