Western Blotting (WB), Immunohistochemistry (Paraffin-embedded Sections) (IHC (p))
Specificity
This antibody recognises an epitope within the N-terminal region (NT) of Caspase-4, otherwise known as ICH-2. This antibody detects a band of approximately 34 kDa in Ramos cell lysates (predicted precursor MWT 31 kDa).

Caspase-4, a member of the Caspase-1 subfamily of cysteine proteases, exists as an inactive pro-enzyme which undergoes proteolytic cleavage of its p30 precursor form, into smaller p20 and p10 subunits. The cellular localisation of Caspase-4 on the Endoplasmic Reticulum (ER) membrane, has resulted in this protein becoming a focus of studies in which dysfunction or stress to the ER membrane is implicated, such as Alzheimers disease and Ischemia (1, 3) and confirms the involvement of Caspase-4 as an instigator of cellular apoptosis.Synonyms: CASP4, ICE(rel)-II, ICH2, Protease ICH-2, Protease TX
