Buy Purified Native Human Haptoglobin Phenotype 1-1 direct from manufacturer.
MW: Hp 1-1: 86,000
Extinction Coefficient: 1.20
Salt-free lyophilized solid.
Storage: -20°C
Of the three haptoglobin phenotypes, Hp 1-1 is the most effective in binding free hemoglobin and in suppressing the inflammatory responses associated with free hemoglobin. Hp 1-1 protects against vascular complications in diabetes, is associated with sickle cell anemia, and is more common than other phenotypes in cases of cirrhosis.
Individuals who are phenotype 1-1 have the highest concentration of haptoglobin in plasma.
Purity: >=95% by SDS-PAGE, no visible alpha-2 light chain by SDS-PAGE
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.
