Immunocytochemistry/ Immunofluorescence - Anti-p15 INK4b antibody [EPR29010-111] (AB323851)

Immunofluorescent analysis of 100% methanol-fixed, 0.1% TritonX-100 permeabilized MCF7 (human breast adenocarcinoma epithelial cell) cells labelling p15 INK4b with ab323851 at 1/100 (5.08 ug/ml) dilution, followed by ab150081 Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed antibody at 1/ab150081 1000 2ug/ml dilution (Green).

Confocal image showing increased cytoplasmic staining in MCF7 cells (shown in green) treated with TGFβ (10 ng/mL) for 18 hr. The counterstain was observed in magenta. Nuclear DNA was labelled with DAPI (shown in blue). Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

ab195889 Anti-alpha Tubulin mouse monoclonal antibody - Microtubule Marker (Alexa Fluor® 594) was used to counterstain tubulin at 1/ab195889 200 2.5ug/ml dilution (Magenta). The Nuclear counterstain was DAPI (Blue).

Secondary antibody only control : Secondary antibody is ab150081 Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed at 1/ab150081 1000 2ug/ml dilution.

Western blot - Anti-p15 INK4b antibody [EPR29010-111] (AB323851)

Blocking and diluting buffer and concentration : 5% NFDM/TBST.

The expression profile/ molecular weight observed is consistent with what has been described in the literature (PMID : 12202478).

The expression of p15 INK4b is upregulated in response to TGF beta treatment (PMID : 12202478).

The identity of the bands higher than 15 kDa are unknown.

To minimize protein degradation, cells were lysed immediately after harvest and then applied to a gel and transfer membrane for Western blotting as soon as possible.
