Konfigurierbare Panels & Premixed-Kits
Unser breites Angebot enthält Multiplex-Panels, für die Sie die Analyten auswählen können, die am besten für Ihre Anwendung geeignet sind. Unter einem separaten Register können Sie das Premixed-Cytokin-Format oder ein Singleplex-Kit wählen.
Kits für die zelluläre Signaltransduktion & MAPmates™
Wählen Sie gebrauchsfertige Kits zur Erforschung gesamter Signalwege oder Prozesse. Oder konfigurieren Sie Ihre eigenen Kits mit Singleplex MAPmates™.
Die folgenden MAPmates™ sollten nicht zusammen analysiert werden: -MAPmates™, die einen unterschiedlichen Assaypuffer erfordern. -Phosphospezifische und MAPmate™ Gesamtkombinationen wie Gesamt-GSK3β und Gesamt-GSK3β (Ser 9). -PanTyr und locusspezifische MAPmates™, z.B. Phospho-EGF-Rezeptor und Phospho-STAT1 (Tyr701). -Mehr als 1 Phospho-MAPmate™ für ein einziges Target (Akt, STAT3). -GAPDH und β-Tubulin können nicht mit Kits oder MAPmates™, die panTyr enthalten, analysiert werden.

ChIPAb+ REST - ChIP Validated Antibody and Primer Set
Overview
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+™ REST set includes the REST antibody, a Normal Rabbit IgG, and control primers which amplify a 89 bp region of the human Snap25 promoter. The REST and negative controls are supplied in a scalable "per ChIP" reaction size and can be used to functionally validate the precipitation of REST associated chromatin.

Key Applications
Western Blotting
Chromatin Immunoprecipitation (ChIP)
Application Notes
Chromatin Immunoprecipitation: Sonicated chromatin prepared from HeLa cells (4e6 cell equivalents per IP) were subjected to chromatin immunoprecipitation using 4 µg of either Normal Rabbit IgG (Part No. PP64B), or 4 µg Anti-REST (Part No.CS207378) and the Magna ChIP™ HiSens (Cat. # 17-10460). Successful immunoprecipitation of REST associated DNA fragments was verified by qPCR using ChIP Primers, human Snap25 (Part No. CS207379) as a positive locus, and CDC25 as a negative locus. (Figure 2). Data is presented as percent input of each IP sample relative to input chromatin for each amplicon and ChIP sample as indicated.
Western Blotting Analysis: Human HEK293 cell lysate (30 ug) was resolved by electrophoresis, transferred to PVDF membrane and probed with the anti-REST (1:1000 dilution). Proteins were visualized using a secondary antibody conjugated to HRP and a chemiluminescence detection system. Data courtesy of Glen Corson laboratory of Gail Mandel, Oregon Health and Sciences University, Portland, OR. REST has a predicted molecular weight of 125 kDa. Observed size was ~200 kDa.
Biological Information
Immunogen
The REST purified antibody is made against a GST fusion protein corresponding to amino acids 801-1097 of human REST.
This gene encodes a transcriptional repressor which represses neuronal genes in non-neuronal tissues. It is a member of the Kruppel-type zinc finger transcription factor family. It represses transcription by binding a DNA sequence element called the neuron-restrictive silencer element. The protein is also found in undifferentiated neuronal progenitor cells, and it is thought that this repressor may act as a master negative regular of neurogenesis. Alternatively spliced transcript variants have been described; however, their full length nature has not been determined. [provided by RefSeq].
FUNCTION:Transcriptional repressor which binds neuron-restrictive silencer element (NRSE) and represses neuronal gene transcription in non-neuronal cells. Restricts the expression of neuronal genes by associating with two distinct corepressors, mSin3 and CoREST, which in turn recruit histone deacetylase to the promoters of REST-regulated genes. Mediates repression by recruiting the BHC complex at RE1/NRSE sites which acts by deacetylating and demethylating specific sites on histones, thereby acting as a chromatin modifier.
SUBUNIT STRUCTURE: Interacts with SIN3A, SIN3B and RCOR1.
SUBCELLULAR LOCATION: NucleusProbable.
TISSUE SPECIFICITY: Ubiquitous. Expressed at higher levels in the tissues of the lymphocytic compartment, including spleen, thymus, peripheral blood lymphocytes and ovary.
SEQUENCE CAUTION: The sequence AAA98503.1 differs from that shown. Reason: Frameshift at positions 189, 212 and 1087.
The sequence AAH38985.1 differs from that shown. Reason: Miscellaneous discrepancy. Contaminating sequence. Potential poly-A sequence.
