CST, 76191SF, C/EBP beta (E2K1U) Rabbit Monoclonal Antibody (BSA and Azide Free)

Monoclonal Antibody for studying C/EBP-beta. Validated for WB,IHC,IF,F. Highly specific and rigorously validated in-house, C/EBP beta (E2K1U) Rabbit Monoclonal Antibody (BSA and Azide Free) (CST #76191) is ready to ship. Product Usage Information This product is the carrier free version of product #43095. All data were generated using the same antibody clone in the standard formulation which contains BSA and glycerol. This formulation is ideal for use with technologies requiring specialized or custom antibody labeling, including fluorophores, metals, lanthanides, and oligonucleotides. It is not recommended for ChIP, ChIP-seq, CUT&RUN or CUT&Tag assays. If you require a carrier free formulation for chromatin profiling, please contact us . Optimal dilutions/concentrations should be determined by the end user. BSA and Azide Free antibodies are quality control tested by size exclusion chromatography (SEC) to determine antibody integrity. Formulation Supplied in 1X PBS (10 mM Na 2 HPO 4 , 3 mM KCl, 2 mM KH 2 PO 4 , and 140 mM NaCl (pH 7.8)). BSA and Azide Free. For standard formulation of this product see product # 43095 Storage Store at -20°C. This product will freeze at -20°C so it is recommended to aliquot into single-use vials to avoid multiple freeze/thaw cycles. A slight precipitate may be present and can be dissolved by gently vortexing. This will not interfere with antibody performance. Specificity / Sensitivity C/EBP beta (E2K1U) Rabbit Monoclonal Antibody (BSA and Azide Free) recognizes endogenous levels of total C/EBPβ protein. This antibody does not cross-react with C/EBPα protein. Species Reactivity: Human, Monkey Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly67 of human C/EBPβ protein. Background C/EBPβ is a member of the transcription factor family of CCAAT/enhancer-binding proteins (C/EBPs) that are critical for cellular differentiation and function (1). There are various N-terminally truncated C/EBPβ isoforms: full-length C/EBPβ, C/EBPβ-LAP (liver-enriched activator protein), and C/EBPβ-LIP (liver-enriched inhibitory protein). In triple-negative breast cancer cells, aerobic glycolysis was shown to control the expression of C/EBPβ-LAP, which in turn stimulates the expression of granulocyte colony-stimulating factor (G-CSF) and granulocyte macrophage colony-stimulating factor (GM-CSF). These factors are secreted from the cancer cells to promote myeloid-derived suppressor cell (MDSC) development in the tumor microenvironment, thereby suppressing anti-tumor immunity (2). In addition, research studies showed that decreased C/EBPβ-LIP expression delays age-related phenotypes in mice, suggesting a potential role for C/EBPβ-LIP in aging (3).
