Description

Rat ECF/CCL11 (Eosinophil Chemotactic Factor) ELISA Kit

The Rat ECF/CCL11 (Eosinophil Chemotactic Factor) ELISA Kit is a specialized assay designed for the quantitative detection of Eosinophil Chemotactic Factor, also known as CCL11, in various rat biological samples. Eosinophil Chemotactic Factor (ECF/CCL11) is a chemokine that plays a crucial role in the chemotaxis and activation of eosinophils, a type of white blood cell involved in immune responses and allergic reactions. Accurate measurement of ECF/CCL11 levels using this ELISA kit can provide valuable insights into the role of eosinophils in immune responses, inflammation, and allergic diseases.

Dysregulation of ECF/CCL11 has been implicated in various inflammatory conditions and respiratory disorders, making it an important target for research in immunology and allergy-related studies. The Rat ECF/CCL11 ELISA Kit from Assay Genie offers exceptional sensitivity and specificity, ensuring accurate and reproducible results. Manufactured under stringent quality control standards, this kit provides reliable performance, ease of use, and robust analytical data, making it a valuable tool for research investigations related to eosinophil biology and immune response modulation.

Specificity:This kit recognizes Rat ECF/CCL11 in samples. No significant cross-reactivity or interference between Rat ECF/CCL11 and analogues was observed.
Reproducibility:Both intra-CV and inter-CV are < 10%.
Application:This ELISA kit applies to the in vitro quantitative determination of Rat ECF/CCL11 concentrations in Serum, plasma and other biological fluids.

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Rat ECF/CCL11. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Rat ECF/CCL11 and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Rat ECF/CCL11, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Rat ECF/CCL11. You can calculate the concentration of Rat ECF/CCL11 in the samples by comparing the OD of the samples to the standard curve.

Precision

Intra-assay Precision (Precision within an assay): 3 samples with low, mid range and high level Rat ECF/CCL11 were tested 20 times on one plate, respectively.

Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level Rat ECF/CCL11 were tested on 3 different plates, 20 replicates in each plate.
