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