Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-KLF4 antibody [EPR20753-25] - BSA and Azide free (AB255335)
Immunohistochemical analysis of paraffin-embedded Rat colon tissue labeling KLF4 with ab214666 at 1/1000 dilution, followed by a ready to use Goat Anti-Rabbit IgG H&L (HRP) secondary antibody. Nuclear staining on epithelial cells of rat colon (PMID : 21070761, PMID : 19109406) is observed. Counterstained with Hematoxylin.
Secondary antibody only control : Used PBS instead of primary antibody, secondary antibody is a ready to use Goat Anti-Rabbit IgG H&L (HRP).
This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab214666).
Perform heat mediated antigen retrieval with EDTA buffer pH 9 before commencing with IHC staining protocol.

Immunocytochemistry/ Immunofluorescence - Anti-KLF4 antibody [EPR20753-25] - BSA and Azide free (AB255335)
Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized F9 (mouse embryonal carcinoma epithelial cell) cells labeling KLF4 with ab214666 at 1/100 dilution, followed by a AlexaFluor®488 Goat anti-Rabbit secondary (ab150077) at 1/1000 dilution (Green). Confocal image showing nuclear staining in F9 cell line is observed. The nuclear counterstain was DAPI (Blue). Tubulin was counterstained using an Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594, ab195889, Red).
Secondary antibody only control : Used PBS instead of primary antibody, secondary antibody is a AlexaFluor®488 Goat anti-Rabbit secondary (ab150077) at 1/1000.
This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab214666).

Immunoprecipitation - Anti-KLF4 antibody [EPR20753-25] - BSA and Azide free (AB255335)
KLF4 was immunoprecipitated from 0.35 mg F9 (Mouse embryonal carcinoma epithelial cell) whole cell lysate using ab214666 at 1/30 dilution. Western blot was performed on the immunoprecipitate using ab214666 at 1/1000 dilution. VeriBlot for IP secondary antibody (HRP) (ab131366) was used as the secondary at 1/5000 dilution.
Lane 1 : F9 whole cell lysate 10 µg (input).
Lane 2 : ab214666 IP in F9 whole cell lysate.
Lane 3 : Rabbit monoclonal IgG (ab172730) instead of ab214666 in F9 whole cell lysate.
Blocking and dilution buffer and concentration : 5% NFDM/TBST.
Exposure time : 3 minutes.
Fresh lysate was required and IP test was conducted immediately. Incubation time was shortened from overnight to 2h.
This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab214666).

This data was developed using ab214666, the same antibody clone in a different buffer formulation.
Several embryos at the mid-blastocyst stage (~E3.75) were tested. The embryos were fixed for 10 mins at room temperature in 4% PFA. Fixed embryos were washed for 5 mins in PBS + 0.1% Triton X-100 (PBX) at room temperature. The embryos were then permeabilized in PBS + 0.5% Triton X-100 + 100mM Glycine for 5 mins at room temperature and washed again in PBX for 5 mins at room temperature. Blocking was carried out for 1 hour at room temperature in PBS + 2% horse serum and then the embryos were incubated overnight in ab214666 (1/1000) diluted in blocking solution. The next day embryos were washed three times for 5 mins each in PBX, before blocking again for 1 hour at room temperature. Then incubated in Donkey anti rabbit Alexa Fluor® 488 secondary antibodies (1/500) diluted in blocking solution for 1 hour at 4°C. This was followed by 2 washes of 5 mins each in PBX. The embryos were then incubated in PBS + 5μg/ml DAPI for 10 min, or until mounting for imaging. Images were acquired on a laser-scanning confocal microscope system. Displayed image shows maximum intensity projection of 5 optical sections acquired at 1μm increments. Scale bar : 20 μm

Biological function summary
KLF4 impacts cell differentiation and proliferation through its role as a transcription factor. It functions within several cellular complexes and interacts with other transcription factors to modulate gene expression. KLF4 regulates stem cell maintenance by influencing gene networks involved in self-renewal and differentiation contributing particularly to pluripotency in embryonic stem cells.
Pathways
The transcriptional activity of KLF4 integrates into key signaling pathways like the Wnt/β-catenin and Notch pathways. Within the Wnt/β-catenin pathway KLF4 may cooperate with β-catenin and TCF/LEF transcription factors to modulate gene targets. Similarly in the Notch signaling pathway KLF4 interacts with pathway components to influence cell fate decisions. These interactions highlight KLF4's central role in orchestrating complex signaling networks.
