Scientific Data Images for Human FoxJ1 Antibody

Detection of Human FoxJ1 antibody by Western Blot.

Detection of Human FoxJ1 by Western Blot.

Western blot shows lysates of Capan-1 human pancreatic adenocarcinoma cell line and T47D human breast cancer cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human FoxJ1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3619) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for FoxJ1 at approximately 55 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
FoxJ1 antibody in HEK293 Human Cell Line by Immunocytochemistry (ICC).

FoxJ1 in HEK293 Human Cell Line.

FoxJ1 was detected in immersion fixed HEK293 human embryonic kidney cell line using Goat Anti-Human FoxJ1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3619) 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.
FoxJ1 antibody in Early Proximal Lung Progenitors by Immunocytochemistry (ICC).

FoxJ1 in Early Proximal Lung Progenitors.

FoxJ1 was detected in immersion fixed BGO1V human embryonic stem cells differentiated to early proximal lung progenitors using Goat Anti-Human FoxJ1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3619) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to nuclei.

Background: FoxJ1

FoxJ1 (Forkhead box protein J1; also HFH4) is a 55-65 kDa, class 1 member of the HNF-3/forkhead gene family of transcription factors. Its observed MW is higher than its predicted MW (45 kDa), suggesting anomalous migration on SDS-PAGE. FoxJ1 promotes the expression of cilia in respiratory, oviduct and choroid plexus epithelium, and maintains T cell tolerance to self-antigens. Human FoxJ1 is 421 amino acids (aa) in length, and contains one forkhead DNA binding domain (aa's 120‑210). The presence of basic residues in the forkhead domain makes FoxJ1 a class 1 Fox protein. There is potential splice variant that contains a 25 aa substation for aa 262-287. Over aa 306-421, human FoxJ1 shares 88% aa with mouse FoxJ1.
