Alexa Fluor® 555 Conjugation Kit (Fast) - Lightning-Link®

Product details

Alexa Fluor® 555 Conjugation Kit - Lightning-Link® (ab269820) uses a simple and quick process for Alexa Fluor® 555 labeling / conjugation of antibodies. It can also be used to conjugate other proteins or peptides.

To conjugate an antibody to Alexa Fluor® 555 using this kit:
- add modifier to antibody and incubate for 15 min
- add quencher and incubate for 5 min

The Alexa Fluor® 555 conjugated antibody can be used immediately in Flow cytometry, 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 antibody purification and concentration kits.
Custom size conjugation kits up to 100 mg are available on demand. Please contact us to discuss your requirements.

Amount and volume of antibody for conjugation to Alexa Fluor^® 555

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.

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

Incompatible buffer constituents

If a constituent of the buffer containing your antibody or protein is not listed above, please 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 media are incompatible.

Storing and handling conjugation kits

Lyophilized Lightning-Link^® components are hygroscopic.

Kits are intentionally shipped at ambient temperature with silica gel to avoid exposure to moisture. Upon receipt, store the kit frozen and protect from moisture. Before opening the outer container, allow the lyophilized components to reach room temperature to minimize condensation.
