Technical Data
CD34 (Endothelial Cell Marker, Cluster Designation 34, Hematopoietic Progenitor Cell Antigen CD34, HPCA1)
CD34 is a 110-120kD type I transmembrane glycoprotein that belongs to the CD34/Podocalyxin family of sialomucins. It is a widely used marker of activated hematopoietic stem/progenitor cells and is also expressed on adult vascular endothelial cells. Mature rat CD34 is predicted to be a 352aa protein with a 257 aa extracellular domain (ECD) (aa35-291) and 74aa cytoplasmic tail (aa313-386). Over the region used as immunogen, rat CD34 shares 83% and 57% aa identity with mouse and human CD34, respectively.

Suitable for use in Immunohistochemistry, Western Blot and Direct ELISA. Other applications not tested.

Recommended Dilutions:
Immunohistochemistry: 5-15ug/ml stains perfusion fixed frozen sections of rat liver.
Western Blot: 0.1ug/ml stains recombinant rat CD34.
Optimal dilutions to be determined by the researcher.

Storage and Stability:
Lyophilized powder may be stored at -20C. Stable for 12 months after receipt at -20C. Reconstitute with sterile PBS. Aliquot to avoid repeated freezing and thawing. Store at -20C. Reconstituted product is stable for 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
