HPR

SYNONYMS
Haptoglobin-Related Protein, A-259H10.2, Haptoglobin-Related Locus, HP.

INTRODUCTION
Haptoglobin-Related Protein also known as HPR, is a primate-specific plasma protein related with apolipoprotein L-I (apoL-I)-containing high-density lipoprotein (HDL) particles which shown to be a part of the innate immune defense. HPR-bound hemoglobin might contribute to the biologic activity of the circulating apoL-I/Hprcontaining HDL particles. HPR is a clinically significant forecaster of recurrence of breast cancer.

DESCRIPTION
HPR Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 352 amino acids (20-348 a.a) and having a molecular mass of 39.3kDa.HPR is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.

SOURCE
Escherichia Coli.
