    NogoΔ20-induced Rho activation depends on internalization. (A–C) Rho activation levels were examined in PC12 cells that were either untreated (control; A), treated with 300 nM NogoΔ20 for 30 min at 37°C in absence of mutant PincherG68E (B), or treated with 300 nm NogoΔ20 treated for 30 min at 37°C in the presence of mutant PincherG68E (C). Active GTP-bound Rho was detected by incubation with GST-tagged Rhotekin-RBD and immunostaining using ab19256. Bar, 20 µm. (D) Densitometric quantification of staining from three independent experiments. Data are normalized to the mean of the untreated group ± SEM (error bars); asterisks marks highly significant differences between untreated, NogoΔ20-treated, or NogoΔ20- and dn PincherG68E-treated cells (three experiments; 30–50 cells per experiment; ***, P < 0.001; Student’s t test). (E) PC12 cells were either left untreated or transfected with dn PincherG68E construct. All cells were then incubated with 300 nM NogoΔ20 for 30 min at 37°C. Extracted

Inquiry: 1. Will this antibody recognize GST dimer? 2. I have a GST fused to the c-terminal of my protein expressed in Hela cells. I use 1:1000 dilution. I can see the band expressed from E.coli (using pET3a constructs), but not from Hela (pcDNA5,...

Thank you for contacting us.
The ability for an antibody to recognize an epitope tag can be dependent on the recombinant protein and expression system. We do not have experience using this antibody to detect GST dimer. As shown in the datasheet, t...
