This product is manufactured by Expedeon, an Abcam company, and was previously called Lightning-Link® Fluorescein Labeling Kit. 707-0005 is the same as the 100 µg size. 707-0010 is the same as the 3 x 100 ug size. 707-0030 is the same as the 3 x 10 ug size. 707-0015 is the same as the 1 mg size.
Amount and volume of antibody for conjugation to FITC
Kit size | Recommended
amount of antibody1 | Maximum
amount of antibody | Maximum antibody

3 x 10 µg | 3 x 10 µg | 3 x 20 µg | 3 x 10 µL |
100 µg | 1 x 100 µg | 1 x 200 µg | 1 x 100 µL |
3 x 100 µg | 3 x 100 µg | 3 x 200 µg | 3 x 100 µL |
1 mg | 1 x 1 mg | 1 x 2 mg | 1 x 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 > 2 mg/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% BSA | 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%
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.
