Applications

Our Abpromise guarantee covers the use of ab16645 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IHC-FoFr 1/200 - 1/500. PubMed: 20364144
IP Use at an assay dependent concentration.
WB 1/5000. Detects a band of approximately 75 kDa (predicted molecular weight: 75 kDa).

ab16645 recognises the different isoforms of FOXP1 in Jurkat cell lysate (see review for further details).

IHC-P 1/200. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
ICC/IF 1/500.

Target

  • FunctionTranscriptional repressor. It plays an important role in the specification and differentiation of lung epithelium. Can act with CTBP1 to synergistically repress transcription but CTPBP1 is not essential. Essential transcriptional regulator of B cell development.
  • Involvement in diseaseNote=A chromosomal aberration involving FOXP1 is found in acute lymphoblastic leukemia. Translocation t(9;3)(p13;p14.1) with PAX5.
    Defects in FOXP1 are the cause of mental retardation with language impairment and autistic features (MRLIAF) [MIM:613670]. It is a developmental disorder characterized by mild to moderate mental retardation, language impairment, and autistic features. Patients show global delay, delayed walking, severely delayed speech development, and behavioral abnormalities, including irritability, hyperactivity, aggression, and stereotypical rigid behaviors.
  • Sequence similaritiesContains 1 C2H2-type zinc finger.
    Contains 1 fork-head DNA-binding domain.
  • DomainThe leucine-zipper is required for dimerization and transcriptional repression.
  • Cellular localizationNucleus.

    ab16645 staining FOXP1 in human small intestine. Paraffin embedded human small intestine tissue was incubated with ab16645 (1/200 dilution) for 30 mins at room temperature. Antigen retrieval was performed by heat induction in citrate buffer pH 6.

    ab16645 was tested in a tissue microarray (TMA) containing a wide range of normal and cancer tissues as well as a cell microarray consisting of a range of commonly used, well characterised human cell lines.

  • ab14404 staining FOXP1 in mouse pancreatic cancer primary cells by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with methanol/acetone (1:1), permeabilized with Triton 0.025% in PBS and blocked with 10% serum for 1 hour at room temperature. Samples were incubated with primary antibody (1/200 in PBS) for 4 hours. An Alexa Fluor®488-conjugated Donkey anti-rabbit polyclonal (1/1000) was used as the secondary antibody.

    Predicted band size : 75 kDa
    Observed band size : 65,82 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 45 kDa (possible cross reactivity),50 kDa (possible cross reactivity),85 kDa (possible cross reactivity).
  • ab16645 was tested in IHC of formalin fixed sections from mouse (over two weeks of age) brain. Antigen retrieval was in citrate buffer and blocking was in 1% BSA. The primary antibody was incubated at a dilution of 1/200 overnight at 4 degrees celsius. The secondary antibody was a biotin conjugated anti-rabbit IgG.
