  • Product overview

    Human BDNF in vitro SimpleStep ELISA® (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of free BDNF in human serum, plasma and cell culture supernatant.


    The 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. TMB substrate is added and during incubation is catalyzed by HRP, generating blue coloration. This reaction is then stopped by addition of Stop Solution completing any color change from blue to yellow. Signal is generated proportionally to the amount of bound analyte and the intensity is measured at 450 nm. Optionally, instead of the endpoint reading, development of TMB can be recorded kinetically at 600 nm.

  • Notes

    BDNF (Brain derived neurotrophic factor) is a member of the neurotrophin family of growth factors that includes nerve growth factor. BDNF is expressed as a proprotein that is cleaved to form mature BDNF (residues 129-247). This assay measures mature BDNF. Mature BDNF protein sequence is identical between human, mouse, rat and many additional species. BDNF binds to at least 2 receptors: TrkB and LNGFR.

  • ELISA Protocol Summary
  • Background-subtracted data values (mean +/- SD) are graphed.

  • The concentrations of BDNF were measured in duplicates, interpolated from the BDNF standard curves and corrected for sample dilution. Undiluted samples are as follows: serum 10%, plasma (citrate) 10%, plasma (EDTA) 10%, and plasma (heparin) 10%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean BDNF concentration was determined to be 954 pg/mL in serum, 2,189 pg/mL in plasma (citrate), 690 pg/mL in plasma (EDTA) and 856 pg/mL in plasma (heparin).

  • Interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean BDNF concentration was determined to be 1,176 pg/mL with a range of 653 – 2,387 pg/mL.

  • The concentrations of BDNF were measured in duplicates, interpolated from the BDNF standard curves and corrected for sample dilution. Undiluted samples are as follows: serum 10%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean BDNF concentration was determined to be 2,471 pg/mL in serum.

  • L929 cells were grown in the absence (unstimulated) or presence of Phorbol Myristate Acetate (PMA) and phytohemagglutinin (PHA) (stimulated) for 3 days. BDNF was measured in 2-fold diluted cell culture supernatants of unstimulated and PMA/PHA stimulated L929 and cell culture media. Measured values were interpolated from the BDNF Standard Curve diluted in Sample Diluent NS and corrected for dilution factor. Mean of duplicate values +/-SD are graphed: 2.3 pg/mL unstimulated, 50 pg/mL stimulated, and undetectable in media.

I have used the BDNF ELISA kit on proteins isolated from marmoset plasma(heparin). The samples were undiluted and diluted 1:2 and 1:4. I did not detect the BDNF in the sample of marmoset. However, I was able to detect in the same condition with the rat plasma. And, I tried to lengthen discrimination time, but was not able to detect in the plasma of the marmoset. I think that the BDNF ELISA kit ab212166 can not work for BDNF detection in marmoset sample.

I have used the BDNF elisa kit on proteins isolated from rat brain (hippocampus). In order to create the same conditions in both standard and samples i add 100 micro-liters of lysis buffer to the standard stock (lysis buffer- 200mM EDTA, 100mM tris,IGEPAL,Protease Inhibitor and Phosphatase Inhibitor in DDW). The samples were diluted 1:10 in order to minimize lysis buffer interference with the assay. The detection of BDNF in the samples was good as well as the standard curve which was accurate (despite the lysis buffer ). I think that the BDNF elisa kit ab212166 can defiantly work for BDNF detection in brain tissue lysats
