HRP Conjugation Kit - Lightning-Link®(AB102890)

Product details HRP Conjugation Kit - Lightning-Link^®(AB102890)

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.

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

This product is manufactured by Expedeon, an Abcam company, and was previously called Lightning-Link^® HRP Labeling Kit. 701-0004 is the same as the 5 mg size. 701-0003 is the same as the 5 x 1 mg size. 701-0000 is the same as the 3 x 100 ug size. 701-0030 is the same as the 3 x 10 ug size. 701-0010 is the same as the 100 μg size. 701-0002 is the same as the 1 mg size.

Buffer Requirements for Conjugation

Buffer should be pH 6.5-8.5.

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.

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).

This illustration demonstrates a general procedure of how Lightning-Link^® labeling technology enables the direct labeling of antibodies or proteins.

Simply pipette your antibody or biomolecule of choice into the vial of a lyophilized mixture containing the label of interest and incubate for around 3 hours. Please see the ab102890 protocol booklet for more details.

HRP conjugation kit ab102890 is used by Abcam extensively in ELISA development. It is used for development / manufacturing of Abcam's SimpleStep ELISA^® kits, including the Frataxin ELISA kit ab176112 used to produce the image above.

Transformed B lymphocyte cells from Friedreich's Ataxia (FA) samples were compared to heterozygous carrier B lymphocyte cells (Carrier) and control B lymphocyte cells (Control). B lymphocyte cell extracts were analyzed across a 7-point titration (0.1-100 μg/mL) and frataxin levels were interpolated from the standard curve. Average interpolated values of Frataxin are plotted.

ELISA - HRP Conjugation Kit Lightning-Link.

Cervin, Jakob, et al used HRP Conjugation Kit - Lightning-Link^® (ab102890) as part of examining binding of Cholera Toxin subunit B (CTB) to blood group antigen LewisX (LeX). They used the kit to conjugate HRP to CTB and G33D (mutated version of CTB) for use in ELISA.

ELISA with titrated amounts human serum albumin-linked oligosaccharides (HSA-OS), immobilized to wells and detected with (B) CTB-HRP and (C) G33D-HRP. Graph shows absorbance values from three independent experiments.

HRP Conjugation Kit - Lightning-Link^® labeling C3C antibody for competitive ELISA.

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.
