Background
FGF-4 (Fibroblast Growth Factor-4), also known as FGF-K and K-FGF, is a secreted angiogenic factor that is mitogenic for fibroblasts and endothelial cells. During development, it is required for maintenance of the trophoectoderm and primitive endoderm, and it cooperates with FGF-8 in the apical ectodermal ridge. FGF-4 promotes embryonic stem cell proliferation and may also aid stem cell differentiation. A C-terminally truncated 15 kDa isoform that opposes full-length FGF-4 and promotes differentiation is endogenously expressed in human embryonic stem cells.

What is the difference between the Quantikine and Duoset ELISA kits?
Our Quantikine kits are fully optimized and validated for the sample types listed on the product specific webpage and datasheet, as this can vary between kits. Each kit is supplied ready to use with one pre-coated 96-well plate, a detection antibody directly conjugated to HRP, and all other necessary reagents. These kits are ideal for researchers who want the convenience of a ready to use and optimized ELISA product. Some of these kits are also available prepackaged in larger 6 and 50 plate sizes.Our DuoSet Kits, in contrast, are ELISA development kits containing the capture and detection antibody, the mass-value calibrated standard, and streptavidin-HRP to prepare approximately 5 or 15 plates. Ancillary reagents will need to be used/purchased, and for most kits, we will recommend one of our Ancillary Reagent Kits, which contain the reagents we use ourselves in-house. DuoSet kits are validated only for cell culture supernatant samples and therefore require further development and validation for accurate measurement in more complex samples such as serum and plasma. Our DuoSet Kits offer an economical, flexible alternative for the experienced ELISA user.
