AU040960

• 100ug (NPP1166) Please inquiry

Catalog Number	P50589-M08H
Organism Species	Mouse
Host	Human Cells
Synonyms	AU040960
Molecular Weight	The recombinant mouse CD34 consists of 264 amino acids and has a predicted molecular mass of 28.6 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rmCD34 is approximately 50-60 kDa due to glycosylation.
predicted N	Thr 35
SDS-PAGE
Purity	> 98 % as determined by SDS-PAGE
Protein Construction	A DNA sequence encoding the extracellular domain of mouse CD34 (NP_001104529.1) (Met 1-Thr 287) was expressed, with a polyhistidine tag at the C-terminus.
Bio-activity	Measured by the ability of the immobilized protein to support the adhesion of the HUVEC human umbilical vein endothelial cell line . When 4 x 10E4 cells/well are added to mouse CD34 coated plates (0.8 μg/ml, 100 μl/well), approximately >30 % will adhere after one hour at 37 ℃.
Research Area	Developmental Biology |Embryogenesis |Germ Layer Formation |Mesoderm
Formulation	Lyophilized from sterile PBS, pH 7.4 1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
Background	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.
