Product overview
Human BDNF ELISA Kit (ab212166) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of BDNF protein in cell culture supernatant, serum, cit plasma, edta plasma, and hep plasma. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human BDNF with 2.4 pg/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.
SPECIES REACTIVITY
This kit recognizes human BDNF protein and is cross-reactive to mouse and rat BDNF protein.
ASSAY SPECIFICITY
This kit recognizes both native and recombinant human BDNF protein in serum, plasma, and cell culture supernatant samples only.
Cell and tissue extract samples have not been tested with this kit.
CROSS REACTIVITY
Recombinant TRKB was prepared at 50 ng/mL and 500 pg/mL and assayed for cross reactivity. No cross-reactivity was observed.
INTERFERENCE
Recombinant TRKB was prepared at 50 ng/mL and 1 ng/mL and tested for interference with human BDNF at 200 pg/mL. 39% Inference was observed with 1ng/mL and 76% Interference was observed with 50 ng/mL.

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.

Function
During development, promotes the survival and differentiation of selected neuronal populations of the peripheral and central nervous systems. Participates in axonal growth, pathfinding and in the modulation of dendritic growth and morphology. Major regulator of synaptic transmission and plasticity at adult synapses in many regions of the CNS. The versatility of BDNF is emphasized by its contribution to a range of adaptive neuronal responses including long-term potentiation (LTP), long-term depression (LTD), certain forms of short-term synaptic plasticity, as well as homeostatic regulation of intrinsic neuronal excitability. -
Tissue specificity
Brain. Highly expressed in hippocampus, amygdala, cerebral cortex and cerebellum. Also expressed in heart, lung, skeletal muscle, testis, prostate and placenta. -
Involvement in disease
Bulimia nervosa 2
Congenital central hypoventilation syndrome -
Sequence similarities
Belongs to the NGF-beta family. -

Interpolated concentrations of native BDNF in human serum, and plasma samplesThe 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).

Serum from ten individual healthy human male and female donors was measured in duplicate.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.

Interpolated concentrations of native BDNF in rat serum sample.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.

Comparison of secreted BDNF in unstimulated and PMA/PHA-stimulated L929 Cells.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.

Linearity of dilution in Sample Diluent NS.Linearity of dilution is determined based on interpolated values from the standard curve. Linearity of dilution defines a sample concentration interval in which interpolated target concentrations are directly proportional to sample dilution.
Native BDNF was measured in the following biological samples in a 2-fold dilution series. Sample dilutions are made in Sample Diluent NS.
