The Human FGF21 ELISA Kit is a powerful tool for the precise measurement of FGF21 levels in human biological samples such as serum, plasma, and cell culture supernatants. With outstanding sensitivity and specificity, this kit delivers consistent and accurate results, making it an excellent choice for various research purposes. FGF21, also known as fibroblast growth factor 21, is a key player in metabolic regulation, energy balance, and insulin sensitivity. Dysregulation of FGF21 has been associated with metabolic disorders such as obesity, diabetes, and fatty liver disease, making it a valuable biomarker for exploring these conditions and potential therapeutic interventions.
By utilizing the Human FGF21 ELISA Kit, researchers can gain valuable insights into the role of FGF21 in disease pathogenesis and progression, paving the way for the development of novel treatment strategies. Trust in the reliability and precision of this kit to advance your research in the field of metabolic health and beyond.

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
