Product Information

Bioactivity

Bioactivity	Measured by its ability to inhibit papain cleavage of a fluorogenic peptide substrate Z-FR-AMC. The IC50 value is < 7 nM.
Description	Kininogen 1 Protein, Human, Recombinant (His) is expressed in HEK293 mammalian cells with His tag. The predicted molecular weight is 71.3 kDa and the accession number is P01042-1.
Species	Human
Expression System	HEK293 Cells
Tag	C-His
Accession Number	P01042-1
Construction	A DNA sequence encoding the human KNG1 isoform 1 (NP_001095886.1) (Gln 19-Ser 644) was fused with a polyhistidine tag at the C-terminus, and a signal peptide at the N-terminus. Predicted N terminal: Gln 19
Protein Purity	> 85 % as determined by SDS-PAGE
Endotoxin	< 1.0 EU/μg of the protein as determined by the LAL method.
Formulation	Lyophilized from a solution filtered through a 0.22 μm filter, containing 25 mM Tris, 100 mM NaCl, pH 7.5. Typically, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization.
Reconstitution	Reconstituted with sterile deionized water to 0.25 mg/mL. Reconstitution conditions may vary depending on the lot.
Synonyms	KNG, kininogen 1, BK, BDK
Research Background	Kininogen-1, also known as high molecular weight kininogen, Williams-Fitzgerald-Flaujeac factor, Alpha-2-thiol proteinase inhibitor, Fitzgerald factor, KNG1, and BDK, is a secreted protein that contains three cystatin domains. Kininogen-1 / KNG1 is a protein from the blood coagulation system as well as the kinin-kallikrein system. It is a protein that adsorbs to the surface of biomaterials that come in contact with blood. Kininogen-1 / KNG1 circulates throughout the blood and quickly adsorbs to the material surfaces. Kininogen-1 / KNG1 is one of the early participants of the intrinsic pathway of coagulation, together with Factor XII (Hageman factor) and prekallikrein. Kininogen-1 / KNG1 is one of the kininogens, a class of proteins. As with many other coagulation proteins, the protein was initially named after the patients in whom deficiency was first observed. When the clinical data were combined, it turned out that all patients had a deficiency of the same protein. Defects in KNG1 are the cause of high molecular weight kininogen deficiency (HMWK deficiency) which is an autosomal recessive coagulation defect. Patients with HWMK deficiency do not have a hemorrhagic tendency, but they exhibit abnormal surface-mediated activation of fibrinolysis.

Storage & Solubility Information

Shipping	In general, lyophilized powders are shipped with blue ice, while solutions are shipped with dry ice.
Storage	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
