  Flow Cytometry - Alexa Fluor® 647 Anti-Progesterone Receptor antibody [SP2] (ab267524)

  Overlay histogram showing T47D cells stained with ab267524 (red line). The cells were fixed with 4 % formaldehyde (10 min) and then permeabilized with 0.1 % PBS-Triton X-100 for 15 min. The cells were incubated in 1x PBS containing 10 % normal goat serum to block non-specific protein-protein interaction followed by the antibody (ab267524) (1x 10⁶ in 100μl at 0.2 μg/ml (1/2500)) for 30 min at 22°C.
  

  Isotype control antibody (black line) was Rabbit IgG (monoclonal) Alexa Fluor^® 647 (Alexa Fluor® 647 Rabbit IgG, monoclonal [EPR25A] - Isotype Control ab199093) used at the same concentration and conditions as the primary antibody. Unlabelled sample (blue line) was also used as a control.

  Acquisition of >5,000 events were collected using a 40 mW Red laser (640nm) and 670/14 bandpass filter.

  Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Alexa Fluor® 647 Anti-Progesterone Receptor antibody [SP2] (ab267524)

  IHC image of Progesterone Receptor staining in a section of formalin-fixed paraffin-embedded normal human breast*.

  The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6) in a Biocare Medical NxGen pressure cooker using retrieval settings of 110°C for 20 minutes. Non-specific protein-protein interactions were then blocked in TBS containing 0.025% (v/v) Triton X-100, 0.3M (w/v) glycine and 1% (w/v) BSA for 1h at room temperature. The section was then incubated overnight at +4°C in TBS containing 0.025% (v/v) Triton X-100 and 1% (w/v) BSA with ab267524 at 1/100 dilution (shown in red) and counterstained using Alexa Fluor® 488 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker ab195887, Mouse monoclonal to alpha Tubulin (Alexa Fluor^® 488), at 1/250 dilution (shown in green). Nuclear DNA was labelled with DAPI (shown in blue). The section was then mounted using Fluoromount^®.

  Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

  For other IHC staining systems (automated and non-automated), customers should optimize variable parameters such as antigen retrieval conditions, antibody concentrations and incubation times.

  Immunocytochemistry/ Immunofluorescence - Alexa Fluor® 647 Anti-Progesterone Receptor antibody [SP2] (ab267524)

  ab267524 staining Progesterone Receptor in T47D cells. The cells were fixed with 4% formaldehyde (10 min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated overnight at +4°C with ab267524 at 1/100 dilution (shown in red) and Alexa Fluor® 488 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker ab195887, Mouse monoclonal to alpha Tubulin (Alexa Fluor^® 488), at 1/250 dilution (shown in green). Nuclear DNA was labelled with DAPI (shown in blue).
