Immunofluorescence (IF)
(Fluorescent confocal image of HeLa cells stained with 037528. HeLa cells were fixed with 4% PFA (20 min), permeabilized with Triton X-100 (0.2%, 30 min), then incubated with 037528 (1:100, 2h at RT). For secondary antibody, Alexa Fluor 488 conjugated donkey anti-rabbit antibody (green) was used (1:1000, 1h). Cytoplasmic actin was counterstained with Alexa Fluor 555 (red) conjugated Phalloidin (5.25uM, 25 min). Note the highly specific localization of the phosphorylated KLF4 immunoreactivity to the nuclei but not the cytoplasm.)

Related Product Information for anti-KLF4 antibody
Kr¸ppel-like factor 4 (KLF4) is a transcription factor involved in both proliferation and differentiation in the colon. It is down-regulated in both mouse and human colonic adenomas and has been implicated as a tumor suppressor in the gut, whereas in breast cancer, KLF4 is an oncogene. KLF4 is also involved in reprogramming differentiated cells into pluripotent stem cells. KLF4 can act as a transcriptional activator or repressor, but the underlying mechanisms are poorly understood.

Product Notes
The KLF4 klf4 (Catalog #AAA6313975) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The KLF4 (S457) (KLF4, EZF, GKLF, Krueppel-like factor 4, Epithelial zinc finger protein EZF, Gut-enriched krueppel-like factor) (APC) reacts with Human and may cross-react with other species as described in the data sheet. AAA Biotech's KLF4 can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB), Immunofluorescence (IF), FLISA. Applications are based on unconjugated antibody. Researchers should empirically determine the suitability of the KLF4 klf4 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "KLF4, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
