Overview
Haptoglobin 2-2 (Hp 2-2) is the least effective of the three haptoglobin phenotypes in binding free hemoglobin and therefore provides less antioxidant benefits than Hp 1-1. Hp 2-2 is associated with renal failure, familial epilepsy, hypertension, atherosclerosis and coronary heart diseases.
Individuals who are phenotype 2-2 have the lowest concentration of haptoglobin in plasma.
Prepared from plasma shown to be non reactive for HBsAg, anti-HCV, anti-HBc, and negative for anti-HIV 1 & 2 by FDA approved tests.

Biochemical and Physiological Mechanisms
As a result of hemolysis, hemoglobin is found to accumulate in the kidney and is secreted in the urine. Haptoglobin captures, and combines with free plasma hemoglobin to allow hepatic recycling of heme iron and to prevent kidney damage. Haptoglobin also a
After centrifugation, we suggest addition of de-ionized H2O to the original volume (See COA), followed by gentle mixing to ensure adequate homogenization.
