Our Abpromise guarantee covers the use of ab25877 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
IHC-P Use a concentration of 2 µg/ml.
ICC/IF Use a concentration of 20 µg/ml.
WB Use a concentration of 1 - 2 µg/ml. Predicted molecular weight: 40 kDa.


  • FunctionReceptor for interleukin-33 (IL-33), its stimulation recruits MYD88, IRAK1, IRAK4, and TRAF6, followed by phosphorylation of MAPK3/ERK1 and/or MAPK1/ERK2, MAPK14, and MAPK8. Possibly involved in helper T-cell function.
  • Tissue specificityHighly expressed in kidney, lung, placenta, stomach, skeletal muscle, colon and small intestine. Isoform A is prevalently expressed in the lung, testis, placenta, stomach and colon. Isoform B is more abundant in the brain, kidney and the liver. Isoform C is not detected in brain, heart, liver, kidney and skeletal muscle.
  • Sequence similaritiesBelongs to the interleukin-1 receptor family.
    Contains 3 Ig-like C2-type (immunoglobulin-like) domains.
    Contains 1 TIR domain.
