Rabbit antibody to rhBDNF: affinity purified


Catalogue No. R-1707-100
Description BDNF belongs to the neurotrophin family and promotes the survival of neuronal populations that are all located either in the central nervous system or directly connected to it. It is a 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. The alterations in BDNF expression induced by various kinds of brain insult including stress, ischemia, seizure activity and hypoglycemia, may contribute to some pathologies such as depression, epilepsy, Alzheimer's, and Parkinson's disease. Microglia release BDNF that may contribute to neuroinflammation and neuropathic pain. SUBUNIT: Monomers and homodimers. Binds to NTRK2/TRKB. SUBCELLULAR LOCATION: Secreted protein. POst translation modification: Converted into mature BDNF by plasmin (PLG). SIMILARITY: Belongs to the NGF-beta family.
Batch No. See product label.
Unit size 100 ug
Antigen Antibody was raised against a GST-tagged rhBDNF fusion protein and expressed in and purified from E. coli.
Antibody Type Rabbit polyclonal.
Other Names Brain-derived neurotrophic factor; Abrineurin
Accession BDNF_HUMAN
Produced in Rabbit
Molecular Weight Mature BDNF dimer has a molecular weight of 28 kDa. In Western Blotting, mature BDNF monomer migrates at 14 kDa.
Purity Affinity purified on antigen column.
Applications Western Blotting (denaturing and reducing): 0.2 to 1 ug/mL. Antibody detects 14 kDa mature BDNF monomer and 32 kDa proBDNF monomer in cell lysate and tissue homonenate. Antibody has only been tested on cell lysate and tissue homogenate of human origin. Acid-treated samples may give cleaner blots, and enhance signals for BDNF. R-1707-100 is not recommended for human serum samples. For human serum analysis, we recommend mouse monoclonal antibody to rhBDNF (M-1744-50/100), or rabbit polyclonal antibody to BDNF peptide 1-10 (R-083-100, whole serum; R-066-500, IgG).

Flow Cytometry: ~2 ug per 10^6 cells, methanol fixation. Note: R-1707-100 cannot be used to distinguish the flow cytometry signal originating from mature BDNF versus proBDNF.

Biosensis recommends optimal dilutions/concentrations should be determined by the end user.
Specificity Human, rat and mouse BDNF. Expected to detect BDNF from other species due to sequence homology.
Cross-reactivity No cross-reactivity with other neurotrophins.

Form Lyophilized from a solution containing PBS pH 7.4, 3% trehalose, with 0.05% sodium azide.
Reconstitution Spin vial briefly before opening. Reconstitute vial with 100 uL sterile water to obtain a concentration of 1 mg/mL.
Storage Store lyophilized antibody at 2-8C protected from moisture. After reconstitution divide antibody into useful aliquots and keep aliquots at -20C to -80C for a higher stability. Working aliquots can be kept at 2-8C for up to 1 month. Avoid repetitive freeze/thaw cycles.
Expiry Date 12 months after purchase if unopened.

Rabbit antibody to rhBDNF: affinity purified Western blot analysis of BDNF expression in human SH-SY5Y cell lysates (A) and human brain (B). Polyclonal rhBDNF antibody R-1707-100 (1 µg/mL) detects monomeric BDNF at 14 kDa, and monomeric proBDNF at 32 kDa in lysates prepared either in RIPA buffer or in acid-extraction buffer (A). Control antibody M-1744-50/100 (1 µg/mL) confirms detection of mature BDNF (Lane 1) and proBDNF (Lane 2) using BDNF and proBDNF proteins. A second band at 18 kDa is observed in the proBDNF standard, likely to represent a proBDNF degradation product. In human brain (B), R-1707-100 detects mature BDNF (14 kDa) and proBDNF (32 kDa) in both preparations (Tris-buffer and acid-treated). Acid-treated brain demonstrates lower background staining and gives a stronger BDNF signal.

Western Blotting Method: SDS-PAGE: denaturing and reducing, 12% Bis-Tris gel; Transfer: Tris-Glycine buffer, semi-dry transfer; Membrane: nitrocellulose (0.22 µm); Blocking: 5% skim milk in TBST, 1 hour at RT; Primary antibody: overnight at 4°C; Secondary antibody: anti-mouse-HRP or anti-rabbit-HRP (1/6000), 2 hours at RT; Detection: Chemiluminiscence.
Rabbit antibody to rhBDNF: affinity purified Analysis of BDNF expression in rat C6 cells by Flow Cytometry. Fixing and permeabilization of cells: Absolute methanol (10 minutes in ice) and 0.1% Tween-20 in PBS, Blocking: 200 g/mL sheep IgG, Primary antibody: Rabbit polyclonal antibody to rhBDNF (cat # R-1707-100, 2 g per ~10^6 cells) for 30 minutes at room temperature, Secondary antibody: Goat anti-rabbit-PE labeled secondary antibody (1:100 dilution), 20 minutes in dark at room temperature. Negative control: Normal rabbit IgG. Data and results were generated using Orflo MoxiflowTM instrument and protocols.
