Novus Biologicals rabbit anti ki67 ab
Characterisation of H9C2 proliferating clones whose genome was modified within the Tmpo gene sequence by CRISPR-Cas9 to reduce or extinguish LAP2a protein expression. ( A ) Schema of the Tmpo gene and LAP2a protein domains. The following are indicated: the number of base pairs targeted by one of the SgRNAs within the Tmpo gene and the amino acid position; the mutations induced by our SgRNA (at protein level) for the four H9C2 clones selected as effectively edited to trigger a premature stop codon; the names of the WT +/+ (unedited CRISPR clones) and of the LAP2a +/- and LAP2a -/- clones considered throughout this study. ( B ) Western blots are shown for whole protein extracts of naive H9C2 and CRISPR clones (WT (21E10, 21B1, 22A11); LAP2a +/- (21H4, 22G2, 22G3) and LAP2a -/- (22B3)), as indicated. Proteins of interest were detected using anti LAP2a Ab (middle panel) and anti TMPO Ab (lower panel). Red Ponceau staining (upper panel) was used to normalize ECL signals. ( C ) The graphs show the ECL signal quantification of western blots (arbitrary units; a.u) after revelation with anti TMPO Ab as shown in 1B. The graphs present the individual values and means ± s.e.m. (N= 2 to 5 independent samples per clone). * p<0.05, ** p<0.01, **** p<0.0001 (Mann Whitney test). ( D ) Immunofluorescence of CRISPR clones (WT (22A11, 21B1), LAP2a -/- (22B3) and LAP2a +/- (21H4)), using a rabbit Ab to detect LAP2a (red), phalloidin to label cytoplasmic actin (green) and DAPI to label nuclear DNA (blue). Scale bar = 50 um. ( E ) The graphs represent the % of cells with either a negative (-) or relatively higher or lower (+, ++, +++) mean signal (a.u) as detected by immunofluorescence when using a rabbit anti LAP2a Ab, as shown in 1D. For the analysed experiment (N = 1), the total n (numbers of cell nuclei) were 184, 321, 174 and 216 for the clones 22B3, 22A11, 21H4 and 21B1, respectively. ( F ) The graph represents the cell doubling time (mean value ± s.e.m.) calculated for naive H9C2 cells, WT CRISPR clones, LAP2a +/- and LAP2a -/- CRISPR edited clones, as indicated. The individual values and means ± s.e.m are given. (N = 4 to 8 independent experiments per clone). * p<0.05; **** p<0.0001. (Mann Whitney test) ( G ) The graph represents the amount of cells that were either positively (green) or negatively (black) stained in situ by immunofluorescence for the proliferation marker <t>Ki67.</t> For the analysed experiment (N = 1), the total n (numbers of cells) were 499, 562 and 647 for the WT, LAP2a +/- and LAP2a -/- clones, respectively. * p<0.05. *** p<0.001 (Chi square test for a contingency table).
