Note: The complete
sequence may include tag sequence, target protein sequence, linker sequence and extra sequence that is
translated with the protein sequence for the purpose(s) of secretion, stability, solubility, etc.
If the exact amino acid sequence of this recombinant protein is critical to your application,
please explicitly request the full and complete sequence of this protein before ordering.
Protein Length
Full Length of Mature Protein
Tag Info
C-terminal 10xHis-tagged (This tag can be tested only under denaturing conditions)
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
Buffer
Lyophilized from a 0.2 μm filtered PBS, 6% Trehalose, pH 7.4
Storage
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Lead Time
Basically, we can dispatch the products out in 3-7 working days after receiving your orders. Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Shelf Life
The shelf life is related to many factors, storage state, storage temperature and the stability of the product itself. Generally, the shelf life of lyophilized form is 6 months at -20°C/-80°C from the date of receipt.

Activity
Measured by its binding ability in a functional ELISA. Immobilized PROM1 at 5 μg/mL can bind Anti-PROM1 recombinant antibody (CSB-RA018751MA1HU), the EC50 is 0.4322-0.7189 ng/mL.
Description
CD133 (Prominin-1) is a pentaspan transmembrane glycoprotein widely used as a surface marker for isolating cancer stem cells and hematopoietic progenitors, yet its five-transmembrane topology makes soluble recombinant production notoriously difficult. This construct presents the full-length mature protein (aa 20–865) in a virus-like particle (VLP) format expressed in mammalian cells, preserving native conformation and post-translational modifications critical for antibody recognition. Functional ELISA confirms robust binding activity: immobilized at 5 µg/mL, the protein binds an anti-PROM1 recombinant antibody with an EC50 of 0.43–0.72 ng/mL, supporting use as a positive control in antibody screening, specificity validation, and sandwich ELISA development. Endotoxin levels below 1.0 EU/µg, determined by LAL assay, satisfy criteria typical for cell-based binding studies and flow cytometry antibody titration experiments where lipopolysaccharide interference must be minimized.
