Description

Endomorphin-2 is an endogenous agonist at μ-opioid receptors (μORs) in the spinal cord; it exhibits antinociceptive/analgesic, immunosuppressive, and pro-angiogenic activities. Endomorphin-2 increases pain thresholds in animal models of thermal pain and inhibits the formation of antibodies in other cellular models. In HUVECs, this peptide stimulates proliferation, migration, adhesion, and tube formation.

Custom Order

  • Size of single unit expressed as number (e.g. '500' in the case of 500 mg)
  • Total quantity of unit size desired (e.g. '10' in the case of 10 x 500 mg). If only one unit is desired, you may leave this blank.
  • This field is for validation purposes and should be left unchanged.
