caspase-1 Antibody (D-3) is a mouse monoclonal IgG1 kappa light chain antibody engineered to detect caspase-1, also known as IL-1 converting enzyme (ICE), across various applications including western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry, and enzyme-linked immunosorbent assay (ELISA). caspase-1 monoclonal antibody (D-3) targets a unique epitope spanning amino acids 367-391 near the C-terminus of human caspase-1, ensuring precise recognition of both the precursor and active forms of the protein in mouse, rat, and human samples. Caspase-1 is a pivotal protease involved in the inflammatory response and apoptosis, playing a crucial role in the maturation of pro-inflammatory cytokines interleukin-1β (IL-1β) and interleukin-18 (IL-18) through the proteolytic cleavage of their inactive precursors. Post-translational modifications of caspase-1, particularly autocatalytic cleavage into the p20 and p10 subunits, are essential for activation and subsequent enzymatic activity, which drives inflammatory signaling and programmed cell death. The structural integrity and regulation of caspase-1 through these modifications are vital for maintaining cellular homeostasis and responding to pathological stimuli. Dysregulation of caspase-1 activity has been implicated in various diseases, including chronic inflammation, septic shock, impaired wound healing, and certain leukemias, highlighting significance in both normal physiology and disease mechanisms. The human CASP1 gene, located on chromosome 2q14, encodes a cytoplasmic protein expressed in key tissues such as the liver, heart, skeletal muscle, kidney, and testis. By providing reliable detection of caspase-1 in various forms, caspase-1 (D-3) antibody is an indispensable tool for researchers investigating the intricate roles of this enzyme in immune responses and apoptotic pathways. Available in both non-conjugated and multiple conjugated forms, anti-caspase-1 antibody (D-3) facilitates versatile experimental approaches to elucidate the complex biology of caspase-1.

I am wondering if we can detect both pro and cleaved caspase 1 with this sc-392736 antibody as I always get two bands every time with 1: 750 dilution.

What is the difference between D-3 and D-4? Do these detect cleaved caspase 1 as well?

Asked by: cindyha_uot
Thank you for your question. These are both mouse monoclonal antibodies, but they are have different isotypes, and are raised against different antigens. The caspase-1 Antibody (D-3): sc-392736 is raised against an epitope mapping between amino acids 367-391 (human origin), and caspase-1 p20 Antibody (D-4): sc-398715 is raised against an epitope mapping between amino acids 259-294 (mouse origin). Both antibodies are expected to detect cleaved caspase, however (D-3) should recognize the p10 subunit, and (D-4) should recognize the p20 subunit. Please contact our Technical Service Department for help in choosing the best antibody for your research.

I used SC-1780 (caspase-1 Ab) to detect cleaved-caspase-1 (p20) polyclonal antibody. I would like to change the Ab to SC-392736 monoclonal Ab. But there is not any comment for detection of cleaved-caspase-1 (p20) protein. Can I detect using SC-392736?

Asked by: Jeong H
Thank you for your question. We would not recommend this mouse monoclonal, caspase-1 Antibody (D-3): sc-392736, for detection of the cleaved caspase-1 p20 subunit. This antibody is specific for an epitope mapping between amino acids 367-391 near the C-terminus of caspase-1 of human origin. And according to Uniprot, the p20 subunit corresponds to a different region between amino acids 120-297. http://www.uniprot.org/uniprot/P29466#ptm_processing
