          Description
          OverviewProvides means to quickly and simply label antibodies or other proteins with fluorescein. Direct labeling of the primary antibody eliminates the need for a secondary antibody, and results in a lower background and overall higher signal-to-noise ratio. Each kit is sufficient to perform at least five conjugations on proteins of 100 µg to 2.5 mg each.

          Product Usage Statements
          Intended useThe Calbiochem® FITC Labeling Kit provides a means of quickly and simply labeling antibodies or other proteins with fluorescein. FITC-antibody conjugates are useful in many applications, such as flow cytometry and immunocytochemistry. Other proteins such as steroids may also be labeled with FITC. Direct labeling of the primary antibody eliminates the need for a secondary antibody, and therefore results in a lower background and an overall higher signal to noise ratio.

          Intended useThe Calbiochem® FITC Labeling Kit provides a means of quickly and simply labeling antibodies or other proteins with fluorescein. FITC-antibody conjugates are useful in many applications, such as flow cytometry and immunocytochemistry. Other proteins such as steroids may also be labeled with FITC. Direct labeling of the primary antibody eliminates the need for a secondary antibody, and therefore results in a lower background and an overall higher signal to noise ratio.
          Materials providedThis kit contains sufficient reagents to perform 5 conjugations of proteins with 0.1-2.5 mg each.

          • FITC (kit Component No. KP4801): 5 vials 0.85 mg each
          • Solvent Reagent (kit Component No. KP4802): 1 vial, 5.0 ml
          • Carbonate Buffer Concentrate (100X) (kit Component No. KP4803): 1 bottle, 100 ml
          • PBS Buffer Conc. (10X; with 1% sodium azide) (kit Component No. KP4804): 1 bottle, 100 ml
          PreparationAntibody/Protein Preparation: Add 10 ml of carbonate buffer concentrate to 990 ml of distilled water and dialyze antibody in buffer overnight.
          Detailed protocol1. Remove the antibody or other protein from dialysis and dilute or concentrate to a final concentration of 2 mg/ml. Place in container suitable for vortexing.
          2. Add 850 µl of Solvent Reagent to one vial of FITC. Mix thoroughly. The FITC should now be at a concentration of 1 mg/ml.
          3. If the protein being conjugated is not IgG, reserve a sufficient amount of the protein so that a 1 mg/ml solution can be measured in a cuvette of 1.0 cm path length in order to calculate the approximate concentration of the final conjugate (see step 3 of Determining the FITC/Protein Molar Ratio). This reserved protein will be used to calculate E0.1%.
          4. For 2.5 mg of antibody or other protein, pipette 500 µl of FITC mixture into the antibody solution and vortex immediately. This provides a conjugation ratio of 200 µg FITC to 1 mg antibody/protein. Mix end-over-end for 2 hours at room temperature, or transfer to a flask and mix with a stir bar and magnetic stirrer. If possible, seal container with aluminum foil while stirring to block out ambient light.
          5. Dilute PBS buffer concentrate 1:10 in distilled water (final azide concentration is 0.1%) for dialysis. Reserve sufficient diluted PBS buffer to prepare a spectrophotometric blank for determining the FITC to protein molar ratio. Transfer the conjugate to dialysis tubing and dialyze overnight at room temperature in the diluted PBS.
          6. Remove from dialysis tubing. Keep refrigerated (short term) or frozen (long term) and protect from light.
          Calculations1. Read the absorbance of the FITC-antibody conjugate at two wavelengths: 280 nm and 495 nm. Use the 1X PBS/0.1%NaN3 as the spectrophotometric blank. Optimal absorbance readings of the conjugated protein will be within the range of 0.2-1.2 ABS. 2. Using the two absorbance readings, calculate the F/P molar ratio of the FITC/Protein conjugate using the following equation:

          Figure 1: F/P Molar Ration

          3. There are 2 equations used for the determination of the concentration of the FITC-antibody conjugate. If the protein used for conjugation was IgG, use the following equation to estimate the concentration of the labeled antibody:

          Figure 2: Concentration of FITC-IgG

          If the protein conjugated was not IgG, use the following equation to estimate the concentration of conjugated protein:

          Figure 3: Concentration of FITC-Protein

          Where E0.1% is the A280 reading of a 1 mg/ml solution of the unconjugated protein, as measured in a cuvette of 1 cm path length.
