Product Name

CD34, Recombinant Protein

Full Product Name

Human CD34 Recombinant

Product Synonym Names
CD34; CD-34
Research Use Only
For Research Use Only. Not for use in diagnostic procedures.
3D Structure
ModBase 3D Structure for P28906
HEk293 Cells
>95%, as determined by SDS-PAGE and HPLC
Recombinant CD34 is supplied as a 0.2 um filtered PBS solution, pH7.2.
Host Note
Optimized DNA sequence encoding Human extracellular domain of human CD34 including a C-terminal 6His tag was expressed in HEK293 cells.
Endotoxin content was assayed using a LAL gel clot method.
Endotoxin level was found to be less than 0.1 ng/ug (1EU/ug).
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
Molecular Weight Note
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.
Preparation and Storage
The lyophilized protein is stable for at least 2 years from date of receipt at -20 degree C.
Upon reconstitution, this cytokine can be stored in working aliquots at 2 degree - 8 degree C for one month, or at -20 degree C for six months, with a carrier protein without detectable loss of activity.

Avoid repeated freeze/thaw cycles.
Other Notes
Small volumes of CD34 recombinant protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
Related Product Information for
CD34 recombinant protein
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

NCBI Summary for CD34
The protein encoded by this gene may play a role in the attachment of stem cells to the bone marrow extracellular matrix or to stromal cells. This single-pass membrane protein is highly glycosylated and phosphorylated by protein kinase C. Two transcript variants encoding different isoforms have been found for this gene.

UniProt Comments for CD34
CD34: Possible adhesion molecule with a role in early hematopoiesis by mediating the attachment of stem cells to the bone marrow extracellular matrix or directly to stromal cells. Could act as a scaffold for the attachment of lineage specific glycans, allowing stem cells to bind to lectins expressed by stromal cells or other marrow components. Presents carbohydrate ligands to selectins. Selectively expressed on hematopoietic progenitor cells and the small vessel endothelium of a variety of tissues. Belongs to the CD34 family. 2 isoforms of the human protein are produced by alternative splicing.
