KLF5 Antibody [Unconjugated]

Western blot shows lysates of BG01V human embryonic stem cells, D3 mouse embryonic stem cell line, and P19 mouse embryonal carcinoma cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human KLF5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3758) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for KLF5 at approximately 50-55 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

KLF5 was detected in immersion fixed D3 mouse embryonic stem cell line using Goat Anti-Human KLF5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3758) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red, upper panel; Catalog # NL001) and counterstained with DAPI (blue, lower panel). Specific staining was localized to nuclei and cytoplasm. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Simple Western lane view shows lysates of D3 mouse embryonic stem cell line, loaded at 0.2 mg/mL. A specific band was detected for KLF5 at approximately 64 kDa (as indicated) using 10 µg/mL of Goat Anti-Human/Mouse KLF5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3758) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the12-230 kDa separation system.

Western blot shows lysates of HeLa human cervical epithelial carcinoma parental cell line and KLF5 knockout HeLa cell line (KO). PVDF membrane was probed with 1 µg/mL of Goat Anti-Human/Mouse KLF5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3758) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for KLF5 at approximately 53 kDa (as indicated) in the parental HeLa cell line, but is not detectable in knockoutHeLa cell line. GAPDH (Catalog # AF5718) is shown as a loading control. This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background

Human KLF5, also known as basic transcription element binding protein 2 (BTEB2), is a widely expressed 51 kDa (457 aa) member of the kruppel C2H2-type zinc finger protein family. KLF5 contains three C2H2-type zinc fingers at the carboxyl-terminus that preferentially bind to cis-DNA elements that are GC rich. It is a transcription activator that promotes cell proliferation and oncogenesis. Over the region used as immunogen, human, mouse and canine KLF5 share 95% aa sequence identity.

Limitations

This product is for research use only and is not approved for use in humans or in clinical diagnosis. Primary Antibodies are guaranteed for 1 year from date of receipt.
