Product overview
Human Doublecortin ELISA Kit (ab218267) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Doublecortin protein in tissue extracts and cell culture extracts. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human Doublecortin with 2.13 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.

Notes
Doublecortin is a microtubule-associated protein required for initial steps of neuronal dispersion and cortex lamination during cerebral cortex development. It may act by competing with the putative neuronal protein kinase DCLK1 in binding to a target protein. Doublecortin may in that way participate in a signaling pathway that is crucial for neuronal interaction before and during migration, possibly as part of a calcium ion-dependent signal transduction pathway. Doublecortin may be part with PAFAH1B1/LIS-1 of overlapping, but distinct, signaling pathways that promote neuronal migration. Doublecortin interacts with tubulin and USP9X.
Mutations affecting the Doublecortin gene are causing X-linked 1 Lissencephaly, a disease characterized by mental retardation and seizures that are more severe in male patients. Female patients display a less severe phenotype referred to as 'doublecortex'.
Doublecortin is highly expressed in neuronal cells of fetal brain (in the majority of cells of the cortical plate, intermediate zone and ventricular zone), but not expressed in other fetal tissues. In the adult, it is highly expressed in the brain frontal lobe, but it has very low expression in other regions of brain, and it is not detected in heart, placenta, lung, liver, skeletal muscles, kidney and pancreas.

Function
Seems to be required for initial steps of neuronal dispersion and cortex lamination during cerebral cortex development. May act by competing with the putative neuronal protein kinase DCAMKL1 in binding to a target protein. May in that way participate in a signaling pathway that is crucial for neuronal interaction before and during migration, possibly as part of a calcium ion-dependent signal transduction pathway. May be part with LIS-1 of an overlapping, but distinct, signaling pathways that promote neuronal migration. -
Tissue specificity
Highly expressed in neuronal cells of fetal brain (in the majority of cells of the cortical plate, intermediate zone and ventricular zone), but not expressed in other fetal tissues. In the adult, highly expressed in the brain frontal lobe, but very low expression in other regions of brain, and not detected in heart, placenta, lung, liver, skeletal muscles, kidney and pancreas. -
Involvement in disease
Defects in DCX are the cause of lissencephaly X-linked type 1 (LISX1) [MIM:300067]; also called X-LIS or LIS. LISX1 is a classic lissencephaly characterized by mental retardation and seizures that are more severe in male patients. Affected boys show an abnormally thick cortex with absent or severely reduced gyri. Clinical manifestations include feeding problems, abnormal muscular tone, seizures and severe to profound psychomotor retardation. Female patients display a less severe phenotype referred to as 'doublecortex'.
Defects in DCX are the cause of subcortical band heterotopia X-linked (SBHX) [MIM:300067]; also known as double cortex or subcortical laminar heterotopia (SCLH). SBHX is a mild brain malformation of the lissencephaly spectrum. It is characterized by bilateral and symmetric plates or bands of gray matter found in the central white matter between the cortex and cerebral ventricles, cerebral convolutions usually appearing normal.
Note=A chromosomal aberration involving DCX is found in lissencephaly. Translocation t(X;2)(q22.3;p25.1). -

Interpolated concentrations of native Doublecortin in SH-SY5Y cell extract, human fetal brain tissue extract and rat brain tissue extract.Interpolated concentrations of native Doublecortin in SH-SY5Y cell extract samples based on a 100 µg/mL extract load, human fetal brain tissue extract samples based on a 300 µg/mL extract load, and rat brain tissue extract samples based on a 500 µg/mL extract load. The concentrations of Doublecortin were measured in duplicate and interpolated from the Doublecortin standard curve and corrected for sample dilution. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean Doublecortin concentration was determined to be 703 pg/mL in SH-SY5Y cell extract samples, 415 pg/mL in human fetal brain tissue extract samples, and 535 pg/mL in rat brain tissue extract samples.
