General description

Albumin makes up 60% of the plasma protein,[1] which is produced by the liver.[2] It regulates colloid osmotic pressure. Albumin is implicated in the transportation, distribution and metabolism of fatty acids, thyroid hormones and drugs.[2] It reduces weight gain, blocks pulmonary edema, decreases ascites and lowers tissue edema.[3]

Application

Albumin−fluorescein isothiocyanate conjugate has been used:
  • as a control to compare the intracellular delivery efficiency of proteins with or without carrier[4]
  • for the fluorescent visualization of proteins and cells[5][6]
  • as a blocking agent in ELISA[7]
  • as a chemical for brain perfusion and fixation[8]
  • for in vivo capillary–epithelial permeability experiment[9]
  • for confocal microscopy of right ventricular (RV) vasculature in rats[10]

Preparation Note

Prepared from crystallized and lyophilized albumin (A 4378).

      Helpful?

  2. Is the conjugate chromophore based 5-fluorescein, 6-fluorescein, or is based on an isomeric (5/6-) mixture?

    1 answer
    1. The chromaphore used to prepare this product is Fluorescein 5-isothiocyanate.

      Helpful?

  3. Is there any free FITC present in Product A9771, Albumin-fluorescein isothiocyanate conjugate?

    1 answer
    1. We would not expect there to be free FITC. The final product is dialyzed against distilled water using dialysis tubing with a molecular weight cutoff of 12,000 prior to it being lyophilized.
