Human Atosiban

Atosiban is the first oxytocin antagonist to be specifically developed for the treatment of preterm labor. Atosiban has a specific mode of action, inhibiting oxytocin-induced uterine contractions by blocking oxytocin receptors in the uterus. Extensive clinical investigations have shown Atosiban to be at least as effective as current tocolytic agents. In addition, due to its novel and specific mode of action, Atosiban has a markedly improved maternal side effects profile compared with conventional therapies.

Atosiban also called ADH (Anti-Diuretic Hormone) has a molecular formula of C₄₃H₆₇N₁₁O₁₂S₂, 3-Mercaptopropionyl-D-Tyr(ET)-Ile-Thr-Asn-Cys-Pro-Orn-Gly-NH₂ having a Mw of 994.2 Dalton.

Sterile Filtered White lyophilized (freeze-dried) powder.

The Atosiban peptide was lyophilized with no additives.

It is recommended to reconstitute the lyophilized Atosiban in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

Lyophilized Atosiban although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Atosiban 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.

Greater than 98.0% as determined by analysis by RP-HPLC.
