The Rat T4 ELISA Kit is specifically designed for the precise measurement of thyroxine (T4) levels in rat serum, plasma, and tissue extracts. This advanced kit offers exceptional sensitivity and accuracy, guaranteeing consistent and dependable results for a variety of research purposes. Thyroxine (T4) is a critical thyroid hormone that regulates metabolism, growth, and development in the body. Fluctuations in T4 levels are associated with thyroid disorders, metabolic conditions, and hormonal imbalances, making it a crucial biomarker for studying these conditions and monitoring treatment outcomes.
Whether you are conducting basic research, preclinical studies, or clinical trials, the Rat T4 ELISA Kit provides the reliable data you need to advance your understanding of thyroid function and related health conditions. Trust in this kit to deliver precise and reproducible results, ensuring the success of your experiments and investigations.

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 TMB substrate for 30 minutes at room temperature. Prepare standards, samples (minimum 1:2 dilution), blanks, assign wells, and pre-wash the plate twice.
2
Sample & Biotin-Antibody Binding: Add 50 µL standard or sample followed by 50 µL biotin-labeled antibody to each well. Mix gently and incubate at 37°C for 45 minutes.
3
Washing: Wash the plate 5 times with wash buffer, allowing 1 minute soak time per wash.
4
Color Development: Add TMB substrate and incubate in the dark at 37°C for 10-20 minutes until color develops.
5
Stop Reaction: Add stop solution to terminate the reaction. The color changes from blue to yellow immediately.
6
Reading: Measure absorbance at 450 nm using a microplate reader.
Sample Type
Protocol
Serum
Allow blood to clot, centrifuge at 1000 × g for 20 minutes, collect supernatant and store appropriately.
Plasma
Collect using EDTA anticoagulant, centrifuge at 1000 × g for 15 minutes at 2–8°C and collect plasma.
Cell Culture Supernatant
Centrifuge at 1000 × g for 20 minutes at 4°C and collect clarified supernatant.
Cell Lysate
