Anti-Indoleamine 2,3-dioxygenase Antibody, clone 10.1

42-45kDa

Indoleamine 2,3-dioxygenase (IDO) is an enzyme that is responsible for converting tryptophan to kynurenines. IDO is expressed by a wide variety of tissues and IDO can be upregulated by interferon gamma. IDO modulates levels of the amino acid tryptophan, which is vital for cell growth, but is also involved in the suppression of the immune response. IDO may be involved in the suppression of the immune response to tumours and blocking the IDO pathway may be a potential target for immunotherapy.

Amino acids 78-184 of human IDO fused to GST.

Anti-Indoleamine 2, 3-dioxygenase Antibody, clone 10.1 is an antibody against Indoleamine 2 for use in IH & WB.

Immunohistochemistry:
A previous lot of this antibody worked on lightly fixed tissues; Triton X-100 treatment only in the block, not with primary antibody. High temperature antigen retrieval is recommended.

Western blot:
Recognizes a 42-45kDa band in IFN-gamma treated human HeLa cell lines. Mouse IDO runs slightly smaller in blots than human IDO.

Optimal working dilutions must be determined by end user.
