Recombinant Mouse HP protein (His tag)

Product Specifications

Background

Haptoglobin is a 406 aminoacids (aa) protein that in humans is encoded by the HP gene. This gene encodes a preproprotein that is processed into alpha (aa 19-160) and beta (aa 162-406) chains that combine as a tetramer to produce haptoglobin. Haptoglobin captures, and combines with free plasma hemoglobin to allow hepatic recycling of heme iron and to prevent kidney damage.
