ELISA Kits
ELISA kits are widely used immunoassay tools for detecting and measuring proteins, peptides, antibodies, antigens, hormones and biomarkers in research samples. They combine target-specific binding with enzyme-based signal generation, making them suitable for quantitative and qualitative workflows in immunology, molecular biology, biochemistry and cell biology. Gentaur provides ELISA kit options across many targets, species and formats, helping laboratories compare sensitivity, sample type, detection range, documentation and protocol compatibility before ordering.

ELISA workflows rely on specific antigen-antibody recognition and signal development after enzyme-substrate reaction. This makes them useful for measuring defined targets across biological samples such as serum, plasma, supernatant, lysate or tissue extracts. Researchers should confirm the target name, species reactivity and sample compatibility before selecting a kit.
ELISA kits may use sandwich, competitive, direct or indirect formats. Sandwich ELISA is commonly used for many proteins and cytokines, while competitive formats can be useful for smaller molecules or targets with limited binding sites. The best format depends on the target, antibody pair, sample matrix and required sensitivity.
Reliable ELISA data depends on proper standard curve preparation, controls, replicate consistency, washing quality and plate reader settings. Researchers should review detection range, sensitivity, intra-assay variability, inter-assay variability and protocol timing to ensure the kit fits the experimental design.
How to Choose ELISA Kits
Key points to check before selecting products for your research workflow.
- Confirm target name, gene symbol and alternative names.
- Check species reactivity such as human, mouse, rat, bovine, porcine or rabbit.
- Verify sample compatibility, including serum, plasma, supernatant, lysate or tissue homogenate.
- Compare assay format, sensitivity, detection range and standard curve requirements.
- Review protocol length, wash steps, incubation times and plate reader wavelength.
- Check storage conditions, expiration date and required equipment.
- Prefer kits with clear datasheets, validation information and batch documentation.
Common Applications
Frequently Asked Questions
Practical answers for researchers comparing ELISA Kitsproducts.
An ELISA kit is used to detect or quantify a target such as a protein, peptide, antibody, antigen, hormone or biomarker using antibody binding and enzyme-based signal detection.
Check target identity, species reactivity, sample type, assay format, sensitivity, detection range, protocol length and documentation before selecting a kit.
Common sample types include serum, plasma, cell culture supernatant, tissue homogenate, cell lysate and other biological fluids, depending on kit validation.
Sandwich ELISA uses capture and detection antibodies around the target, while competitive ELISA measures signal change caused by competition between sample analyte and labeled analyte.
The standard curve allows researchers to convert signal intensity into concentration and check whether samples fall within the reliable detection range of the assay.
