Human CD133 Full Length Protein (VLP)

分子别名(Synonym)

CD133,PROM1,PROML1,Prominin-1,AC133

表达区间及表达系统(Source)

Human CD133 Full Length-VLP (CD3-H52P3) is expressed from human 293 cells (HEK293). It contains AA Gly 20 - His 865 (Accession # O43490-1).

Predicted N-terminus: His

蛋白结构(Molecular Characterization)

The protein has a calculated MW of 97.2 kDa | 56.1 kDa.

Virus-like particles(VLPs) are formed by self-assembly of envelop/capsid proteins from viruses. Membrane Proteins can be constituted in-situ with VLPs produced from HEK293 cell cultures. These VLPs concentrate conformationally intact membrane proteins directly on the cell surface and produce soluble, high-concentration proteins perfect for immunization and antibody screening.

The VLPs provide the display of properly folded membrane proteins in their native cellular membrane in a compact size of 100~300 nm diameter (similar to the size of most viruses) making it optimal targets for dendritic cells in vivo and surface attachment for phage display.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

制剂(Formulation)

The VLPs are highly immunogenic, so the immunization strategy should be optimized (antigen dose, regimen and adjuvant).

Supplied as 0.2 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

活性(Bioactivity)-ELISA

CD133 ELISA

Immobilized Human CD133 Full Length-VLP (Cat. No. CD3-H52P3) at 1 μg/mL (100 μL/well) can bind Monoclonal Anti-Human CD133 Antibody,Mouse IgG1 with a linear range of 0.2-4 ng/mL (QC tested).

Protocol

 

均一性(Identity)-DLS

CD133 DLS

The mean peak Radius of VLP is 50-75 nm with more than 95% intensity as determined by dynamic light scattering (DLS).

 

背景(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.
