The selling size of this product is now based on the amount of antibody that can be conjugated with the kit; the amount of antibody advised that can be used with the kit has also been updated to reflect what will give the best conjugation results. The quantity and formulation of reagents provided have not changed, if you have been previously using the kit successfully with a different amount of antibody, there is no need to change the way that you are using the kit.
1Ideal antibody concentration is 1mg/ml. 0.5 - 1 mg/ml can be used if the maximum antibody volume is not exceeded. Antibodies > 1 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
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.
Storage instructionsStore at -20°C. Please refer to protocols.

- R Phycoerythrin
Robinson, Andrew P., et al used PE / R-Phycoerythrin Conjugation Kit - Lightning-Link® (ab102918) as part of characterizing oligodendroglial populations. They used the kit to conjugate PE / R-Phycoerythrin to Mouse monoclonal anti-GALC antibody for use in flow cytometry.
SJL/J mice were immunized with PLP139-151 and scored daily for clinical disease. A cohort of SJL/J mice was sacrificed, and spinal cords were analyzed by flow cytometry (n=5). (A) Cells were distinguished from debris by forward and side scatter then singlet cells were gated. Live cells were gated by dead cell exclusion, and CNS resident cells were identified as CD45- or CD45low. (B) Oligodendroglial cells were defined by double positive staining: A2B5+PDGFRalpha+ early OPCs, A2B5+NG2+ intermediate OPCs, NG2+O4+ late OPCs, O4+MOG+ pre-myelinating oligodendrocytes, and GALC+MOG+ mature oligodendrocytes.
Bigler MB et al. used ab102918 to assess expression of the epinephrine receptor (ADRB2) on CD3- CD56+ lymphocytes by flow cytometry.
Ayoglu B et al. used ab102918 to detect complement activation driven C3 deposition on beads.
For measuring the background, classical, lectin & alternative and only alternative pathway activation, a serially diluted serum sample (1∶1–1∶160) was applied to empty, human IgG. The assay buffer for serum dilution contained either Ca2+-Mg2+, which promotes complement activation, or EDTA, which blocks complement activation. Plot displays for each serum dilution the respective median fluorescence intensity (MFI) value against varying concentrations of human IgG.
