Recombinant Human CD34 Protein, C-His-tagged, Biotinylated

Product Description

Cat

IMP-4216

Official Symbol

CD34

Product Overview

Recombinant extracellular domain of human CD34 precursor (NP_001020280.1) (Met1-Thr290) was expressed with a polyhistidine tag at the C-terminus. The purified protein was biotinylated in vitro.

Description

Cluster of Differentiation 34 (CD34) is a member of a family of single-pass transmembrane sialomucin proteins, and may function as a cell-cell adhesion factor. CD34 protein is selectively expressed on hematopoietic progenitor cells and the small vessel endothelium of a variety of tissues. It has been widely used as a stem and progenitor cell marker, and clinical CD34+ stem cell transplantation (CD34+SCT) has been performed for tumor purging. CD34 monoclonal antibodies are widely used to identify and isolate hemopoietic progenitors and to classify acute and chronic leukemias.
