1 Using the maximum amount of antibody may result in less labeling 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 > 2mg/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.

Eichwald, Catherine, et al used Atto 488 Conjugation Kit (Fast) - Lightning-Link® (ab269896) as part of examining the distribution of acetylated-microtubules (MTs) with respect to viroplasms. They used the kit to conjugate Atto 488 to mouse monoclonal anti-alpha tubulin antibody for use in immunocytochemistry/immunofluorescence (ICC/IF).
At 6 hours post-infection, SA11-infected CV-1 cells [multiplicity of infection (MOI); 25 VFU/ml] were fixed with methanol and immunostained for detection of viroplasms in red (anti-NSP5 antibody followed by a secondary antibody conjugated to Alexa 594), acetylated-MTs in cyan (mouse mAb anti-acetylated alpha-tubulin followed by a secondary antibody conjugated to Alexa 647), MTs in green (mouse mAb anti-alpha tubulin directly conjugated to Atto 488 (green)) and nuclei in blue (DAPI). Z-stack images were acquired by high-resolution CLSM and subsequently, 3D-reconstructions were performed using surface and filament algorithms from the surpass model of the Imaris 7.0 software (Bitplane, Switzerland). 3D-reconstructions are visualized from the topside (A, B and C) and the bottom side (D, E and F) of the preparation. Images show viroplasms (from A to F), acetylated-MTs (A, B, D and E) and MTs (A, C, D and F). Scale bars are 5 µm.
Simanjuntak, Yogy, et al used Atto 488 Conjugation Kit (Fast) - Lightning-Link® (ab269896) as part of examining the mechanisms of viral invasiveness in Japanese encephalitis virus (JEV). They used the kit to conjugate Atto 488 to Japanese encephalitis virus (JEV) for use in immunocytochemistry.
BE(2)C cells were infected with fluorescently labeled JEV (Atto488) for 2 h at room temperature with or without anti-integrin β3 and anti-vimentin antibody (0.75 and 1.5 μg/ ml). Mouse immunoglobulin G (IgG) was used as antibody control (1.5 μg/ml). Cells with or without antibody (1.5 μg/ ml) were stained with Alexa Fluor 568 phalloidin for F-actin (red) and Hoechst for nuclei (blue). Confocal microscopy images (630× original magnification).
Veldkamp, Marieke W., et al used Atto 488 Conjugation Kit (Fast) - Lightning-Link® (ab269896) as part of examining electrophysiological effects of the neuropeptide Sub-P in isolated rabbit atrial myocytes, and in Langendorff-perfused and in situ rabbit heart. They used the kit to conjugate Atto 488 to anti-NK3R antibody for use in immunohistochemistry (frozen sections).

Robinson, Andrew P., et al used Atto 488 Conjugation Kit (Fast) - Lightning-Link® (ab269896) as part of characterizing oligodendroglial populations. They used the kit to conjugate Atto 488 to Rat anti-PDGFRalpha antibody, clone APA5, 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+PDGFRα+ early OPCs, A2B5+NG2+ intermediate OPCs, NG2+O4+ late OPCs, O4+MOG+ pre-myelinating oligodendrocytes, and GALC+MOG+ mature oligodendrocytes.
Olling A et al. used ab269896 as part of examining the role of toxins in the pathogenicity of Clostridium difficile.
They used the kit to conjugate Atto 488 to TcdA1–1874 toxin for use in flow cytometry.
Binding of fluorescent labeled TcdA-PE/Cy5 and TcdA1–1874-Atto488 to HT29 and CHO-C6 cells was investigated by FACS analysis. Right shift of the black curve illustrates toxin binding which was detected through fluorescence emission at 667 nm for TcdA and at 523 nm for TcdA1–1874, respectively. Due to different ratio of fluorophor and toxin, fluorescence intensity of TcdA-PE/Cy5 cannot directly be compared with TcdA1–1874-Atto488.
Zeinolabediny Y et al. used ab269896 as part of examining the toxicity of p17 protein assemblies.
They used the kit to conjugate Atto 488 to p17 protein for use in microscopy.
