Overview

  • Product name

    Anti-FGF21 antibody [EPR8314(2)]
    See all FGF21 primary antibodies

  • Description

    Rabbit monoclonal [EPR8314(2)] to FGF21

  • Host species

    Rabbit

  • Specificity

    The immunogen used for this product shares 6 continuous identical amino acids with SIKE1. Cross-reactivity with this protein has not been confirmed experimentally.

    Expression levels of the target protein vary with sample type and some optimisation may be required (PMID: 27285327).  For western blot using cell lines, it may be necessary to collect cell culture supernatant for endogenous FGF21 detection as the target protein is readily secreted (PMID: 24041694; PMID: 26691139).

  • Tested applications

    Suitable for: WB, IHC-Pmore details
    Unsuitable for: ICC/IF

  • Species reactivity

    Reacts with: Mouse, Rat, Human

  • Immunogen

    Synthetic peptide within Human FGF21 aa 1-100. The exact sequence is proprietary.
    Database link: Q9NSA1

  • Positive control

    • Recombinant human FGF21 + IgG1 fusion protein (Fc Chimera Active) (ab108556) can be used as a positive control in WB. WB: Human fetal liver lysate, mouse spleen, rat spleen. IHC-P: Human stomach

      Immunohistochemical staining of paraffin embedded human stomach with purified ab171941 at a working dilution of 1/250. The secondary antibody used is ab97051, a HRP-conjugated goat anti-rabbit IgG (H+L), at a dilution of 1/500. The sample is counter-stained with hematoxylin. Antigen retrieval was perfomed using Tris-EDTA buffer, pH 9.0. PBS was used instead of the primary antibody as the negative control, and is shown in the inset.
