kininogen [ki-nin´o-jen″] either of two plasma α2-globulins that are kinin precursors. High-molecular-weight (HMW) kininogen (also called Fitzgerald factor) is split by plasma kallikrein to produce bradykinin; low-molecular-weight (LMW) kininogen is split by tissue kallikrein to produce kallidin. Deficiency of HMW kallikrein is a rare condition but may be considered when prolonged time" >activated partial thromboplastin time cannot be explained by deficiencies of other more common factors.ki·nin·o·gen (ki-nin'ō-jen'), The globulin precursor of a plasma kinin.ki·nin·o·gen (ki-ninō-jen) The globulin precursor of a (plasma) kinin. |
