Santa Cruz Biotechnology plcβ1 probing

A NT2 cells progenitors were treated with RA and immunoblotted with anti-PLCβ1a and PLCβ1b antibodies at various times (48 h, 7 d, 14 d, 28 d). Terminally differentiated NT2N cells were isolated from cultures at 28 d of RA exposue by mechanical dislogding (see Methods). Equal amounts of total protein (12 μg) were loaded ( n = 4). B Similar studies as in ( A ) except NT2 progenitors were treated with AraC at various times (12, 24, 48 and 72 h and 6 days -NT2N cells-) where time points were chosen from previous studies . Equal amounts of total protein (12 μg) were loaded. The optical density (OD) is expressed as the percentage of immunoreactive signal found in NT2 progenitor cells (100%). Repeated measures one-way ANOVA followed by Tukey’s post hoc test. Significant differences between the different samples with respect to NT2 progenitors are shown (* p < 0.05; ** p < 0.01; *** p < 0.001). Data are mean ± SEM ( n = 4). C Immunoblots of <t>PLCβ1</t> on whole homogenates of NT2 progenitors, AraC-treated cells, and AraC/NT2N cells and NF200 and βIII-tubulin. Equal amounts of total protein (12 μg) were loaded.

Immunofluorescence images using anti-PLCβ1 (red), NF200 (green) and Hoechst’s chromatin staining (blue) of NT2 progenitors ( A ) and after treatment with RA ( A – F ) or AraC ( G – I ). Cells treated with RA were fixed and immunostained at 48 h ( B ), 7 days ( C ), 28 days ( D ), and after isolation of terminally differentiated NT2N neurons by mechanical dislodging ( E ). Non-neuronal cells (NT2A) that remained attached to the culture flask after the mechanical isolation of NT2N neurons were also doubly immunostained for PLCβ1 and NF200 ( F ). Cells treated with AraC were fixed at 48 h ( G ), 72 h ( H ) and 6 days, when cells were differentiated into NT2N neurons ( I ). Images are maximum intensity projections of four consecutive optical sections separated by 0.24 µm and obtained using a structured illumination module. Scale bar in F = 20 µm (applies to A – F ). Scale bar in I = 20 µm (applies to G – I ).
