Catalog No.
HOR-280

Description :

Its molecular weight is 1084.23 having an amino acid sequence of Cys-Tyr-Phe-Gln-Asn-Pro-Lys-Arg-NH2 and a molecular formula: C₄₆H₆₅N₁₅O₁₂S₂.

Physical Appearance:

Sterile Filtered White lyophilized (freeze-dried) powder.

Formulation:

The protein was lyophilized with no additives.

Solubility:

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

Stability:

Lyophilized Vasopressin although stable at room temperature for 3 weeks, should be stored desiccated below -18⁰C. Upon reconstitution Vasopressin 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/ug (IEU/ug) of Vasopressin.

Usage:

Prospec's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.
