Endomorphin 1 |

Description: Endomorphins are recently discovered endogenous opioid peptides composed of four amino acids: Endomorphin-1 (EM-1) is Tyr-Pro-Trp-Phe-NH2, and Endomorphin-2 (EM-2) is Tyr-Pro-Phe-Phe-NH2. These peptides have a very high affinity and specificity for mu-opioid receptors as it has been reported in many pharmacological studies. EM-1 is distributed in many brain regions, whereas EM-2 is prevalent in brainstem and spinal cord. EM-1 and EM-2 exert their antinociceptive activity by interacting with mu-opioid receptors. EM-1 anf EM-2 bind with mu-opioid receptor with high affinity and selectivity in comparison with binding to opioid delta and kappa receptors. EM-1 and EM-2 tetrapeptides activate G-proteins and inhibit adenylyl cyclase activity when bind to mu-opioid receptors. Applications: Suitable for use in ELISA and Immunohistochemistry. Other applications not tested. Recommended Dilutions: Immunohistochemistry (Immunofluorescence): 15mg/ml Immunohistochemistry (Avidin-Biotin): 5mg/ml Optimal dilutions to be determined by the researcher. Storage and Stability: Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile ddH2O, 0.1% sodium azide. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Reconstituted product is stable for 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. |
