• Product name
    PerCP Conjugation Kit
  • Product overview

    PerCP Conjugation Kit ab102907 uses a simple and quick process to conjugate an antibody to PerCP. It can also be used to conjugate other proteins or peptides.

    To conjugate an antibody to PerCP using this kit:
    - add modifier to antibody and incubate for 3 hrs
    - add quencher and incubate for 30 mins
    The 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 PerCP.


  • Notes

    Amount and volume of antibody for conjugation to PerCP

     Kit size   Recommended maximum
    amount of antibody
    Maximum antibody 
    30 µg   3 x 10 µg 3 x 10 µL
    100 µg   100 µg  100 µL
    300 µg   3 x 100 µg  3 x 100 µL
    1 mg   1 mg 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 > 5mg/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%/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 1% BSA gives lower quality conjugates, 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

Thank you for your call yesterday and for your patience while I have been in touch with the scientists in the lab regarding your enquiry.

My colleagues have pointed out that the protein should be concentrated for the best results. The entire 250 uL should not be added to the single 100 ug vial of conjugate even though the protein is less concentrated. The conjugation will not work with 250 uL of sample volume. If the protein can not be concentrated, you can try with the dilute protein but the 250 uL will need to be split over the multiple vials of conjugate, so that no more than 100 uL will be added per vial. This should give some conjugated product but please note that the results will not be optimal.

I hope this information will be useful, but please let me know if you have any further questions or need anything else regarding these kits, and I will be happy to help. Have a nice day.

Thank you for contacting us.

Unfortunately, I am unable to tell you the number of Cy5.5 molecules. The amount of Cy5.5 per PerCP in the PerCP/Cy5.5 conjugation kit has been optimised to give excellent performance.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
