The Porcine FGF19 (Fibroblast Growth Factor 19) ELISA Kit is a highly sensitive and specific assay designed for the accurate quantification of FGF19 levels in porcine serum, plasma, and cell culture supernatants. This kit provides dependable and reproducible results, making it suitable for a wide range of research applications. FGF19 is a key growth factor that plays a crucial role in various biological processes, including cell proliferation, differentiation, and metabolism regulation. It is particularly important in the liver as it regulates bile acid synthesis and glucose metabolism.
Abnormal FGF19 levels have been implicated in liver diseases, metabolic disorders, and certain cancers, making it a valuable biomarker for studying these conditions and developing potential treatments. This ELISA kit offers researchers a reliable tool for studying the role of FGF19 in physiological and pathological processes, allowing for accurate measurement of FGF19 levels and facilitating further investigation into its mechanisms of action.

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.
