Aqueous buffered solution containing BSA and ≤0.09% sodium azide.

Preparation And Storage

The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with FITC under optimum conditions, and unreacted FITC was removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

Product Notices

  1. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
  2. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  3. Please refer to for technical protocols.
  4. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
  5. Source of all serum proteins is from USDA inspected abattoirs located in the United States.

Reacts with an intracellular epitope of the multidrug resistance protein (MRP1). MRP1 is a 190 kDa integral membrane phosphoglycoprotein, member of the ATP-binding cassette transporter proteins, overexpressed in some drug-selected resistant cell lines and has been shown to cause multidrug resistance in transfected cells. Clone QCRL-3 was generated using non-denatured membranes from H69AR, an MRP1-overexpressing, multidrug resistant, drug-selected cell line. Its epitope has been localized to the first nucleotide binding domain of MRP1 between amino acids 617 and 932.3 QCRL-3 does not cross-react with human MDR1 or MDR3 gene products, nor with murine MRP1. It is reported that mAb QCRL-3 inhibits the ATP-dependent transport activity of MRP1 in inside-out membrane vesicles.

Fluorescein (FITC) is part of the BD blue family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 494-nm and an emission maximum (Em Max) at 518-nm. FITC is designed to be excited by the Blue laser (488-nm) and detected using an optical filter centered near 520 nm (e.g., a 530/30-nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
