Introduction
Human Oxytocin stimulates uterine smooth muscle contractions indirectly and stimulates the mammary glands to increase lactation without increasing the production of milk.
Description
Oxytocin Human Synthetic is a single, non-glycosylated, polypeptide chain containing 9 amino acids and having a molecular mass of 1007.2 Dalton. Oxytocin has a molecular formula of C43H66N12O12S2.
The OT is purified by proprietary chromatographic techniques.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
The Oxytocin was lyophilized from a concentrated (1mg/ml) solution with no additives.
Solubility
It is recommended to reconstitute the lyophilized Oxytocin in sterile 18MΩ-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.
Stability
Lyophilized Oxytocin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Neurophysin 1 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 RP-HPLC.
Amino acid sequence
Cys-Tyr-Ile-Gln-Asn-Cys-Pro-Leu-Gly-NH2.
Specific Activity
1mg of Oxytocin has activity greater than 480IU/mg.
