Product Overview
This rabbit polyclonal antibody detects kininogen-1 (gene Kng1) in mouse samples and is validated for IHC and Western blot. The predicted molecular weight is 73.1 kDa, and the supplier reports an observed band at about 73 kDa.
Kininogen-1 (KNG1) is a plasma protein made in the liver and produced as high- and low-molecular-weight forms. High-molecular-weight kininogen acts as a cofactor in the contact pathway of coagulation, and cleavage of kininogens by kallikreins releases bradykinin or kallidin, peptides that dilate blood vessels and increase vascular permeability. Kininogens also inhibit cysteine proteases.

Validated Applications
| IHC (paraffin sections) | 0.5–1 µg/mL (Mouse) |
|---|---|
| Western blot | 0.1–0.5 µg/mL (Mouse) |
Samples with a confirmed band (WB): mouse lung tissue, mouse testis tissue, mouse liver tissue, HEPA cells, NEURO cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): mouse kidney tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Immunogen
Synthetic peptide from the middle region of mouse kininogen 1. It differs from the rat sequence at thirteen residues.
Reactivity Notes
The supplier lists reactivity with mouse. UniProt describes kininogen-1 as a secreted protein. Tissue expression noted by UniProt (mouse): Plasma. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
