Application Notes

This product has been discontinued

Applications Validated by Active Motif:
ChIP: 5 - 10 µl per ChIP
WB: 1:500 - 1:1,000 dilution

For optimal results in Western blotting, primary antibody incubations should be performed at 37°C. Individual optimization may be required.

Published Applications

The following applications have been published using this antibody. Unless noted above, Active Motif may not have validated the antibody for use in these applications:

ChIP, ChIP-Seq
IF/ICC
WB

Immunogen

This Sp1 antibody was raised against a synthetic peptide corresponding to amino acid residues 520-534 of human Sp1.

Buffer

PBS containing 0.2% gelatin, 0.01% thimersol and 0.1% sodium azide. Thimersol and sodium azide are highly toxic.

 

Sp1 antibody tested by ChIP.
Chromatin immunoprecipitation (ChIP) was performed using the ChIP-IT® High Sensitivity Kit (Cat. No. 53040) with 20 µg of chromatin from B cell lymphoma Namalwa cells and 6 µl of Sp1 antibody. ChIP DNA was used in qPCR with the control primer pairs or gene-specific primer pairs as indicated. Data are presented as Binding Events Detected per 1000 Cells using Active Motif's Epigenetic Services normalization scheme which accounts for primer efficiency and the amount of chromatin used in the ChIP reaction.

Sp1 antibody tested by Western blot.
Detection of Sp1 by Western blot analysis. Sp1 was detected in nuclear extracts derived from K-562 cells using Sp1 rabbit polyclonal antibody at a 1:1,000 dilution.

Background

Sp1 (specificity protein 1) is a human transcription factor involved in gene expression in the early development of an organism. The protein is 785 amino acids long, with a molecular weight of 81 kDa. The SP1 transcription factor contains a zinc finger protein motif, by which it binds directly to DNA and enhances gene transcription. Its zinc fingers are of the Cys2/His2 type and bind the consensus sequence 5′-(G/T)GGGCGG(G/A)(G/A)(C/T)-3′ (GC box element). It was discovered in 1983 and has since been modified to form Sp1C, which has a zinc finger protein DNA binding domain.

Positive Control

Active Motif's K-562 nuclear extract (Catalog No. 36015) can be used as a positive control for Sp1 antibody.

qPCR Primers

Active Motif's Human Negative Control Primer Set 1 (Cat. No. 71001) has been validated for performing qPCR and endpoint PCR when this antibody has been used for ChIP on human samples. For ChIP experiments with this antibody on mouse samples, the Mouse Negative Control Primer Set 1 (Cat. No. 71011) has been validated for both qPCR and endpoint PCR.

Chromatin IP Assays

This antibody has been validated for use in ChIP and/or ChIP-Seq, and can be used with Active Motif's ChIP-IT® High Sensitivity Kit or our magnetic bead-based ChIP-IT® Express Kits.
