ELISA kit development is based on the specific binding reaction between antigen and antibody. The antigen or antibody is fixed on a solid phase carrier (such as a microplate), and the detection is carried out using an enzyme-labeled antibody or antigen. Finally, the concentration of the target substance is quantitatively analyzed through a color reaction (such as the substrate is catalyzed by the enzyme to generate a colored product). Its core advantages lie in high sensitivity, high specificity, and repeatability of the operation process. ELISA testing is widely used in disease detection, biomarker analysis, drug screening, food safety, environmental monitoring and other fields. Creative Diagnostics has extensive expertise in ELISA kit development and has original ELISA kit development solutions to support the development of ELISA kits. With our extensive experience in ELISA kit development, we provide highly sensitive and accurate ELISA kit development methods to meet various needs from research tools to industrial production.
The common ELISA kit is usually composed of pre-coated microplates, enzyme-labeled secondary antibodies, standards, colorimetric substrates (TMB), stop solutions, diluents and washing solutions. ELISA kits can be divided into different types according to different detection methods, such as sandwich methods, indirect methods, competitive methods, etc.
So far, ELISA kits are used in scientific research, clinical diagnosis, food safety testing, environmental monitoring, and vaccine development. A kits with good performance, high sensitivity and good repeatability can not only improve the experimental efficiency, but also have important significance for the accuracy and reliability of data. With the advancement of technology, the development of automated, high-throughput ELISA platforms is also constantly promoting the development of this field.

Creative Diagnostics conducted intra- and inter-assay precision analysis on the ELISA kits it developed. The figure shows the repeatability of the ELISA kits at three concentration levels (Low, Medium, High) in the form of a bar chart, including: Intra-assay Precision: The coefficient of variation (CV%) of multiple test results of the same kit batch under the same experimental conditions, represented by a blue bar. Inter-assay Precision: The test variability of different batches of kits at different experimental times, represented by a green bar. The results showed that both within and between groups, CV% was much lower than the 10% usually set by the industry standard, indicating that the kit has good consistency at different times, batches and experimenters.
