Introduction: Alarelin (Gonadotrophin-releasing hormone) is a synthetic LH-RH agonist that is found in higher amounts than that of LH-RH in rat hypophyseal stimulation of gonadotropin secretion in vivo and in vitro and in ovulation inductions. Alarelin is known for its induction of ovulation. Alarelin acetate is the acetate form of a hypothalamic peptide that stimulates the release of FSH and LH from the pituitary gland.Description: Alarelin acetate peptide is a single, non-glycosylated polypeptide chain containing 9 amino acids, having a molecular mass of 1167.3 Dalton and a Molecular formula of C56H78N16O12 x C2H4O2. The CAS No. is 79561-22-1.Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.Formulation: The Alarelin was lyophilized with no additives.Solubility: It is recommended to reconstitute the lyophilized Argipressin in sterile 18MΩ-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.Stability: Lyophilized Alarelin e although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Alarelin should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.Purity: Greater than 99.0% as determined by Analysis by RP-HPLC.
