  • Product overview

    Abcam’s FGF9 Human ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human FGF9 in plasma and cell culture supernatants. (Human FGF9 concentration is pretty low in normal plasma, it may not be detected in this assay).

    This assay employs an antibody specific for Human FGF9 coated on a 96-well plate. Standards and samples are pipetted into the wells and FGF9 present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human FGF9 antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of FGF9 bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

    We have not been able to detect the endogenous Human FGF9 in normal serum with ab100520, only in serum spiked with Human FGF9.

  • Research areas
  • Function
    Plays an important role in the regulation of embryonic development, cell proliferation, cell differentiation and cell migration. May have a role in glial cell growth and differentiation during development, gliosis during repair and regeneration of brain tissue after damage, differentiation and survival of neuronal cells, and growth stimulation of glial tumors.
  • Tissue specificity
    Glial cells.
  • Involvement in disease
    Defects in FGF9 are the cause of multiple synostoses syndrome type 3 (SYNS3) [MIM:612961]. Multiple synostoses syndrome is an autosomal dominant condition characterized by progressive joint fusions of the fingers, wrists, ankles and cervical spine, characteristic facies and progressive conductive deafness.
  • Sequence similarities
    Belongs to the heparin-binding growth factors family.
  • Post-translational
    Three molecular species were found (30 kDa, 29 kDa and 25 kDa), cleaved at Leu-4, Val-13 and Ser-34 respectively. The smaller ones might be products of proteolytic digestion. Furthermore, there may be a functional signal sequence in the 30 kDa species which is uncleavable in the secretion step.

Thank you for your reply. The microplate is from Greiner, cat# 762071. This should allow you to find any specific dimension information needed. Please let me know if you have any further questions.

Thank you for contacting us.

These kits are provided with 12 strips of 8 wells each in a frame that is the same size as a standard 96-well plate (˜5 x 3.33"). If you need any more specific information, please let me know and I will be happy t...

Thank you for contacting Abcam earlier today.

I have spoken to the lab and they have advised that you should not store the detection antibody concentrate for longer than 5 days at 4ºC. While not ideal, if you absolutely need to store it ...
