Reproducibility is key to advancing scientific discovery and accelerating scientists’ next breakthrough.
Abcam is leading the way with our range of recombinant antibodies, knockout-validated antibodies and knockout cell lines, all of which support improved reproducibility.
We are also planning to innovate the way in which we present recommended applications and species on our product datasheets, so that only applications & species that have been tested in our own labs, our suppliers or by selected trusted collaborators are covered by our Abpromise™ guarantee.
In preparation for this, we have started to update the applications & species that this product is Abpromise guaranteed for.
We are also updating the applications & species that this product has been “predicted to work with,” however this information is not covered by our Abpromise guarantee.
Applications & species from publications and Abreviews that have not been tested in our own labs or in those of our suppliers are not covered by the Abpromise guarantee.
Please check that this product meets your needs before purchasing. If you have any questions, special requirements or concerns, please send us an inquiry and/or contact our Support team ahead of purchase.

PurityImmunogen affinity purified
Purification notesab113358 was purified from goat serum by ammonium sulphate precipitation followed by antigen affinity chromatography using the immunizing peptide.
Our Abpromise guarantee covers the use of ab113358 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||Use a concentration of 0.3 - 1 µg/ml. Detects a band of approximately 48 kDa (predicted molecular weight: 25 kDa).
1 hour primary incubation is recommended for this product.
|IHC-P||Use at an assay dependent concentration.|
FunctionInvolved in T-cell activation, the induction of cell proliferation and cytokine production and promotion of T-cell survival.
Tissue specificityExpressed in T-cells and plasma cells, but not in less mature B-cells.
Sequence similaritiesContains 1 Ig-like V-type (immunoglobulin-like) domain.
