Technical Data
DNER (Delta and Notch-like Epidermal Growth Factor-related Receptor, Brain EGF Repeat Containing Transmembrane Protein, BET)
DNER, also known as brain EGF repeat containing transmembrane protein (BET), is a neuron-specific type I transmembrane notch ligand that is expressed on membranes of dendrites and cell bodies but not axons. It contains ten extracellular EGF-like domains and one follistatin-like domain (between the 9th and 10th EGF-like domains). DNER mediates neuron-glia interactions and is required for the functional and morphological maturation of the cerebellum. The extracellular domains of human and mouse DNER share 89% amino acid sequence homology.

Western Blot: This antibody can be used at 0.1-0.2ug/ml with the appropriate secondary reagents to detect human DNER. The detection limit for rhDNER is approximately 1 ng/lane and 5 ng/lane under non-reducing and reducing conditions, respectively.
Flow Cytometry: This antibody has been tested on A172 human glioblastoma cells for use in flow cytometry. Dilute this antibody to 50ug/ml and add 10 L of the diluted solution to 1-2.5 x 10e5 cells in a total reaction volume not exceeding 200 L. The binding of unlabeled antibodies may be visualized by adding 10 L of a 25ug/ml stock solution of a secondary developing reagent such as anti-goat lgG conjugated to a fluorochrome.
Immunocytochemistry: This antibody has been used at a concentration of 10ug/ml to detect DNER in A172 human glioblastoma cells. Cells were fixed with PBS containing 4% paraformaldehyde for 20 minutes at room temperature and blocked with PBS containing 10% normal donkey serum, 0.1% Triton X-100, and 1% BSA for 45 minutes at room temperature. After blocking, cells were incubated with diluted primary antibody overnight at 4 C followed by Rhodamine RedTM-coupled anti-goat IgG at room temperature in the dark for one hour. Between each step, cells were washed with PBS containing 0.1% BSA.
Direct ELISA: This antibody can be used at 0.5-1.0ug/ml with the appropriate secondary reagents to detect human DNER. The detection limit for rhDNER is approximately 0.2 ng/well.
Optimal dilutions should be determined by each laboratory for each application.

Storage and Stability:
Lyophilized powder may be stored at 4C for short-term only. Reconstitute to nominal volume by adding sterile PBS with 40-50% glycerol and store at -20C. Reconstituted product is stable for 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
