Product nameAPC Conjugation Kit - Lightning-Link®
APC Conjugation Kit / APC Labeling Kit (ab201807) uses a simple and quick process for APC labeling / conjugation of antibodies. It can also be used to conjugate other proteins or peptides. Learn about our antibody labeling kits and their advantages.
To conjugate an antibody to APC using this kit:
- add modifier to antibody and incubate for 3 hours
- add quencher and incubate for 30 mins
The APC 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 APC.
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 APC
Kit size Recommended
maximum amount of antibody
3 x 10 µg 3 x 10 µg 3 x 10 µL 100 µg 1x 100 µg 1 x 100 µL 3 x 100 µg 3 x 100 µg 3 x 100 µL 1 mg 1 x 1 mg 1 x 1 mL
1 Ideal 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% 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 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.
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.

Bouchery, Tiffany, et al used APC Conjugation Kit - Lightning-Link® (ab201807) as part of examining methods for arresting hookworm development. They used the kit to conjugate APC to anti-Na-APR-1 antibody for use with live hookworms in fluorescence microscopy.
Infective L3 stage hookworms were fed in vitro for 24 hr with RBC and treated with 10 μg of 11F3-APC monoclonal antibody against Na-APR-1 or with an isotype matched-RELM-APC control antibody. Larvae were allowed to empty their digestive contents for 2 hours in fresh DMEM before internal labelling was evaluated by confocal microscopy. Data representative of 50 larvae cultured in 3 independent experiments.
Haque, Nasreen S., Akaash Tuteja, and Niloufar Haque used APC Conjugation Kit - Lightning-Link® (ab201807) as part of examining as part of examining embryoid body formation. They used the kit to conjugate APC to anti-CCR8 antibody for use in immunofluorescence.
Anti CCL1 inhibits the expression of CCR8 and FoxP3 in mouse mesenchymal stem cells (mMSCs). Untreated (5a,-c) and anti-CCL1 treated (5d,-,f) cells were subjected to immunoflourescence with antibodies against FoxP3 (green;5b and e) or CCR8 (red;5c and f).

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+PDGFRα+ early OPCs, A2B5+NG2+ intermediate OPCs, NG2+O4+ late OPCs, O4+MOG+ pre-myelinating oligodendrocytes, and GALC+MOG+ mature oligodendrocytes.

They used the kit to conjugate APC to anti-human 4β7 antibody for use in flow cytometry.
A. Flow cytometric analysis of CD4, CCR5 and α4β7 expression in the A3R5.7 cell line. 0.5 x 106 cells were singly stained for 30 minutes with fluorochrome-conjugated antibodies as shown followed by fixation in 2% paraformaldehyde. Data are representative of at least two independent experiments. Isotype controls are shown in grey. Nearly all cells were positive for CD4 and CCR5 while approximately half were positive for α4β7.
B. Comparison of cell surface CD4, CCR5 and α4β7 receptor densities in various cell targets. 0.5 x 106 cells were stained with fluorochrome-conjugated antibodies and compared to defined populations of similarly stained Quantum Simply Cellular beads. PBMC were stimulated with CD3.8 bi-specific antibody in the presence of 50U/mL rhIL-2. Assuming monovalent antibody-to-surface receptor binding, the Antibody Binding Capacity (ABC) calculated is equivalent to receptors/cell. Data represents the mean of two separate experiments. TZM-bl cells express high levels of CD4 and CCR5 but are negative for α4β7 while A3R5.7 cells possess CCR5 and α4β7 densities more similar to PBMC. CD4 expression on TZM-bl was beyond assay range.
Del Cid N et al. used ab201807 as part of examining antigen cross-presentation.
They used the kit to conjugate APC to ovalbumin (OVA) and ovalbumin-calreticulin fusion protein (OVA-CRT) for use in in-gel fluorescence and flow cytometry.
OVA-CRT and OVA were labeled with allophycocyanin. (C) Labeling intensity was determined by fluorescence imaging of the proteins after separation by SDS-PAGE (inset). Fluorescence intensity was quantified for the indicated proteins. (D) Binding of fluorescent proteins to BMDC was assessed by flow cytometry. BMDC were incubated with labeled proteins on ice before being analyzed by flow cytometry. BMDC not incubated with proteins are depicted as a grey filled.
