Description

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+ LSD1 (KDM1A) set includes a LSD1 antibody, a Normal rabbit IgG and positive control primers which amplify a 85bp human prostate-specific antigen enhancer region. The LSD1 antibody and negative control IgG are supplied in a scalable "per ChIP" reaction size and can be used to functionally validate the precipitation of LSD1 associated chromatin.

LSD1 (lysine specific demethylase 1), also known as BHC110, is a histone demethylase that specifically demethylates Lys4 of histone H3, a specific tag for epigenetic transcriptional activation, thereby acting as a corepressor. LSD1 acts by oxidizing the substrate by FAD to generate the corresponding imine that is subsequently hydrolyzed. LSD1 demethylates both mono- and tri-methylted Lys4 of histone H3, and may play a role in the repression of neuronal genes. Alone, it is unable to demethylate H3 Lys4 on nucleosomes and requires the presence of RCOR1/CoREST to achieve such activity. LSD1 may also demethylate Lys9 of histone H3, a specific tag for epigenetic transcriptional repression, thereby leading to derepression of androgen receptor target genes.

Immunogen

Histidine-tagged recombinant protein corresponding to full length LSD1.

Application

Chromatin Immunoprecipitation:
Sonicated chromatin prepared from hormone starved (72 hrs), then androgen agonist induced (1 µM CI-4AS-1 overnight) LNCaP cells (~1e5 cell equivalents per IP) were subjected to chromatin immunoprecipitation using 2 µg of either Normal Rabbit IgG (Part No. PP64B), or 2 µg Anti-LSD1 (Part No.CS207350) and the Magna ChIP HiSens (Cat. # 17-10460). Successful immunoprecipitation of LSD1 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-Magna ChIP HiSens(Cat. # 17-10461) protocol for experimental details.

Chromatin Immunoprecipitation:
Sonicated chromatin prepared from hormone starved (72 hrs), 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-LSD1 (Part No. CS207350) and the Magna ChIP HiSens Kit (Cat. # 17-10460). Successful immunoprecipitation of LSD1 associated DNA fragments was verified by qPCR using ChIP Primers, PSA (Part No. CS207340).

Western Blotting Analysis:
HeLa nuclear extract was probed with Anti-LSD1 (0.05 μg/mL).
Proteins were visualized using a Donkey Anti-Rabbit IgG secondary antibody conjugated to HRP and a chemiluminescence detection system.
