General description

All ChIPAb+ antibodies are individually validated for chromatin precipitation, every lot, every time. Each ChIPAb+ antibody set includes control primers (tested every lot by qPCR) to biologically validate your IP results in a locus-specific context. The qPCR protocol and primer sequences are provided, allowing researchers to validate ChIP protocols when using our antibody in their chromatin context. Each set also includes a negative control antibody to ensure specificity of the ChIP reaction.
The ChIPAb+ MED1 (CRSP1/TRAP220) set includes a MED1 antibody, a Normal Rabbit IgG, and positive control primers which amplify 85 bp of a human prostate-specific antigen (PSA) enhancer region. The MED1 antibody and negative control IgG are supplied in a scalable "per ChIP" reaction size and can be used to functionally validate the precipitation of MED1 associated chromatin.

Specificity

Wide species reactivity expected based upon conservation of immunogen sequence.

Immunogen

Epitope: Human MED1 (a.a. 1525-1581).
Recombinant protein corresponding to human MED1 (a.a. 1525-1581).

Application

Chromatin Immunoprecipitation:
Sonicated chromatin prepared from hormone starved (72H), then androgen agonist induced (1 µM CI-4AS-1 overnight) LNCaP cells (~1e6 cell equivalents per IP) were subjected to chromatin immunoprecipitation using 2 µg of either Normal Rabbit IgG (Part No. PP64B), or 2 µg Anti-MED1 (Part No.CS207349) and the Magna ChIP HiSens (Cat. # 17-10460). Successful immunoprecipitation of MED1 associated DNA fragments was verified by qPCR using ChIP Primers, PSA (Part No. CS207340) as a positive locus, and ChIP Primers, β-globin (Part No. CS200591) as a negative locus.
Please refer to the Magna ChIP HiSens (Cat. # 17-10460) or EZ-MagnaChIP HiSens(Cat. # 17-10461) protocol for experimental details.

Chromatin Immunoprecipitation:
Sonicated chromatin prepared from hormone starved (72H), then androgen agonist induced (1 µM CI-4AS-1 overnight) LNCaP cells (1e5 and 1e6 cell equivalents per IP) were subjected to chromatin immunoprecipitation using 2 µg of either Normal Rabbit IgG (Part No. PP64B), or 2 µg Anti-MED1 (Part No. CS207349) and the Magna ChIP HiSens Kit (Cat. # 17-10460). Successful immunoprecipitation of MED1 associated DNA fragments was verified by qPCR using ChIP Primers, PSA (Part No. CS207340).
Please refer to the MagnaChIP HiSens (Cat. # 17-10460) or EZ-MagnaChIP HiSens (Cat. # 17-10461) protocol for experimental details.

Western Blotting Analysis:
0.04 µg/mL of this antibody detected MED1 on 5, 15 and 50 µg of HeLa whole cell lysate.
