1/50. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
Staining of formalin-fixed tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0 for 10 min followed by cooling at RT for 20 min.
FunctionThiol protease that cleaves IL-1 beta between an Asp and an Ala, releasing the mature cytokine which is involved in a variety of inflammatory processes. Important for defense against pathogens. Cleaves and activates sterol regulatory element binding proteins (SREBPs). Can also promote apoptosis.
Tissue specificityExpressed in larger amounts in spleen and lung. Detected in liver, heart, small intestine, colon, thymus, prostate, skeletal muscle, peripheral blood leukocytes, kidney and testis. No expression in the brain.
Sequence similaritiesBelongs to the peptidase C14A family. Contains 1 CARD domain.
Post-translational modificationsThe two subunits are derived from the precursor sequence by an autocatalytic mechanism.
