Specifications

Deslorelin is a potent LHRH/GnRH agonist has a molecular formula of C64H83N17O12 Pyr-His-Trp-Ser-Tyr-D-Trp-Leu-Arg-Pro-NHEt having a Mw of 1282.47. Deslorelin is being studied in the treatment of cancer as a way to block sex hormones made by the ovaries or testicles. It belongs to the family of drugs called gonadotropin-releasing hormone analogs. It is used for the induction of ovulation in mares. Deslorelin binds to and activates pituitary gonadotropin releasing hormone (GnRH) receptors. Continuous, prolonged administration of goserelin in males results in pituitary GnRH receptor desensitization and inhibition of pituitary secretion of follicle stimulating hormone (FSH) and luteinizing hormone (LH), leading to a significant decline in testosterone production; in females, prolonged administration results in a decrease in estradiol production.
Catalog #	D3220-75
Dimers and Aggregates	Less than 1% as determined by silver-stained SDS-PAGE gel analysis.
Endotoxin	0.1ng/ug (IEU/ug) of Deslorelin.
Protein Content	Protein quantitation was carried out by two independent methods:
	1. UV spectroscopy at 280 nm.
	2. Analysis by RP-HPLC, using a calibrated solution of Atosiban as a Reference Standard.
Solubility	It is recommended to reconstitute the lyophilized Deslorelin in sterile 18M -cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Stability	Lyophilized Deslorelin although stable at room temperature for 3 weeks, should be stored desiccated below -180C. Upon reconstitution Deslorelin should be stored at 40C between 2-7 days and for future use below -180C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please avoid freeze-thaw cycles.
Molecular Weight	1282.47
Purity	98% as determined by RP-HPLC, anion-exchange FPLC and/or reducing and non-reducing SDS-PAGE Silver Stained gel.
Concentration	As reported
Form	Supplied as a lyophilized powder without additives.
Important Note	This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications without the expressed written authorization of United States Biological.
