Optimized DNA sequence encoding Human extracellular domain of human CD34 including a C-terminal 6His tag was expressed in HEK293 cells.

Molecular weight:
Recombinant CD34 is a monomer protein consisting of 270 amino acid residue subunits, due to glycosylation migrates as an approximately 50 kDa protein on SDS-PAGE.

>95%, as determined by SDS-PAGE and HPLC

Biological Activity:
Measured by the ability to support the adhesion of the HUVEC cell line. Coated plates with immobilized recombinant Human CD34 ( 0.8 μg/mL) are able to adhere 40% of cells ( 4 x 104 cells/well) after one hour at 37 ℃

Endotoxin content was assayed using a LAL gel clot method.
Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).

Recombinant CD34 is supplied as a 0.2 μm filtered PBS solution, pH7.2.

A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers

The lyophilized protein is stable for at least 2 years from date of receipt at -20° C.
Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8° C for one month, or at -20° C for six months, with a carrier protein without detectable loss of activity.

Avoid repeated freeze/thaw cycles.

CD34 is a transmembrane glycoprotein expressed by human hematopoietic progenitor cells of lymphoid and myeloid lineage, and various types of colony-forming activity in human bone marrow (BM), cord blood (CB), and mobilized peripheral blood (PB) are contained in the CD34+ population. It has been suggested that CD34 also defines a normally occurring population of dendritic cells within the endoneurium of peripheral nerves that is distinct from fibroblasts and conventional Schwann cells
