FLISA-Dtech™ – FLISA Assay Kit
Anti-HER2 antibody (Monkey)

Description

The FLISA-Dtech™ Anti-HER2 Antibody (Monkey) Kit enables the quantitative determination of human anti-HER2 antibodies in monkey serum and plasma, supporting preclinical studies such as pharmacokinetic, pharmacodynamic, and immunogenicity studies.

Based on TR-FLISA (Time-Resolved Fluorescence Linked Immunosorbent Assay) technology, the assay combines the established ELISA format with the high signal intensity and long-lived fluorescence of Bright-Dtech™ fluorescent lanthanide nanoparticles. Time-resolved fluorescence (TRF) detection helps reduce short-lived background fluorescence, supporting sensitive and reliable quantitative detection.

The assay uses Bright-Dtech™ nanoparticles coupled to an anti-human IgG antibody for the specific detection of human anti-HER2 antibodies while minimizing cross-reactivity with endogenous monkey IgG.

 

TR-FLISA Assay Principle

The assay uses an indirect FLISA format in which the microplate is pre-coated with HER2 antigen. Human anti-HER2 antibodies present in the sample bind to the immobilized antigen.

For detection, Bright-Dtech™ nanoparticles coupled to an anti-human IgG antibody bind to the captured human antibodies, generating a fluorescent signal. The long-lived emission of the Bright-Dtech™ nanoparticles enables time-resolved fluorescence measurement using a compatible TRF reader.

The fluorescence signal is proportional to the amount of human anti-HER2 antibodies captured in the assay, allowing their concentration to be determined using a standard curve.

 

Anti-HER2 antibody (Monkey) Kit: Protocol

The FLISA-Dtech™ Anti-HER2 Antibody Kit uses a simple plate-based workflow. The pre-coated and blocked microplate is first prepared according to the protocol, followed by addition of standards or diluted samples. After incubation, Bright-Dtech™–anti-human IgG detection reagent is added. Following the final incubation, the fluorescence signal is measured using a compatible TRF reader.

Please refer to the data sheet for detailed instructions and recommended assay conditions before use.
