General description

105 kDa and 95 kDa
Every lot of the ChIPAb+ line of antibodies is individually validated for chromatin precipitation, in order to guarantee successful ChIP assays every time. Each antibody includes a control primer set for performance confirmation. Sp1 antibody and the negative control antibody (rabbit normal IgG) can be used to demonstrate that the Sp1 antibody is functionally validated in the precipitation of Sp1 associated chromatin.
The qPCR primers included flank the Sp1 binding site in human DHFR promoter.
Transcription factor SP1 can activate or repress transcription in response to physiological and pathological stimuli. Binds with high affinity to GC-rich motifs and regulates the expression of a large number of genes involved in a variety of processes such as cell growth, apoptosis, differentiation and immune responses. Highly regulated by post-translational modifications (phosphorylations, sumoylation, proteolytic cleavage, glycosylation and acetylation). Binds also the PDGFR-alpha G-box promoter. May have a role in modulating the cellular response to DNA damage. Implicated in chromatin remodeling. Plays a role in the recruitment of SMARCA4/BRG1 on the c-FOS promoter. Plays an essential role in the regulation of FE65 gene expression. In complex with ATF7IP, maintains telomerase activity in cancer cells by inducing TERT and TERC gene expression. Isoform 3 is a stronger activator of transcription than isoform 1. Positively regulates the transcription of the core clock component ARNTL/BMAL1.

Analysis Note

Chromatin immunoprecipitation:
Sonicated chromatin prepared from 1 x 106 HeLa cells was subjected to chromatin immunoprecipitation using 4 μg of either the negative control antibody, Rabbit Normal IgG or Rabbit Anti-Sp1 and the Magna ChIPTM A kit (Cat.# 17-610) Rapid Protocol (2 hour IP). Successful enrichment of Sp1 associated DNA fragments was verified by qPCR using ChIP Primers DHFR flanking the human DHFR promoter that contains a Sp1 binding site (Please see figures).
Please refer to the EZ-Magna ChIP A (Cat.# 17-408)
or EZ-ChIP (Cat.# 17-371) kit protocols for
experimental details.
Control
Includes negative control rabbit IgG and control primers specific for human dihydrofolate reductase (DHFR) promoter.

Advance your Epigenetics Research

Epigenetics describes heritable changes in gene expression caused by non-genetic mechanisms. Epigenetic regulation allows a cell to vary its response based on its biological and environmental contexts. Epigenetic changes can effect transcriptional and post-transcriptional regulation via mechanisms such as histone modification, chromatin and nucleosome remodeling, DNA methylation, and small and non-coding RNA-mediated regulation. These mechanisms, in cooperation with transcription factors and other nucleic acid-binding proteins, regulate gene expression. Epigenetic mechanisms of gene regulation impacts diverse areas of research—from agriculture to human health. Common epigenetic assays such as chromatin immunoprecipitation (ChIP) and RNA immunoprecipitation (RIP) rely on high quality antibodies that recognize specific epigenetic modifications for accurate results. EMD Millipore offers over 100 ChIPAb+™ and RIPAb+™ validated antibody kits that are quality tested on ChIP/RIP assays and are conveniently provided with control qPCR primers and negative control antibodies to ensure first time ChIP/RIP success.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
