Application Abreviews Notes
WB 1/1000.
ChIP Use at an assay dependent concentration.
IP Use at an assay dependent concentration. PubMed: 20053746

  • FunctionTranscriptional regulator that binds to the upstream enhancer region (CCAC box) of myoglobin gene. Has a role in myogenic differentiation and in remodeling processes of adult muscles that occur in response to physiological stimuli.
  • Tissue specificityExpressed both developing and adult tissues. In adults, significant expression is seen in tumors of the brain, colon and lymph node.
  • Sequence similaritiesContains 1 FHA domain.
    Contains 1 fork-head DNA-binding domain.

    ab18196 staining in human rectum with colo-rectal cancer, showing staining of the tumour cells (in brown). Paraffin embedded rectal tissue was incubated with ab18196 (1:1000 dilution) for 30 mins at room temperature. Antigen retrieval was performed by heat induction in citrate buffer pH 6. ab18196 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.

  • ICC/IF image of ab18196 stained Hek293 cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab18196, 1µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899 Dylight 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

  • FOXK1 - ChIP Grade was immunoprecipitated using 0.5mg Hela whole cell extract, 5µg of Rabbit polyclonal to FOXK1 and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).
    The antibody was incubated under agitation with Protein G beads for 10min, Hela whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.
    Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70oC; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab18196.
    Secondary: Mouse monoclonal [SB62a] Secondary Antibody to Rabbit IgG light chain (HRP) (ab99697).
    Band: 96kDa:FOXK1.
