Isotype

Mouse IgG2b

Specificity

The mouse monoclonal antibody DBN-N-03 recognizes drebrin, an approximately 100-125 kDa intracellular regulator of actin cytoskeleton.

Application

FC (QC tested)

Application details

Flow cytometry: The reagent is designed for analysis of human blood cells using 4 μl reagent / 100 μl of whole blood or 10⁶ cells in a suspension. The content of a vial (0.4 ml) is sufficient for 100 tests. Intracellular staining.

Reactivity

Human

Immunogen

Bacterially expressed N-terminal fragment of recombinant human drebrin (aa 1-326)

Preparation

Purified antibody is conjugated with R-phycoerythrin (PE) under optimum conditions. Unconjugated antibody and free fluorochrome are removed by size-exclusion chromatography.

Formulation

Stabilizing phosphate buffered saline (PBS), pH 7.4, 15 mM sodium azide

Storage and handling

Store at 2-8°C. Protect from prolonged exposure to light. Do not freeze.

Antigen description

Drebrin is an actin-binding protein, which is expressed mainly in neurons and plays important role in their morphogenesis. The highest level of its expression is in developing brain. Both in neurons and non-neuronal cells drebrin acts as a key regulator of actin cytoskeleton remodelling, affecting especially intercellular junctions, such as dendritic spines of neurons or the immune synapses of T cells. Decrease of drebrin amount in the brain seems to be associated with Alzheimer's disease and Down syndrome, and in case of B-cell precursor acute lymphoblastic leukemia (BCP-ALL) lower drebrin expression correlates with higher risk of relapse.

Separation of REH cells stained using anti-human Drebrin (DBN-N-03) PE antibody (10 μl reagent per million cells in 100 μl of cell suspension, red-filled) from REH cells stained using mouse IgG1 isotype control (MOPC-21) PE antibody (concentration in sample 5 μg/ml, same as Drebrin PE concentration, black-dashed) in flow cytometry analysis (intracellular staining) of REH cell suspension.
