Images & Validation

• Tested Applications: DOT
• Application Notes:
  Human Transferrin Biotin has been tested in dot blot and is designed for Immunoblotting, ELISA, immunohistochemistry, immunomicroscopy as well as other antibody based assays using streptavidin or avidin conjugates.

Key Properties

• Source: Human
• Biological Origin: Human
• Isotype: Transferrin
• Conjugation: Biotin
• Purity: This product was prepared from normal serum by a multi-stage process that includes delipidation and selective precipitation. Assay by immunoelectrophoresis resulted in a single precipitin arc against anti-biotin, anti-Human Transferrin and anti-Human Serum.

Ex vivo fluorescence imaging of biodistribution of the nanoparticles in an orthotopic mouse model of PBT. Notes: (A) Fluorescent signal observed in the brains of four separate mice with PBT (1–24 hours) injected intravenously (via tail vein) with transferrin-coated Prussian blue nanoparticles (MnPB-ATxRd-Tf). A control mouse with PBT was not injected with nanoparticles. (B) Representative ex vivo fluorescence imaging of organ biodistribution of the nanoparticles at 3 hours post-injection. (C) Histograms quantifying the observed fluorescence biodistribution of the nanoparticles 3 hours post-injection. ROIs for intensity measurements are indicated by white dashed lines in (B). Abbreviations: PBT, pediatric brain tumor; MnPB, manganese-containing Prussian blue; ATxRd, Texas Red-labeled avidin; Tf, transferrin; ROI, region of interest; au, arbitrary units. Human Transferrin Biotin Conjugated (p/n orb346261).
