|IHC-P||1/50. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.|
ab172730 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.
FunctionStimulates transcription. Binds to purine-rich DNA sequences. Can form a ternary complex with the serum response factor and the ETS and SRF motifs of the fos serum response element.
Tissue specificityLung and testis.
Sequence similaritiesBelongs to the ETS family.
Contains 1 ETS DNA-binding domain.
modificationsSumoylation represses transcriptional activator activity as it results in recruitment of HDAC2 to target gene promoters which leads to decreased histone acetylation and reduced transactivator activity. It also regulates nuclear retention.
On mitogenic stimulation, phosphorylated on C-terminal serine and threonine residues by MAPK1. Ser-383 and Ser-389 are the preferred sites for MAPK1. In vitro, phosphorylation by MAPK1 potentiates ternary complex formation with the serum responses factors, SRE and SRF. Phosphorylation leads to loss of sumoylation and restores transcriptional activator activity.

Lane 1: Wild-type HAP1 whole cell lysate (20 µg)
Lane 2: ELK1 knockout HAP1 whole cell lysate (20 µg)
Lane 3: HeLa positive whole cell lysate (21 µg)
Lane 4: MCF7 negative whole cell lysate (20 µg)
Lanes 1 - 4: Merged signal (red and green). Green - ab32106 observed at 55 kDa. Red - loading control, ab18058, observed at 130 kDa.
ab32106 was shown to specifically react with ELK1 in wild-type HAP1 cells as signal was lost in ELK1 knockout cells. Wild-type and ELK1 knockout samples were subjected to SDS-PAGE. Ab32106 and ab18058 (Mouse anti-Vinculin loading control) were incubated overnight at 4°C at 1/500 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
Immunocytochemistry/ Immunofluorescence analysis of A549 (human lung carcinoma epithelial cell) cells labeling ELK1 with purified ab32106 at 1/500 dilution (3.8 µg/mL). Cells were fixed in 4% Paraformaldehyde and permeabilized with 0.1% tritonX-100. Goat anti rabbit IgG (Alexa Fluor® 488, ab150077) was used as the secondary antibody at 1/1000 (2 µg/mL) dilution. DAPI (blue) was used as nuclear counterstain.

Flow Cytometry analysis of HeLa (human cervix adenocarcinoma) cells labeling ELK1 with unpurified ab32106 at 1/20 dilution (10ug/mL) (red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. A Goat anti rabbit IgG (Alexa Fluor® 488) at 1/2000 dilution was used as the secondary antibody. Rabbit monoclonal IgG (Black) was used as the isotype control, cells without incubation with primary antibody and secondary antibody (Blue) were used as the unlabeled control.
