A. W21139F_PURE_DBN1_WB_021624
Whole cell extracts (15 µg total protein per lane) from the indicated cell lines were resolved on a 4-12% Bis-Tris gel, transferred to a PVDF membrane, and probed with 1 µg/mL of Purified anti-DBN1 (clone W21139F) overnight at 4°C. Proteins were visualized by chemiluminescence detection using HRP Goat anti-rat IgG (Cat. No. 405405) at a 1:5000 dilution. Direct-Blot™ HRP anti-β-actin (Cat. No. 664804) was used as a loading control at a 1:25000 dilution. Western-Ready™ ECL Substrate Premium Kit (Cat. No. 426319) was used as a detection agent. Lane M: Molecular weight marker

    HeLa cells without (panels A and B) or with DBN1 knockdown (panels C and D) were fixed with ice-cold methanol, and then blocked with 5% FBS for 1 hour at room temperature. Cells were then intracellularly stained with 5 µg/mL of Purified anti-DBN1 (clone W21139F), followed by incubation with 2.5 µg/mL of Alexa Fluor® 594 Goat anti-rat IgG (Cat. No. 405422) for 1 hour at room temperature. Nuclei were counterstained with DAPI (Cat. No. 422801) (blue, panels B and D). The image was captured with a 40X objective. Scale bar: 25 µm

Description

Drebrin (DBN1) is an actin-binding protein that was identified as a developmentally regulated protein expressed in the brain. Drebrin interacts with microtubules and is localized to focal adhesions, adherens junctions, gap junctions, immunological synapses, and neuronal synapses to modulate cellular processes such as cell migration, cell process formation, cancer metastasis, and spermatogenesis. There are two isoforms of mammals as a result of alternative splicing: Drebrin A (adult) and Drebrin E (embryonic). The expression of Drebrin A is highly specific to neurons and regulates the reorganization of actin filaments and thus contributes to memory, whereas Drebrin E is expressed in various tissues. Studies have shown that a decrease in the amount of Drebrin protein in the brain is thought to be a factor contributing to the pathogenesis of dementia in Alzheimer's disease (AD), Down syndrome (DS), and bipolar disorder (BD).

Recommended Usage

Each lot of this antibody is quality control tested by western blotting. For western blotting, the suggested use of this reagent is 0.125 - 1.0 µg/mL. For immunocytochemistry, a concentration range of 1.0 - 5.0 μg/mL is recommended. For flow cytometric staining, the suggested use of this reagent is ≤ 0.06 µg per million cells in 100 µL volume. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

The clone does not cross-react with mouse in western blotting (WB).

For immunocytochemistry (ICC), we recommend to use 4% PFA fixation followed by permeabilization with 0.5% Triton X-100 or ice cold-methanol, or ice-cold methanol fixation.

For intracellular flow cytometry (ICFC), the recommended dosage is 0.06 μg per test using Fixation Buffer (Cat. No. 420801) followed by True-Phos™ Perm Buffer (Cat No. 425401), or Intracellular Staining Permeabilization Wash Buffer (Cat No. 421002), or using Cyto-Fast™ Fix/Perm Buffer Set (Cat. No. 426803) and True-Nuclear™ Transcription Factor Buffer Set (Cat. No. 424401).

This product is not recommended for use in immunohistochemistry (IHC).

Additional Product Notes

This antibody has been tested in knockout/knockdown models for ICC.
