Biotinylated Human CD133 Protein, His,Avitag™

  • Synonym
    CD133,PROM1,PROML1,Prominin-1,AC133
  • Source
    Biotinylated Human CD133 Protein, His,Avitag(CD3-H82Q8) is expressed from human 293 cells (HEK293). It contains AA Gly 20 - His 865 (Accession # O43490-1 ).
    Predicted N-terminus: His
  • Molecular Characterization
    CD133 Structure

    This protein carries a polyhistidine tag at the N-terminus, followed by an Avi tag (Avitag™)

    The protein has a calculated MW of 98.9 kDa. The protein migrates as 90-110 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Labeling
    Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
  • Protein Ratio
    Passed as determined by the HABA assay / binding ELISA.
  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >80% as determined by SDS-PAGE.

  • Formulation

    This product is not suitable for cell based experiments due to cytotoxicity of DDM.
    DDM and CHS are INDISPENSABLE to keep membrane protein soluble and active, under no circumastance should you remove DDM and CHS.
    DDM/CHS buffer (DC-11) is sold separately and not included in protein, and please contact us if you need the buffer.
    If glycerol is not compatible to your application, remove glycerol just before immediate experiment, and NEVER store glycerol-free protein solution.

    Supplied as 0.2 μm filtered solution in 50 mM HEPES, 150 mM NaCl, DDM, CHS, pH7.5 with glycerol as protectant.

    Contact us for customized product form or formulation.

  • Shipping

    This product is supplied and shipped as sterile liquid solution with dry ice, please inquire the shipping cost.

  • Storage

    Please avoid repeated freeze-thaw cycles.

    This product is stable after storage at:

    1. The product MUST be stored at -70°C or lower upon receipt;
    2. -70°C for 12 months under sterile conditions.
*The isotype control of empty/mock nanodisc (Cat. No. APO-H51H3) is sold separately and not included in protein, you can follow this link for product information.
SDS-PAGE
CD133 SDS-PAGE

Biotinylated Human CD133 Protein, His,Avitag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 80%.

 CD133 SPR

Monoclonal Anti-Human CD133 Antibody, Human IgG1 immobilized on CM5 Chip can bind Biotinylated Human CD133 Protein, His,Avitag (Cat. No. CD3-H82Q8) with an affinity constant of 22.9 nM as determined in a SPR assay (in presence of DDM and CHS) (Biacore 8K) (Routinely tested).

  • Background
    Prominin-1 is also known as CD133, Antigen AC133, PROM1, PROML1 and MSTP061. Is used as marker for hematopoietic stem and progenitor cells (HSPC) for somatic stem cell isolation. May play a role in cell differentiation, proliferation and apoptosis . Binds cholesterol in cholesterol-containing plasma membrane microdomains and may play a role in the organization of the apical plasma membrane in epithelial cells. During early retinal development acts as a key regulator of disk morphogenesis. Involved in regulation of MAPK and Akt signaling pathways. In neuroblastoma cells suppresses cell differentiation such as neurite outgrowth in a RET-dependent manner.
