ATF4 (Phospho-Ser245) Polyclonal Antibody
Catalog No.: 43053
Format: 100ul at 1.0mg/ml in PBS (without Mg2+ and Ca2+), pH 7.4, 150mM NaCl, 0.02% sodium azide and 50% glycerol. Affinity-purified on phosphopeptide; non-phosphopeptide- reactive antibodies were removed by chromatography on non-phosphorylated peptide.
ATF4 encodes a transcription factor that was originally identified as a widely expressed mammalian DNA-binding protein that could bind a tax-responsive enhancer element in the LTR of HTLV-1. ATF4 belongs to a family of DNA-binding proteins that includes the AP-1 family of transcription factors, cAMP-response element binding proteins (CREBs) and CREB-like proteins. These transcription factors share a leucine zipper region that is involved in protein-protein interactions located C-terminal to a stretch of basic amino acids that functions as a DNA binding domain. Diseases associated with ATF4 include leukoencephalopathy with vanishing white matter and T-cell leukemia.
Antigen: Peptide sequence that includes phosphorylation sites of serine 245 (N-R-S(p)-L-P) derived from human ATF4 and conjugated to KLH.
Accession no.: P18848, NP_001666.2
Host Species: Rabbit
This antibody detects endogenous human ATF4 only when phosphorylated at serine 245.
Immunoblotting: use at dilution of 1:500-1:1,000. A band of ~45kDa is detected.
Immunohistochemistry: use at dilution of 1:50- 1:100.
These are recommended working dilutions. Enduser should determine optimal dilutions for their applications.
Dilute in PBS or medium that is identical to that used in the assay system.
STORAGE AND STABILITY
This antibody is stable for at least one (1) year at -20°C. Can be stored at 4°C for short-term use.
For in vitro investigational use only. Not intended for therapeutic or diagnostic applications.
