| Gene Summary | The protein encoded by this gene is a zinc finger transcription factor that binds to GC-rich motifs of many promoters. The encoded protein is involved in many cellular processes, including cell differentiation, cell growth, apoptosis, immune responses, response to DNA damage, and chromatin remodeling. Post-translational modifications such as phosphorylation, acetylation, glycosylation, and proteolytic processing significantly affect the activity of this protein, which can be an activator or a repressor. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2014] |

WB
Western blot analysis of SP1 on different lysates with Rabbit anti-SP1 antibody at 1/1,000 dilution. Lane 1: HeLa cell lysate, Lane 2: 293T cell lysate, Lane 3: Jurkat cell lysate, Lane 4: U-2 OS cell lysate, Lane 5: COS-1 cell lysate, Lysates/proteins at 20 µg/Lane. Exposure time: 4 seconds; 4-20% SDS-PAGE gel. Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody at 1/1,000 dilution was used in 5% NFDM/TBST at 4℃ overnight. Goat Anti-Rabbit IgG - HRP Secondary Antibody at 1/50,000 dilution was used for 1 hour at room temperature.
IHC
Immunohistochemical analysis of paraffin-embedded human breast cancer tissue with Rabbit anti-SP1 antibody at 1/1,000 dilution. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) for 2 minutes. The tissues were blocked in 1% BSA for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody at 1/1,000 dilution for 1 hour at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.
ICC/IF
Immunocytochemistry analysis of HeLa cells labeling SP1 with Rabbit anti-SP1 antibody at 1/200 dilution. Cells were fixed in 4% paraformaldehyde for 10 minutes at 37 ℃, permeabilized with 0.05% Triton X-100 in PBS for 20 minutes, and then blocked with 2% negative goat serum for 30 minutes at room temperature. Cells were then incubated with Rabbit anti-SP1 antibody at 1/200 dilution in 2% negative goat serum overnight at 4 ℃. Goat Anti-Rabbit IgG H&L (iFluor™ 488) was used as the secondary antibody at 1/1,000 dilution. Nuclear DNA was labelled in blue with DAPI. Beta tubulin (red) was stained at 1/200 dilution overnight at +4℃. Goat Anti-Mouse IgG H&L (iFluor™ 594) was used as the secondary antibody at 1/1,000 dilution.
FC
Flow cytometric analysis of MCF-7 cells labeling SP1. Cells were fixed and permeabilized. Then stained with the primary antibody (1ug/ml) (red) compared with Rabbit IgG Isotype Control (green). After incubation of the primary antibody at +4℃ for an hour, the cells were stained with a iFluor™ 488 conjugate-Goat anti-Rabbit IgG Secondary antibody at 1/1,000 dilution for 30 minutes at +4℃. Unlabelled sample was used as a control (cells without incubation with primary antibody; black).
ChIP
Chromatin immunoprecipitations were performed with cross-linked chromatin from HeLa cells and either SP1 or Normal Rabbit IgG according to the ChIP protocol. The enriched DNA was quantified by real-time PCR using indicated primers. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.
IHC
Immunohistochemical analysis of paraffin-embedded mouse lung tissue with Rabbit anti-SP1 antibody at 1/200 dilution. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) (high pressure) for 2 minutes. The tissues were blocked in 1% BSA for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody at 1/200 dilution for 1 hour at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

IP
SP1 was immunoprecipitated from 0.2 mg HeLa cell lysate with Rabbit anti-SP1 antibody at 2 µg/10 µl beads. Western blot was performed from the immunoprecipitate using Rabbit anti-SP1 antibody at 1/1,000 dilution. HRP Conjugated Anti-Rabbit IgG for IP Nano-secondary antibody at 1/5,000 dilution was used for 1 hour at room temperature. Lane 1: HeLa cell lysate (input), Lane 2: Rabbit anti-SP1 antibody IP in HeLa cell lysate, Lane 3: Rabbit IgG instead of Rabbit anti-SP1 antibody in HeLa cell lysate, Blocking/Dilution buffer: primary antibody dilution, Exposure time: 6 seconds.| Application Notes | WB:1:1000-1:2000 IHC:1:200-1:1000 ICC:1:100-1:500 FC:1:500-1:1000 ChIP:Use 0.5~2ug for 25ug of chromatin.
