Product overview
FGF-21 in vitro CatchPoint® SimpleStep ELISA® (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of FGF-21 protein in mouse serum, plasma, and cell culture supernatants.
This CatchPoint SimpleStep ELISA kit has been optimized for Molecular Devices Microplate Readers. Click here for a list of recommended Microplate Readers.
If using a Molecular Devices’ plate reader supported by SoftMax® Pro software, a preconfigured protocol for these CatchPoint SimpleStep ELISA Kits is available with all the protocol and analysis settings at www.softmaxpro.org
The CatchPoint SimpleStep ELISA employs an affinity tag labeled capture antibody and a reporter conjugated detector antibody which immunocapture the sample analyte in solution. This entire complex (capture antibody/analyte/detector antibody) is in turn immobilized via immunoaffinity of an anti-tag antibody coating the well. To perform the assay, samples or standards are added to the wells, followed by the antibody mix. After incubation, the wells are washed to remove unbound material. CatchPoint HRP Development Solution containing the Stoplight Red Substrate is added. During incubation, the substrate is catalyzed by HRP generating a fluorescent product. Signal is generated proportionally to the amount of bound analyte and the intensity is measured in a fluorescence plater reader at 530/570/590 nm Excitation/Cutoff/Emission.
Rat serum and plasma samples are not compatible with this kit.

Notes
FGF-21 is a secreted protein, a member of a large FGF gene family. FGF-21 stimulates glucose uptake in differentiated adipocytes via the induction of glucose transporter SLC2A1/GLUT1 expression but not via SLC2A4/GLUT4 expression. FGF-21 activity probably requires the presence of KLB.

Other - Mouse FGF-21 ELISA Kit, Fluorescent (ab229382)SimpleStep ELISA technology allows the formation of the antibody-antigen complex in one single step, reducing assay time to 90 minutes. Add samples or standards and antibody mix to wells all at once, incubate, wash, and add your final substrate. See protocol for a detailed step-by-step guide.

Example of mouse FGF-21 standard curve in Sample Diluent NSBackground-subtracted data values (mean +/- SD) are graphed.
-
Interpolated concentrations of native FGF-21 in mouse serum and plasma samplesThe concentrations of FGF-21 were measured in duplicates, interpolated from the FGF-21 standard curves and corrected for sample dilution. Undiluted samples are as follows: serum 100%, plasma (citrate) 100%, plasma (EDTA) 100%, and plasma (heparin) 50%. The interpolated dilution factor (to neat sample) corrected values are plotted (mean +/- SD, n=2). The mean FGF-21 concentration was determined to be 409 pg/mL in neat serum, 397 pg/mL in neat plasma (citrate), 358 pg/mL in neat plasma (EDTA), and 348 pg/mL in neat plasma (heparin).

Interpolated concentrations of native FGF-21 in untreated L-929 cell culture supernatant samplesThe concentrations of FGF-21 were measured in duplicates, interpolated from the FGF-21 standard curves and corrected for sample dilution. Undiluted samples are as follows: L-929 cell culture supernatant 100%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean FGF-21 concentration was determined to be 59 pg/mL in neat L-929 cell culture supernatant.

Interpolated concentrations of FGF-21 in normal female CD-1 mouse serum and pregnant female CD-1 mouse serum at day 18 of gestationThe concentrations of FGF-21 were measured in three different dilutions in duplicate and interpolated from the FGF-21 standard curve and corrected for sample dilution. The interpolated dilution factor corrected values are plotted in pg FGF-21 per mL of neat serum (mean +/- SD, n=3). FGF-21 concentration was determined to be 401 pg/mg in normal mouse serum, and 9,193 pg/mL in pregnant mouse serum.
