Mouse Kininogen Light Chain Antibody Summary

Species Reactivity

Mouse

Specificity

Detects mouse Kininogen Light Chain in direct ELISAs and Western blots. In Western blots, reacts with full length Kininogen (aa 21‑661) and several forms of the light chain starting at residue 389, and does not react with the heavy chain. In Western blots, no cross-reactivity with recombinant mouse (rm) Cystatin A, B, C, E/M, recombinant human (rh) Cystatin D, F, S, SA, SN, rmCystatin/Stefin Homolog, rmFetuin A, rhFetuin B, rmHPRG, rhKininogen, or rhKininostatin is observed.

Background: Kininogen

Kininogen, also known as alpha 2-thiol proteinase inhibitor, is a multi-function protein. There are two alternatively spliced forms, designated as the high molecular weight (HMW) and low MW (LMW) forms (1). The mouse HMW form is synthesized as a 661 amino acid (aa) precursor with a signal peptide (aa 1‑20). The mature chain (aa 21‑661) is further processed into the heavy (aa 21‑379) and the light (aa 389‑661) chains. The active peptide bradykinin (aa 380‑388) is released which has a variety of functions including muscle contraction, hypotension and inflammation. The heavy chain consists of three cystatin-like domains which are responsible for inhibiting cysteine proteases. The light chain consists of a His‑rich domain which is associated with the clotting activity. In comparison to the HMW form, the LMW Kininogen (432 residues) has the same sequence in its heavy chain and bradykinin but has a different sequence in its light chain (aa 401‑432). The LMW form is not involved in blood clotting.
