Product nameHRP Conjugation Kit - Lightning-Link®
HRP Conjugation Kit / HRP Labeling Kit ab102890 uses a simple and quick process for HRP 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 HRP using this kit:
- add modifier to antibody and incubate for 3 hrs
- add quencher and incubate for 30 mins
The HRP 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 HRP.
Custom size conjugation kits up to 100 mg are available on demand. Please contact us to discuss your requirements.

1 Recommended amount of antibody will give an HRP:antibody molar ratio of 4:1. Antibodies often also perform well at the maximum amount of antibody which is 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 > 4 mg/ml or < 0.5 mg/ml should be diluted /concentrated.
Buffer Requirements for Conjugation
Buffer should be pH 6.5-8.5.
Buffer constituent compatibility
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.
Compatible buffer constituents 50mM / 0.6% Tris1 0.1% BSA 50% glycerol 0.1% sodium azide2 PBS Potassium phosphate Sodium chloride HEPES Sucrose Sodium citrate EDTA Trehalose
1 Tris buffered saline is almost always ≤ 50 mM / 0.6%
2 Sodium azide irreversibly inhibits HRP; antibodies with azide should be purified before using the HRP conjugation kit.
Incompatible buffer constituents Thiomerosal Proclin Glycine Arginine Glutathione DTT
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.
Storage instructionsStore at -20°C. Please refer to protocols.

Parkash, Om, et al used HRP Conjugation Kit - Lightning-Link® (ab102890) as part of the development and evaluation of a biosensor based on screen-printed carbon electrodes (SPCEs) for the detection of dengue-specific immunoglobulin M (IgM) antibodies. They used the kit to conjugate HRP to anti-dengue antibody for use in conjugation.
(A) Schematic diagram of the screen printed carbon electrode (SCPE)-based dengue IgM biosensor. The biosensor was constructed by sequentially adding optimised concentration of anti-human IgM capture antibody, blocking agent, human IgM antibody or serum sample, dengue antigen and detection antibody, with washing steps in between. Electrochemical signal was generated following addition of TMB substrate. (B) Comparison of various immobilisation techniques for the goat anti-human IgM capture antibody. NC: negative control consisting of a dengue IgM negative serum sample; PC: dengue IgM positive serum sample. (C) Field Emission Scanning Electron Microscopy (FESEM) surface images of (left panel) a bare carbon electrode and (right panel) a carbon electrode modified with an anti-human IgM antibody using the streptavidin/biotin immobilisation system. Both capture and detection antibodies were labeled using Lightning-Link® conjugation kits (ab201796 and ab102890).

Rasmussen DG et al. used ab102890 to determine levels of C3C by competitive ELISA.
(A) Standard curve and inhibition of the competitive ELISA signal using healthy human serum, (B) human heparin plasma and (C) human EDTA plasma. The native material was run from undiluted and up to 8-fold diluted as indicated. (D) Neo-epitope specificity of the C3C ELISA was shown by comparing reactivity towards an elongated peptide, i.e. a peptide with an additional amino acid at the N-terminal generated by cleavage, a non-sense peptide, i.e. a peptide with a different sequence, and the standard peptide. The standard peptide (i.e. standard curve), elongated peptide, and non-sense peptide were diluted 2-fold from 100 ng/mL. The data is presented as percent (%) of background absorbance, which is the absorbance with only assay buffer present, as a function of peptide concentration.
