  • Product overview

    FITC Conjugation Kit ab102884 uses a simple and quick process to conjugate an antibody to FITC . It can also be used to conjugate other proteins or peptides.

    To conjugate an antibody to FITC using this kit:
    - add modifier to antibody and incubate for 3 hrs
    - add quencher and incubate for 30 mins
    The conjugated antibody can be used immediately in WB, ELISA, IHC etc. No further purification is required and 100% of the antibody is recovered for use.

    Learn about buffer compatibility below; for incompatible buffers and low antibody concentrations, use our rapid antibody purification and concentration kits. Use the FAQ to learn more about the technology, or about conjugating other proteins and peptides to FITC.

  • Notes

    Amount and volume of antibody for conjugation to FITC 

     Kit size   Recommended 
    amount of antibody
    amount of antibody
    Maximum antibody 
    30 µg   3 x 10 µg  3 x 20 µg 3 x 10 µL
    300 µg   3 x 100 µg  3 x 200 µg 3 x 100 µL
    1 mg   1 mg 2 mg 1 mL

    1 Using the maximum amount of antibody may result in less labelling per antibody.

    2 Ideal antibody concentration is 1mg/ml. 0.5 - 1 mg/ml can be used if the maximum antibody volume is not exceeded. Antibodies > 5mg/ml or < 0.5 mg/ml should be diluted /concentrated.


    Buffer Requirements for Conjugation

    Buffer should be pH 6.5-8.5.

    Compatible buffer constituents 
    If a concentration is shown, then the constituent should be no more than the concentration shown. If several constituents are close to the limit of acceptable concentration, then this can inhibit conjugation.

    50mM / 0.6% Tris1 0.1%/1% BSA2 50% glycerol
    0.1% sodium azide PBS Potassium phosphate
    Sodium chloride HEPES Sucrose
    Sodium citrate EDTA Trehalose

    1 Tris buffered saline is almost always ≤ 50 mM / 0.6%
    2 1% BSA gives lower quality conjugates, BSA can also interfere with the use of the conjugated antibody in tissue staining.

    Incompatible buffer constituents

    Thiomerosal Proclin Glycine
    Arginine Glutathione DTT

    If a constituent of the buffer containing your antibody or protein is not listed above, please check the FAQ or contact us.

    Only purified antibodies are suitable for use, ie. where other proteins, peptides, or amino acids are not present: antibodies in ascites fluid, serum or hybridoma culture

FITC Conjugated full length EpCAM Protein

Excellent Excellent 5/5 (Ease of Use)
FITC was succesfully Conjugated with Human EpCAM Protein. It was quite useful.

Better results than with secondary antibody.

Excellent Average 3/5 (Ease of Use)
The kit was easy enough for me to hand this off to an undergraduate, albeit with some explanation of the directions. These were a tad bit confusing at first, and not really clear on the volume of antibody to add (they give you a couple options since the Ab concentration of course matters, but didn't make it clear they were different options).
Otherwise the kit work fantastically with some store bought, pure, concentrated antibody! It actually gave better results than our previous method of using a conjugated secondary antibody when used in Flow Cytometry after doing an Intracellular Stain.
