    Alomone Labs rabbit anti pro bdnf ab
    (A): RT-PCR of <t>BDNF,</t> its <t>high</t> <t>(TrkB)</t> and low (p75 NTR ) affinity receptors, TrkA, and TrkC from cells cultured in basal (10% FCS medium), WiDr (lane: 1), SW480 (lane: 2), SW620 (lane: 3), COLO 205 (lane: 4). GAPDH mRNA levels was used as an internal control. Positive control (lane 5) was the neuroblastoma cell line (IMR32) for BDNF, TrkB and p75 NTR ; and the erythromyeloblastoid leukemia cells (K562) for TrkA and C. A representative result of at least three to five independent experiments. (B) Comparison of TrkB95 and p75 NTR on total RNA extracted from WiDr cells cultured in 10% FCS or after 24 to 72 h serum deprivation (0% FCS). TrkB95 and p75 NTR mRNA/GAPDH mRNA quantification of band intensities evaluated by densitometry are shown above lanes and expressed in arbitrary units (mean of three independent experiments). (C) Same experiment: RT-PCR of TrkA and TrkC on total RNA extracted from WiDr cells cultured under basal culture conditions (10% FCS) and after 24–72 h of serum starvation in comparison to positive control (K562) (D) Expression of pro-BDNF and BDNF, full length TrkB 145 and truncated TrkB 95 and p75 NTR proteins in CRC cell lines cultured in 10% FCS. TrkA and TrkC were not detected. Actin was used as loading protein control. WiDr (lane: 1), SW480 (lane: 2), SW620 (lane: 3), COLO 205 (lane: 4). Positive control (lane: 5) were IMR32 cells for BDNF, pro-BDNF, TrkB and p75 NTR and K562 cells or TrkA and TrkC. A representative result of at least three independent experiments.

    Alomone Labs antibodies against pro bdnf
    Effects of the <t>anti-pro-BDNF</t> antibody on apoptosis, migration, and capillary-like-structure formation among MMECs after exposure to HG and H/R. (a) Effects of pro-BDNF on apoptosis were analyzed by flow cytometry of MMECs after different treatments: control, H/R, H/R + anti-pro-BDNF, and H/R + vehicle. (b, c) The functional effects of pro-BDNF on MMECs were assessed by capillary-like-structure formation and cell scratch assays. (d) Relative apoptosis levels and fold changes are expressed in relation to the control group. The H/R group showed markedly increased relative apoptosis levels, decreased capillary-like-structure formation, and reduced cell migration when compared with the control group. These effects were reversed by treatment with the anti-pro-BDNF antibody to the levels similar to those in the control group. The data were subjected to one-way ANOVA. The error bars represent SEM. ∗ P < 0.05 as compared with the control group; # P < 0.05 as compared with the H/R group or the H/R + vehicle group.

(a) Representative immunofluorescent images of pro-BDNF (red, first column), p-JNK (green, second column), BDNF (red, fourth column), JNK (green, fifth column), sortilin (red, seventh column), and p75 NTR (green, eighth column) in groups control, H/R, H/R + anti-pro-BDNF, and H/R + vehicle. (b–e) Representative Western blots and quantitative analysis of pro-BDNF, BDNF (b), p75 NTR , sortilin (c), JNK, p-JNK (d), caspase 3 and cleaved-caspase 3 expression (e) in response to different treatments. All the data were normalized to β -actin, and fold changes are expressed in relation to the control group. Exposure of MMECs to H/R resulted in significantly higher expression levels of pro-BDNF, p75 NTR , and sortilin and in activation of JNK and caspase 3 as compared with MMECs maintained under normal conditions (control). Nonetheless, there were no significant differences in BDNF, JNK, and caspase 3 expression levels after H/R. Treatment with the anti-pro-BDNF antibody significantly reversed the increase in the protein expression of pro-BDNF, p75 NTR , sortilin, p-JNK, and cleaved caspase 3 in MMECs after exposure to HG and H/R (H/R + anti-pro-BDNF). The data were subjected to one-way ANOVA. The error bars represent SEM. ∗ P < 0.05 as compared with the control group; # P < 0.05 as compared with the H/R or H/R + vehicle group.

    Effects of the anti-pro-BDNF antibody on apoptosis, migration, and capillary-like-structure formation among MMECs after exposure to HG and H/R. (a) Effects of pro-BDNF on apoptosis were analyzed by flow cytometry of MMECs after different treatments: control, H/R, H/R + anti-pro-BDNF, and H/R + vehicle. (b, c) The functional effects of pro-BDNF on MMECs were assessed by capillary-like-structure formation and cell scratch assays. (d) Relative apoptosis levels and fold changes are expressed in relation to the control group. The H/R group showed markedly increased relative apoptosis levels, decreased capillary-like-structure formation, and reduced cell migration when compared with the control group. These effects were reversed by treatment with the anti-pro-BDNF antibody to the levels similar to those in the control group. The data were subjected to one-way ANOVA. The error bars represent SEM. ∗ P < 0.05 as compared with the control group; # P < 0.05 as compared with the H/R group or the H/R + vehicle group.

    Article Snippet: Cells were fixed with 4% paraformaldehyde at room temperature (RT) for 30 min and permeabilized or not permeabilized with 0.5% Triton X-100 (Sigma-Aldrich), and nonspecific binding was blocked by incubation with 5% donkey serum (Jackson ImmunoResearch Laboratories) at RT for 30 min. Coverslips were incubated overnight at 4°C with the following primary antibodies: rabbit anti-BDNF (Abcam, 1 : 500), rabbit anti-pro-BDNF (Alomone Labs, 1 : 400), anti-JNK (Santa Cruz Biotechnology, 1 : 100), anti-phosphorylated-JNK (p-JNK) (Santa Cruz Biotechnology, 1 : 100), rabbit anti-p75 NTR (Santa Cruz Biotechnology, 1 : 100), and goat anti-sortilin (Abcam, 1 : 500) antibodies.

    Effects of the anti-pro-BDNF antibody on the expression of p75 NTR and sortilin and apoptosis-related proteins. (a) Representative immunofluorescent images of pro-BDNF (red, first column), p-JNK (green, second column), BDNF (red, fourth column), JNK (green, fifth column), sortilin (red, seventh column), and p75 NTR (green, eighth column) in groups control, H/R, H/R + anti-pro-BDNF, and H/R + vehicle. (b–e) Representative Western blots and quantitative analysis of pro-BDNF, BDNF (b), p75 NTR , sortilin (c), JNK, p-JNK (d), caspase 3 and cleaved-caspase 3 expression (e) in response to different treatments. All the data were normalized to β -actin, and fold changes are expressed in relation to the control group. Exposure of MMECs to H/R resulted in significantly higher expression levels of pro-BDNF, p75 NTR , and sortilin and in activation of JNK and caspase 3 as compared with MMECs maintained under normal conditions (control). Nonetheless, there were no significant differences in BDNF, JNK, and caspase 3 expression levels after H/R. Treatment with the anti-pro-BDNF antibody significantly reversed the increase in the protein expression of pro-BDNF, p75 NTR , sortilin, p-JNK, and cleaved caspase 3 in MMECs after exposure to HG and H/R (H/R + anti-pro-BDNF). The data were subjected to one-way ANOVA. The error bars represent SEM. ∗ P < 0.05 as compared with the control group; # P < 0.05 as compared with the H/R or H/R + vehicle group.
