Product Overview

EnkiLife HRP labeling kit contains multiple components for labeling antibody , such as the activated lyophilized HRP, labeling buffer, and other chemical reagents, enabling easy and reliable antibody labeling.

Product Features

• Activated HRP with extended arm:The cross-linker used in the kit has an extended arm to ensure that the application effect is not affected by protein steric hindrance.
• Site-specific conjugation:Optimized site-specific conjugation technology ensures uniform antibody labeling and improves efficiency.
• Rapid process:The simple procedure allows for efficient labeling completion in as fast as 3 - 4 hours.
• Highly active HRP：The HRP configured in this kit is of high purity and high activity, Enzyme activity is 120 - 200 U/mg，freeze-dried powder can be stably stored at -20°C for at least 12 months.
• User-friendly operation:Each HRP reagent is pre-optimized for corresponding antibody amounts. No complex calculations are required if the antibody sample meets the labeling conditions. The solid HRP ensures batch stability.
• Comprehensive reagents: The kit includes a labeling preservation solution, covering the entire process from labeling to preservation. No additional reagents are needed, making the process worry-free and convenient.

Kit Specifications

* * Ultrafiltration tube molecular weight cutoff: 50KDa

Labeling Principle

This kit utilizes the cysteine characteristics of the antibody and the free amino groups on the dye to covalently couple the antibody molecule with the dye using a directed docking coupling technique.

Data of HRP labeling kit  application

Western Blot(WB) Analysis

Use the HRP labeling kit (RE80004p) to label two kinds of goat anti-mouse IgG antibodies, and then conduct WB detection to evaluate the effect.

• Sample: Mouse IgG, samples 1–6 are 500 ng, 50 ng, 5 ng, 500 ng, 50 ng, and 5 ng, respectively.
• Antibody:
  HRP-labeled goat anti-mouse IgG 0.5 mg/ml (diluted 1:2000):
  1–3: HRP-goat anti-mouse IgG (H+L)
  4–6: HRP-goat anti-mouse IgG, F(ab)₂ fragment
  

Conclusion: The antibody staining showed clear signals with a expectant signal-to-noise ratio. RE80004P kit  is suitable for labeling goat anti-mouse IgG.

Immunohistochemistry(IHC) Analysis

Use the HRP labeling kit (SKU: RE80004p), label goat anti-mouse IgG,then conduct IHC detection (DAB staining solution）to evaluate the effect.

• Sample:  Human liver tissue paraffin sections
• Antibody:
  Primary antibody: Vimentin mouse monoclonal antibody(diluted 1:100)
  Secondary antibody:HRP-goat anti-mouse IgG  preparaed with  HRP labeling kit (SKU: RE80004p) with a 1:200 dilution
  

Conclusion: The Secondary antibody preparaed with HRP labeling kit staining showed clear signals with a  expectant nuclear expression.
