Human Parathyroid Hormone (7-34), (Recombinant)

Desmopressin

Source:

Description: Desmopressin also called ADH (Anti-Diuretic Hormone) has a molecular formula of C46H64N14O12S2 , Mpr-Tyr-Phe-Gln-Asn-Cys-Pro-D-Arg-Gly-NH2 having a Mw of 1069.23 is the first vasopressin analog with a very high and very specific antidiuretic effect, has been widely used for different therapeutic purposes and is believed to be partly responsible for the formation of memories learning and memory processes. Desmopressin increases urine concentration and decreases urine production. Desmopressin is used to prevent and control excessive thirst, urination, and dehydration.

Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.

Formulation: The protein (1mg/ml) was lyophilized with no additives.

Solubility: It is recommended to reconstitute the lyophilized Desmopressin in sterile 18MO-cm H2O not less than 100 g/ml, which can then be further diluted to other aqueous solutions.

Stability: Lyophilized DDAVP although stable at room temperature for 3 weeks, should be stored desiccated below -180C. Upon reconstitution Desmopressin 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.

Purity: Greater than 98.0% as determined by: (a) Analysis by RP-HPLC. (b) Anion-exchange FPLC. (c) Analysis by reducing and non-reducing SDS-PAGE Silver Stained gel.

Dimers and aggregates: Less than 1% as determined by silver-stained SDS-PAGE gel analysis.

Endotoxin: Less than 0.1 ng/ g (IEU/ g) of DDAVP.

Protein content: Protein quantitation was carried out by two independent methods: 1. UV spectroscopy at 280 nm . 2. Analysis by RP-HPLC, using a standard solution of DDAVP as a Reference Standard.
