Product nameFITC Conjugation Kit (Fast)
See all FITC kits
FITC Conjugation Kit (Fast) (ab188285) 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 15 mins
- add quencher and incubate for 5 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.
Amount and volume of antibody for conjugation to FITC
Kit size Recommended
amount of antibody1
amount of 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
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 media are incompatible.
