ControlPositive Control: 5-FU-resistant colon carcinoma cell lines (NCI H630R10, NCI630R1), 5-FU-resistant breast cancer cell lines, MCF-Ad5 and MCF-Ad10

Application

Use Anti-Thymidylate Synthase Antibody, clone TS106 (Mouse Monoclonal Antibody) validated in ELISA, FC, IF, IHC, IHC(P), IP, WB to detect Thymidylate Synthase also known as Thymidylate synthase.

ELISA:
A previous lot of this antibody was used in ELISA.

Flow Cytometry:
A previous lot of this antibody was used in FC.

Immunofluorescence:
A previous lot of this antibody was used in IF.

Immunoprecipitation:
A 10 µL/mg concentration of a previous lot was used on protein lysate.

Immunohistochemistry (Frozen and Paraffin sections):
1:50 - 1:100 (with incubation for 30-60 minutes at room temperature). TS106 can benefit from antigen retrieval with either EDTA pH 8.0 or 10mM citrate buffer pH 6.0 .

Western Blotting:
1:200 - 1:400. Recognizes a 36KDa band.

General description

TS (EC:2.1.1.45), a cytosolic enzyme, is a dimmer of two identical monomers of about 36kDa. The enzyme provides the sole intracellular de novo source of thymidylate and plays a crucial role in DNA replication and repair. TS catalyzes the methylation of deoxyuridine monophosphate (dump) and its conversion to deoxythymidine monophosphate (dTMP). Therefore, TS is primarily active in proliferating and metabolic active cells. TS is a central target of the widely used antineoplastic agent 5-Fluorouracil (5-FU) and thus also of the Xeloda, which is enzymatically activated to 5-FU. TS is inactivated by a covalent complex formation with 5-FdUMP and methylenetetrahydrofolate. Literature indicates that expression of TS is associated with response to 5-fluorouracil (5-FU) in human breast, colorectal, gastric, head, and neck carcinomas with low TS expression predicting better response to 5-FU and survival.
