Thymidylate synthase catalyzes the methylation of deoxyuridylate to deoxythymidylate using 5,10-methylenetetrahydrofolate (methylene-THF) as a cofactor. This function maintains the dTMP (thymidine-5-prime monophosphate) pool critical for DNA replication and repair. The enzyme has been of interest as a target for cancer chemotherapeutic agents. It is considered to be the primary site of action for 5-fluorouracil, 5-fluoro-2-prime-deoxyuridine, and some folate analogs. Expression of this gene and that of a naturally occuring antisense transcript rTSalpha (GeneID:55556) vary inversely when cell-growth progresses from late-log to plateau phase.
Applications:
Suitable for use in ELISA, Immunofluorescence, Immunohistochemistry, and Western Blot. Other applications not tested.
Recommended Dilution:
Immunohistochemistry (paraffin): 1.5ug/ml
ELISA: 1ug/ml-3ng/ml
Western Blot: 1:500-1:1000
Optimal dilutions to be determined by the researcher.
Hybridoma:
Sp2/0 myeloma cells with spleen cells from Balb/c mice.
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile 40-50% glycerol, aliquot and store at -20 degrees C. Aliquots are stable for at least 6 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
