The Human IL5 (Interleukin-5) ELISA Kit is specifically designed for the accurate measurement of IL5 levels in human serum, plasma, and cell culture supernatants. With its high sensitivity and specificity, this kit ensures reliable and reproducible results, making it an essential tool for a wide range of research applications. IL5 is a key cytokine that plays a crucial role in the regulation of immune responses, particularly in the development and differentiation of eosinophils. Abnormal levels of IL5 have been implicated in various inflammatory and allergic conditions, making it a valuable biomarker for studying these diseases and potential therapeutic interventions.
This ELISA kit provides researchers with a comprehensive and efficient method for the quantitative assessment of IL5 levels, allowing for detailed analysis and exploration of its role in immune regulation and disease pathogenesis. Trust in the Human IL5 ELISA Kit for robust and accurate measurements in your research endeavors.

Note:The below protocol is a sample protocol. Protocols are specific to each batch/lot. For the correct instructions please follow the protocol included in your kit.
Step
Procedure
1
Reagent & Plate Preparation: Equilibrate reagents and TMB substrate to room temperature. Set standard, test sample and control (zero) wells on the pre-coated plate and record their positions.
2
Primary Incubation: Prepare standards, samples, blanks and load into designated wells. Incubate plate at 37°C for 90 minutes to allow antigen binding.
3
Detection Antibody Binding: Add biotin-labeled detection antibody and incubate at 37°C for 60 minutes.
4
HRP-Streptavidin Binding: Add HRP-Streptavidin (SABC) and incubate at 37°C for 30 minutes.
5
Color Development: Add TMB substrate and incubate in the dark for 10–20 minutes.
6
Stop Reaction & Reading: Add stop solution and measure absorbance at 450 nm immediately.
Sample Type
Protocol
Serum
Allow blood to clot, centrifuge at 1000 × g for 20 minutes, collect supernatant supernatant and store appropriately.
Plasma
Collect using anticoagulant tubes, centrifuge at 1000 × g for 15 minutes at 2–8°C and collect plasma.
Tissue Homogenate
