GUCA2B Human
Prouroguanylin Human Recombinant
Catalog No. HOR-245

Synonyms:
Guanylate cyclase activator 2B, UGN, GCAP-II, GUCA2B.

Introduction:
Prouroguanylin is a 112-amino-acid prohormone precursor of uroguanylin- mature biologically active 16-amino-acid peptide cleaved from its C-terminus. Guanylin binds to receptor-guanylate cyclases (CG-C) resulting in increased intracellular cGMP levels leading to CFTCR (Cystic Fibrosis Transmembrane Conductance Regulator) activation and subsequent rise in fluid and electrolyte secretion into the lumen.
Prouroguanyline knock-out mice showed impaired renal excretion of external NaCl leading to elevated blood pressure independent of the level of diatary salt intake.
Prouroguanylin is the predominant circulating molecular form found in circulation and in biological fluids.

Description:
Prouroguanylin Human Recombinant is 10 kDa protein containing 88 amino acid residues of the human prouroguanylin and 2 additional amino acid residues.

The Prouroguanylin is purified by proprietary chromatographic techniques.

Source:
Escherichia Coli.

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

Formulation:
Sterile filtered and lyophilized from 0.5 mg/ml in 50mM Phosphate buffer pH-7.4.

Specificity:
The recombinant sequence is 100% homologous to the native human sequence.

Purification Method:
Three-step procedure using IMAC and size exclusion chromatography before and after refolding.

Solubility:
Add 0.2 ml of deionized H2O and let the lyophilized pellet dissolve completely.

Stability:
Store lyophilized protein at -20°C. Aliquot the product after reconstitution to avoid repeated thaw-freeze cycles and store at
-80°C. Reconstituted protein can be stored at 4°C for a limited period of time.
The lyophilized protein remains stable until the expiry date when stored at -20°C.

Purity:
Greater than 95.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

Applications:
Western blotting, ELISA

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.
