Cultures were treated for 4 h with either 50 ng/ml BDNF or 2 μM <t>TTX</t> in the presence of 4 mM AHA and processed for 'click reaction' with a TAMRA-alkyne tag in the FUNCAT procedure.

BSA (1000 pg/lane) was used as a negative control. The mouse monoclonal anti-BDNF antibody, (1:1000; Sigma) was tested as a control. ( B ) Central region of the same blot shown in A, from an overexposed film to better visualize the reactivity against pro-BDNF. ( C ) Reactivity of antibodies from Biosensis, Promega-Emax ® pAb and Sigma on a dot blot in which the same quantity of pro-BNDF and mature BDNF were spotted (100 pg each).

    Line-blot for qualitative analysis of anti-BDNF antibodies specificity. ( A ) The antibodies from each ELISA kit were tested for specificity against pro-BDNF or mature BDNF. The BDNF standards blotted were commercial pro-BDNF (Alomone; 10 pg/lane), mature BDNF (1 and 2 from Alomone and Sigma, respectively; both 1000 pg/lane) and the standard BDNF protein included in each kit (Aviscera-Bioscience and Biosensis: 10 pg/lane; Millipore-ChemiKine TM , Millipore-Milliplex ® - and R D System-Quantikine ® : 100 pg/lane; Promega-Emax ® : 1000 pg/lane). BSA (1000 pg/lane) was used as a negative control. The mouse monoclonal anti-BDNF antibody, (1:1000; Sigma) was tested as a control. ( B ) Central region of the same blot shown in A, from an overexposed film to better visualize the reactivity against pro-BDNF. ( C ) Reactivity of antibodies from Biosensis, Promega-Emax ® pAb and Sigma on a dot blot in which the same quantity of pro-BNDF and mature BDNF were spotted (100 pg each). Each antibody from the ELISA kits was used at the dilution suggested by the manufacturer’s instructions. mAb: Promega-Emax ® monoclonal capture antibody for plate coating. pAb: Promega-Emax ® polyclonal detection antibody.

    Article Snippet: Our findings suggest that MMP-9 plays a role in kindling development by converting pro-BDNF to mature BDNF in the hippocampus, whereas other factors mediate BDNF maturation during the later kindling stage.

    Structural plasticity induced by nicotine in mesencephalic DA neurons from wild-type (WT) mice and α6 or α4/α6 nAChR subunit null mutant mice. Morphological effects of nicotine on DA neurons from (A–C) α6KO and WT mice and (D–F) α4/α6KO and WT mice on maximal dendrite length (A,D) , number of primary dendrites (B,E) and soma area (C,F) measured 72 h after exposure to nicotine (10 μM), or BDNF (10 ng/ml) here used as active control group. Two-way ANOVA was used to analyze data in panels (A–C) and (D–F) , respectively. Data are expressed as mean ± SEM ( ∗∗∗ p
