Product Description |
Recombinant Human CD34 Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Ser32-Thr290. |
Product Background |
CD34 is a transmembrane phosphoglycoprotein, first identified on hematopoietic stem and progenitor cells. Clinically, it is associated with the selection and enrichment of hematopoietic stem cells for bone marrow transplants. Due to these historical and clinical associations, CD34 expression is almost ubiquitously related to hematopoietic cells, and it is a common misconception that CD34-positive (CD34()) cells in nonhematopoietic samples represent hematopoietic contamination. |

CD34 |
Synonyms |
CD34; RP11-328D5.2; CD34 molecule; HPCA1 |
Accession |
|
Species |
Human |
Biotinylated |
no |
Amino Acid Range |
Ser32-Thr290 |
Molecular Weight |
The protein has a predicted MW of 28.6 kDa. Due to glycosylation, the protein migrates to 90-130 kDa based on Bis-Tris PAGE result. |

Formulation |
Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
Reconstitution |
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water. |
Stability And Storage |
Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles. |
