Recombinant Human CD34 (C-His)

Recombinant Human CD34 (C-His)(C00U)

 

产品说明(Description)

Recombinant Human Hematopoietic progenitor cell antigen CD34 is produced by our Mammalian expression system and the target gene encoding Ser32-Thr290 is expressed with a 6His tag at the C-terminus.

Accession #: P28906

Known as: Hematopoietic progenitor cell antigen CD34; CD34

 

制剂(Formulation)

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

 

质量控制(Quality Control) 

Purity:            Greater than 95% as determined by reducing SDS-PAGE.    

Endotoxin:    Less than 0.1 ng/ug (1 EU/ug) as determined by LAL test.

 

复溶(Reconstitution)

Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
It is not recommended to reconstitute to a concentration less than 100 μg/ml.
Dissolve the lyophilized protein in distilled water.
Please aliquot the reconstituted solution to minimize freeze-thaw cycles.    

 

保存(Storage)

Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7°C for 2-7 days.Aliquots of reconstituted samples are stable at < -20°C for 3 months.     

 

背景(Background)

Human CD34 is high glycosylated type I transmembrane protein, and it 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. CD34 is found on multipotent precursors, bone marrow stromal cells, embryonic fibroblasts, vascular endothelia, as well as some populations of mesenchymal stem cells, and tumor cell lines, and it is a common marker for diverse progenitors.
