  • Description
    Sheep polyclonal to Thymidylate Synthase
  • Tested applicationsSuitable for: ELISA, IP, IHC-P, WBmore details
  • Species reactivity
    Reacts with: Mouse, Rat, Human, Escherichia coli , African green monkey
    Does not react with: Saccharomyces cerevisiae
  • Immunogen

    Recombinant human Thymidylate Synthase (36 kDa) produced in E.coli.

  • Positive control
    • HeLa cells treated with the TS inhibitor 5-FUdR
  • General notesThe antibody recognizes the expected additional band corresponding to the ternary complex of human TS-dFUMP-reduced folate in HeLa cells treated with the TS inhibitor 5-FUdR. This event occurs in most human breast, colorectal, gastric, head and neck carcinomas. The antibody recognizes 36 kDa human TS.



Our Abpromise guarantee covers the use of ab7398 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
ELISA Use at an assay dependent concentration.
IP Use at an assay dependent concentration.

Pre-clearing with a non-specific sheep IgG is helpful to reduce background.

IHC-P Use at an assay dependent concentration.
WB Use at an assay dependent concentration. Predicted molecular weight: 37 kDa.


Anti-Thymidylate Synthase antibody images

  • Predicted band size : 37 kDa
  • IHC image of Thymidylate Synthase staining in Human colon carcinoma formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol B. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab7398, 5µg/ml, for 15 mins at room temperature. A Rabbit anti-Sheep biotinylated secondary antibody was used to detect the primary, and visualized using an HRP conjugated ABC system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

This is a polyclonal antibody, and so we cannot refer to subclasses. The concentration is 10mg/ml and the sensitivity can be seen from the recommended concentrations for each application.

This antibody was raised against the full length recombinant protien. The epitopes recognised by this antibody have not been mapped.

This antibody was raised against a recombinant protein. A carrier protein was not used for immunisation.

The antibody is an IgG fraction. Unfortunatly we do not have an example to hand of the Western blot. However, the antibody works very well in Western blotting and we recommend this antibody for this application.

Yes, the anti-hTS does work on paraffin.
