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. Human fetal liver lysate, A549 cell lysate, Human lipoma tissue, Human thyroid carcinoma tissue.
