Overview

  • Product name

    Cy5® Conjugation Kit (Fast) - Lightning-Link®
  • Product overview

    Cy5® Conjugation Kit / Cy5® Labeling Kit (ab188288) uses a simple and quick process for Cy5 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 Cy5 using this kit:
    - add modifier to antibody and incubate for 15 min
    - add quencher and incubate for 5 mins
    The Cy5 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 Cy5.


    Custom size conjugation kits up to 100 mg are available on demand. Please contact us to discuss your requirements.

  • Notes

    This product is manufactured by Expedeon, an Abcam company, and was previously called Lightning-Link® Rapid Cy5 Labeling Kit. 342-0005 is the same as the 100 µg size. 342-0010 is the same as the 3 x 100 ug size. 342-0030 is the same as the 3 x 10 ug size. 342-0015 is the same as the 1 mg size.

    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 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.

    Lindenburg, Laurens, et al used Cy5® Conjugation Kit (Fast) - Lightning-Link® (ab188288) as part of examining microemulsion-based bead display screening of the ZIgE SpliMLiB library. They used the kit to conjugate Cy5® to Native human IgE protein (Azide free) (ab65866) for use in FACS.
    (A) Schematic overview of a round of SpliMLiB-enabled directed evolution of ZIgE. SpliMLiB beads (i) were singly encapsulated in emulsion IVTT at 37°C for 1 h (ii), sufficient time to allow for both ZIgE-SpyCatcher variants' expression as well as for their SpyTag-SpyCatcher-mediated immobilisation on the bead surface, after which the emulsion was broken, and the washed beads were exposed to Cy5-labelled IgE (iii), followed by flow cytometric sorting of beads based on Cy5 signal (iv). (B) Representative histogram recorded during the flow cytometric sorting of SpliMLiB ZIgE library beads. The range of fluorescence intensity used for each of the sorting gates 1-4 is indicated. (C) Analysis of pooled, recovered and subcloned DNA from the sorting gates set out in panel B. DNA was used to express protein in IVTT under bulk, i.e. non-emulsion conditions, in the presence of SpyTag-functionalised microbeads. The microbeads, having captured the SpyCatcher fusion proteins, were then incubated with 200 nM IgE-Cy5 and analysed by flow cytometry. Cy5 fluorescence intensity was normalised to a sample prepared from beads exposed to purified ZIgEwild-type-SpyCatcher protein (WT, grey bar). Negative control (NC) was beads not exposed to any ZIgE-SpyCatcher protein. (D) Analysis of bacterially expressed & purified variants derived from the stringently sorted library output from FACS sorting gate 4. Beads that had been bound with ZIgE-SpyCatcher variants were incubated with 200 nM IgE-Cy5 and analysed by flow cytometry. ZIgEwild-type-SpyCatcher (labelled WT) was included as control and was used to normalise all fluorescent values. The variant showing the highest Cy5 median signal (variant 33, marked by a single asterisk) and second highest (variant 44, marked by a double asterisk) signal were taken forward for further analysis. (E) As panel D, except for 48 randomly picked clones derived from the unsorted SpliMLiB input library beads. (F) Frequencies of amino acids encountered in selected variants displaying a higher binding signal than ZIgEwild-type-SpyCatcher (17 in total).

Question

I have recently purchased (ab188288 – Cy5 Fast Conjugation Kit) to label an Antibody for a flowcytometry. But the storage buffer of the antibody contains 1XPBS, 1%BSA, 20% Glycerol (pH7). And 0.01% Thimerosal was added as a preservative, would this has an effect on the conjugation. Should I do dialysis for the antibody before labelling?

Answer

Only the BSA seems to be a problem, its concentration should be 0.1%-0.5%. The ideal way is to remove BSA, we have kit for this https://www.abcam.com/BSA-Removal-Kit-ab173231.html. Alternatively you can give it a go however it might affect the efficiency of the kit. Please check the information on booklet;

10.2 Common non-buffering salts (e.g. sodium chloride), chelating agents (e.g.EDTA), and sugars have no effect on conjugation efficiency. Azide (0.02 to 0.1%) and BSA (0.1 to 0.5%) have little or no effect. Glycerol up to 50% has no effect.

Question

Are fluorescent conjugation kits (Cy5 labeling kit) suitable for the labeling of M13 bacteriophage through amine group?

Asked on Jan 15 2015

Answer

M13 bacteriophages have not been tested with our labeling kits. However, as long as it contains some primary amines which are available for labeling, then there should be no reason why this would not work. As for antibodies, it is important that the buffer does not contain any free amines or other unsuitable substances. Please see below for details of (un)compatible formulations:


Additives such as salts (e.g NaCl), sugars (e.g. sucrose) and chelators (e.g. EDTA) have no effect on the labeling reaction. We recommend avoiding nucleophiles such as amino acids (e.g. glycine), blockers (e.g. ethanolamine) and thiols (DTT, mercaptoethanol) that could interfere with the conjugation reaction.

Compatible additives:
up to 20mM Tris
up to 0.1% BSA (BSA up-to 1% will work but yield lower quality conjugates)
up to 0.1% gelatin
up to 0.1% sodium azide
PBS pH6.5-8.5
up to 50% glycerol
0.15M sodium chloride
50mM HEPES
0.02M potassium phosphate
0.001% Tween
Proclin 300
5% Trehalose


Incompatibile additives:
Tris above 20mM
Urea
50mM Imidazole
Glycine
Ethanolamine
DTT
Mercaptoethanol


Finally, the M13 bacteriophage will be a different molecular weight to that of an antibody, and the protocol will therefore have to be adjusted to allow for the size difference. It is difficult for us to provide any advice, as I do not know the MW of the bacteriophage, but I would generally recommend that you carry out a titration of different concentrations, in order to determine the best set-up for your assay.
