Creative Biolabs is a world leader in the development of ELISA based kits and provides a wide range of assay kits for specific detection of disease-related proteins. Our methods have been validated by international bodies and numbers of different assay kit formats are available. Our ELISA kits allow the clients to quickly narrow down results by detection target, species reactivity, application or conjugate. Methods based on enzyme labels have been developed for colorimetric immunoassays in Creative Biolabs. Our professional team is optimized to help you with high-quality and cost-effective testing service to make your project a success.

Advantages of Colorimetric Immunoassay (CIA)

The important role of disease-associated protein detection in biological research, clinical diagnostics, and medical treatment has prompted scientists to develop sensitive, simple, highly selective, and cost-effective bioassay bioassays. Due to its high specificity, high sensitivity, excellent accuracy, and practicality, immunoassays are considered as one of the most widely used techniques for protein detection. So far, various methods and strategies based on the principle of different signal sensors have been reported and developed for this purpose. In general, colorimetric immunoassay is the most commonly used method in immunoassays because of several important advantages:

CIA Based Kits Development

  • Simplicity
  • Practicality
  • Low cost
  • Rapid/direct readout with the naked eye

The growing need for screening diseases at an early stage of development requires ultra-sensitive detection of biologically relevant species at extremely low levels of expression. To keep pace with expectations in clinical immunoassays, Creative Biolabs is developing highly sensitive, more flexible, quantitative, and easy-to-use colorimetric immunoassay-based kits to meet our customers’ needs.

Our Colorimetric Immunoassay Platforms

Creative Biolabs has been devoted for the development of enzyme-based colorimetric immunoassays by using native enzyme labels as the signal amplification strategies, e.g. horseradish peroxidase (HRP), alkaline phosphatase (ALP) and β-galactosidase, due to their high catalytic activity, high specificity, mild reaction conditions, and easy conjugation to antibodies. Moreover, a single enzyme molecule can also catalytically transform many molecules of substrate into a product.

Creative Biolabs increases the sensitivity of enzyme-based colorimetric immunoassays by enhancing the ratio between enzyme molecule and target analyte.

  • Utilizing the molecular biology techniques, e.g. by using polymerized enzymes, enzyme-anti-enzyme complexes, liposome-entrapped enzymes, and the biotin-avidin conjugate chemistry.
  • Employing nanomaterials as the carriers of enzymes and detection antibodies.
  • Develop innovative and powerful novel molecular biology methods by coupling with highly efficient Nano catalytic techniques, controlling and tailoring their properties in a very predictable manner to meet the needs of specific applications.

To assist customers for specific detection of proteins, Creative Biolabs offers a wide range of assay kits. Coupled with our analyzers, a bespoke solution for users at every level is available, from the smallest analytical facilities to high throughput analytical laboratories.
