CST, 81327SF, Thymidylate Synthase (D5B3) Rabbit Monoclonal Antibody (BSA and Azide Free)

Monoclonal Antibody for studying Thymidylate Synthase. Validated for WB,IHC,IF,F. Highly specific and rigorously validated in-house, Thymidylate Synthase (D5B3) Rabbit Monoclonal Antibody (BSA and Azide Free) (CST #81327) is ready to ship. Product Usage Information This product is the carrier free version of product #9045. 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 # 9045 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 Thymidylate Synthase (D5B3) Rabbit Monoclonal Antibody (BSA and Azide Free) detects endogenous levels of total thymidylate synthase protein. Species Reactivity: Human, Mouse, Rat, Monkey Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human thymidylate synthase protein. Background The methylation of deoxyuridine monophosphate (dUMP) to deoxythymidine monophosphate (dTMP) is an essential step in the formation of thymine nucleotides (1,2, reviewed in 3). This process is catalyzed by thymidylate synthase (TS or TYMS), a homodimer composed of two 30 kDa subunits. TS is an intracellular enzyme that provides the sole source of thymidylate, making it a required enzyme in DNA biosynthesis with activity highest in proliferating cells (1). Being the exclusive source of dTMP, investigators have concluded that TS is also an important target for anticancer agents such as 5-fluorouracil (5-FU) (1-5). 5-FU acts as a TS inhibitor and is active against solid tumors such as colon, breast, head, and neck. Research studies have demonstrated that patients with metastases expressing lower levels of TS have a higher response rate to treatment with 5-FU than patients with tumors that have increased levels of TS (5). Researchers continue to investigate TS expression in different types of cancers (6-10). Levels of thymidylate synthase can be modultated by treatment with various drugs, such as 5-FU and lapatinib. 5-FU treatment induces the formation of two distinct bands, one at 35 kDa and another at 38 kDa, while lapatinib treatment results in a decrease in thymidylate synthase expression (11,12).
