    B-Phycoerythrin Conjugation Kit
  • Product overview

    B-Phycoerythrin Conjugation Kit ab102871 uses a simple and quick process to conjugate an antibody to B-Phycoerythrin. It can also be used to conjugate other proteins or peptides.

    To conjugate an antibody to B-Phycoerythrin 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 B-Phycoerythrin.



  • Notes

    Amount and volume of antibody for conjugation to B-Phycoerythrin.

     Kit size   Recommended 
    amount of antibody
    Maximum antibody 
    180 µg   3 x 60 µg 3 x 60 µL
    60 µg   60 µg  60 µL
    600 µg   600 µg 600 µL

    1 Kit is designed to give a 1:1 molar ratio of antibody to PE after conjugation.

    2 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.

    The selling size of this product has been changed – it is now based on the amount of antibody that can be conjugated with the kit, not the amount of PE mix provided. The quantity of reagents provided have not changed or the amount of antibody that can be conjugated.


    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 media are incompatible.

Customer reviews and Q&As


Thank you for contacting us.

We currently do not have any publication information regarding its use in sheep BMSCs. I am sorry we can't offer any tested data. This antibody however was tested with sheep lysates and gave good staining so it is more likely that the antibody with detect sheep CD34 target. The use of ab81289 (https://www.abcam.com/CD34-antibody-EP373Y-ab81289.html) comes with Abcam Abpromise guarantee which states we will refund your money if the antibody fails to detect the CD34 target.


I can provide further opinion about CD90 antibodies could you send me goat CD90 protein sequence?
