产品概述
Alexa Fluor® 647 Conjugation Kit / Alexa Fluor® 647 Labeling Kit ab269823 uses a simple and quick process for Alexa Fluor® 647 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 Alexa Fluor® 647 using this kit:
- add modifier to antibody and incubate for 15 mins
- add quencher and incubate for 5 mins
The Alexa Fluor® 647 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 Alexa Fluor® 647.
Custom size conjugation kits up to 100 mg are available on demand. Please contact us to discuss your requirements.

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 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 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.

Direct immunofluorescence - Lightning-Link® Alexa Fluor® 647 Anti-EGFR antibody [E235]
Direct immunofluorescent staining using Recombinant Anti-EGFR antibody [E235] - BSA and Azide free (ab227459) labelled with Alexa Fluor® 647 Conjugation Kit (Fast) - Lightning-Link® (ab269823).
Lightning-Link® Alexa Fluor® 647 Anti-EGFR antibody [E235] conjugate was used to stain wild-type A431 cells (top panel) and MCF7 negative cells (bottom panel). The cells were fixed with 100% methanol at -20°C (5min), permeabilized with 0.1% Triton X-100 for 5 minutes and blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were incubated with 1 µg/ml of LL-Anti-EGFR Alexa Fluor® 647 conjugate (shown in red) or ab227459 (Anti-EGFR antibody, unlabelled control) overnight at +4°C. Ab227459 treated cells only were incubated with ab150077 at 1/1000 dilution for 1 hour at room temperature (shown in green).
Nuclear DNA was labelled in blue with DAPI.
Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

(a-c) Chip description and operation. (a) Presentation of the chip layout. Beads and reagents can be successively injected through the two inlets visible on the left. The device consists of three incubation lines upstream and three concentration lines downstream, at the end of which the beads are accumulated in clusters (shown here in red). (b) Illustration of a sandwich immunoassay used for detection of biomarkers. The analyte we aimed to detect was captured by the bead decorated with capture antibody (cAb) and detection was performed thanks to the fluorescently labeled detection antibody (dAb). (c) Presentation of the successive steps performed on-chip to operate the platform, namely, (1) beads' loading, (2) incubation with detection antibodies and (3) release from the incubation line, (4) clustering in the concentration region, and (5) discarding through the outlet. For the sake of clarity, the species bound to the beads and the electrically activated arrays of electrodes are indicated for each step. (d-f) On-chip incubation of Neutrophil Gelatinase-Associated Lipocalin (NGAL) biomarker. (d) Observation of the small beads' clusters (circled in pink) before and after 15 min of incubation. The fluorescence signal arose from the binding of dAb-NGAL complex to cAb-decorated beads dielectrically trapped in the regions upstream to the electrode line. Three NGAL concentrations were injected in separate experiments, namely, 1 ng/mL, 10 ng/mL, and 100 ng/mL. (f) Fluorescence signal as a function of the incubation time for different NGAL concentrations. After 15 min all concentrations provided a signal greater than the control experiment, consisting of an injection of a solution in absence of NGAL molecules. The error bars were obtained by measuring the fluorescent signal from 10 clusters.
