• Product name
    HRP Conjugation Kit
  • Product overview

    HRP Conjugation Kit ab102890 uses a simple and quick process to conjugate an antibody to HRP. It can also be used to conjugate other proteins or peptides.

    To conjugate an antibody to HRP using this kit:
    (check protocol booklet first)
    - add modifier reagent to antibody and incubate for 3 hrs
    - add quencher reagent and incubate for 30 mins
    The conjugated antibody can be used immediately in WB, ELISA, IHC etc. No further purification steps are required and 100% of the antibody is recovered for use.

    Learn about buffer compatibility below; if your buffer is incompatible or antibody concentration is too low, please use our rapid antibody purification and concentration kits. Use our FAQs to learn more about the technology, or about conjugating other proteins and peptides to HRP.

  • Notes

    Amount and volume of antibody for conjugation to HRP
    (up to the following amounts)

     Kit size   Amount of antibody
    at 4:1 molar ratio1 
    Amount of antibody
    at 1:1 molar ratio1
    Maximum antibody
    30 µg   3 x 10 µg  3 x 40 µg 3 x 10 µL
    100 µg   100 µg   400 µg 100 µL
    300 µg   3 x 100 µg  3 x 400 µg 3 x 100 µL
    1 mg   1 mg 4 mg 1 mL

    1 Optimal HRP:antibody molar ratio is 4:1. Antibodies often also perform well at a 1:1 molar ratio.

    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.


    Sample Buffer Requirements

    Compatible buffer constituents
    (up to the concentrations shown, and pH 6.5-8.5):

    50mM Tris 0.1%/1% BSA* 0.1% gelatin 
    0.1% sodium azide** PBS pH6.5-8.5 50% glycerol
    0.15M sodium chloride 50mM HEPES 0.02M potassium phosphate
    0.001% Tween 5% Trehalose EDTA

    * 1% BSA gives lower quality conjugates.
    ** Sodium azide irreversibly inhibits HRP; antibodies with azide should be purified before using the HRP conjugation kit.

    Incompatible buffer constituents
    (in addition to any compatible constituents above the acceptable concentrations):

    Urea  >50mM Imidazole  Glycine
    Ethanolamine DTT Mercaptoethanol
    Thiomerosal Other thiols  Proclin

    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.
