In a normal fasting individual, Lp(a) concentrations range from 20-760 mg/L. Lp(a) levels are associated with premature atherosclerosis; thus elevated Lp(a) is considered a high risk factor for coronary heart disease.

Purity: Essentially free of other plasma lipoproteins as determined by electrophoresis using a SPIFE Vis Cholesterol gel kit for lipids and Coomassie Blue for proteins. Greater than 95% of total lipoprotein content by electrophoresis.

Prepared from fresh, non-frozen plasma shown to be non reactive for HBsAg, anti-HCV, anti-HBc, and negative for anti-HIV 1 & 2 by FDA-required tests.

In normal plasma LRG1 has a concentration of 21-50 ug/ml. It is an acute phase protein with levels elevated in patients with bacterial infections; interestingly, during the inflammatory response, LRG1 levels are not correlated with CRP levels.

LRG1 binds cytochrome c, an initiator/amplifier of programmed cell death (apoptosis), and by binding cytochrome c, is thought to play a role in cell survival.

LRG1 is a biomarker associated with several cancers, including non-small cell lung cancer, colorectal cancer, and pancreatic cancer. Recent studies have shown it is three-fold more abundant in ovarian cancer serum compared to non-cancer control serum. LRG1 levels are only moderately correlated with CA125 levels.

Elevated levels of LRG1 in cerebral spinal fluid are being studied as markers for the early diagnosis of Parkinson's disease and progressive supranuclear palsy.

Lyophilized from 10 mM Na acetate, pH 5.5, with 200 mM NaCl.

Low Molecular Weight Kininogen is involved in blood pressure regulation since it is an endogenous protein substrate for tissue kallikrein. Proteolytic cleavage by kallikrein releases vasoactive bradykinin from LMW kininogen. In addition, LMW kininogen, like HMW kininogen, is a major extracellular cysteine protease inhibitor.

High Molecular Weight kininogen, synthesized by hepatocytes, is a multifunctional protein. It is the precursor protein of bradykinin. In addition it is a cofactor in the activation of factor XI, XII, and prekallikrein and a major extra-cellular cysteine proteinase inhibitor. Kininogens inhibit systemic proteases which are thought to have a part in various diseases such as cancer, muscular dystrophy and joint disease.
