Direct immunofluorescent staining using Recombinant Anti-Ki67 antibody [EPR3610] - BSA and Azide free (ab209897) labelled with Alexa Fluor® 488 Conjugation Kit (Fast) - Lightning-Link® (ab236553).
Lightning-Link® Alexa Fluor® 488 Anti-Ki67 antibody [EPR3610] conjugate was used to stain Ki67-wild-type HAP1 cells (top panel) and Ki67-knock-out HAP1 cells (bottom panel). The cells were fixed with 4% paraformaldehyde (10 min), 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-Ki67 Alexa Fluor® 488 (shown in green) or ab209897 (Anti-Ki67 antibody, unlabelled control) overnight at +4°C. ab209897 treated cells only were incubated with ab150087 at 1/1000 dilution for 1 hour at room temperature (shown in red).
Nuclear DNA was labelled in blue with DAPI.
Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

Bardhan, Kankana, et al used Alexa Fluor® 488 Conjugation Kit (Fast) - Lightning-Link® (ab236553) as part of examining PD-1pY248+ (pPD-1) expression in human T cells. They used the kit to conjugate Alexa Fluor® 488 to Anti-PD-1pY248 antibody for use in flow cytometry.
pPD-1 is predominantly expressed in CD8+ TCM cells. CCR7 and CD45RO markers were used to identify central memory (TCM) and effector memory (TEM) T cells. After gating on CD45RO expression, TCM (CD45RO+CCR7+) and TEM (CD45RO+CCR7−) CD4+ and CD8+ T cells were identified by assessing expression of CCR7. In TCM and TEM populations, expression of PD-1 was determined and, subsequently, expression of pPD-1 (pPD-1-Y248) was assessed in the PD-1+ population within each subset. Results are representative of six separate experiments.

Soldevila, Ferran et al used Alexa Fluor® 488 Conjugation Kit - Lightning-Link® (ab236553) as part of examining myeloid cells in the porcine palatine tonsil. They used the kit to conjugate Alexa Fluor® 488 to anti-pig CD4α antibody for use in confocal microscopy.
In situ localization of the CD14+ cells and plasmocytoid dendritic cells in porcine palatine tonsil. CD14+ cells and pDCs were localized by confocal microscopy following ethanol fixation of tonsil slices. The areas assessed included the follicle (F), the interfollicular region (IFA), the crypt (C). The tissue was stained using panel 1 antibodies; white arrow CD14+ cells and yellow arrow pDCs. Images are representative of at least two images from each section, from three different pigs. Objective used : (A) 63× oil immersion. Scale bars as shown.

Alexa Fluor® 488 Conjugation Kit (Fast) - Lightning-Link®.
A polyclonal antibody was purchased from a commercial source and conjugated to Alexa Fluor® 488 using Alexa Fluor® 488 Conjugation Kit (Fast) - Lightning-Link® (ab236553) and to CF™488A dye using a competitor conjugation kit. The conjugates were tested by ELISA and the fluorescence measured at 523nm after excitation at 487nm. The Abcam conjugate out-performs the competitor.
Product details
Alexa Fluor® 488 Conjugation Kit / Alexa Fluor® 488 Labeling Kit (ab236553) uses a simple and quick process for Alexa Fluor 488 labeling / conjugation of antibodies. It can also be used to conjugate other proteins or peptides.
To conjugate an antibody to Alexa Fluor® 488 using this kit:
- add modifier to antibody and incubate for 15 mins
- add quencher and incubate for 5 mins
The Alexa Fluor® 488 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.
Custom size conjugation kits up to 100 mg are available on demand. Please contact us to discuss your requirements.
This product is manufactured by Expedeon, an Abcam company, and was previously called Lightning-Link® Rapid Alexa Fluor® 488 Labeling Kit. 332-0015 is the same as the 1 mg size. 332-0010 is the same as the 3 x 100 ug size. 332-0030 is the same as the 3 x 10 ug size. 332-0005 is the same as the 100 μg size.
Amount and volume of antibody for conjugation to Alexa Fluor® 488
| Kit size | Recommended amount of antibody1 |
Maximum amount of antibody |
Maximum antibody volume2 |
| 3 x 10 μg | 3 x 10 μg | 3 x 20 μg | 3 x 10 μL |
| 100 μg | 100 μg | 200 μg | 100 μL |
| 3 x 100 μg | 3 x 100 μg | 3 x 200 μg | 3 x 100 μL |
| 1 mg | 1 x 1 mg | 1 x 2 mg | 1 x 1 mL |
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 > 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 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.
