Application Dilution Species-Reactivity Sensitivity MW (kDa) Isotype
W Human Endogenous 40 Rabbit IgG

Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting, IP=Immunoprecipitation


Species predicted to react based on 100% sequence homology: Monkey.

Specificity / Sensitivity

AIM2 (D5X7K) Rabbit mAb recognizes endogenous levels of total AIM2 protein. An unknown band is detected at 22 kDa in some cell lines.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Lys93 of human AIM2 protein.

Western Blotting

Western Blotting

Western blot analysis of extracts from Daudi, KARPAS-299, and L-540 cell lines using AIM2 (D5X7K) Rabbit mAb.

Western Blotting

Western Blotting

Western blot analysis of extracts from HL-60 cells, serum-starved and either untreated (-) or treated overnight with Human Interferon-γ (hIFN-γ) #8901 (100 ng/ml; +), using AIM2 (D5X7K) Rabbit mAb (upper) or β-Actin (D6A8) Rabbit mAb #8457 (lower).

Western Blotting

Western Blotting

Western blot analysis of extracts from 293T cells, mock transfected (-) or transfected with a construct expressing Myc-DDK tagged human AIM2 (hAIM2-Myc/DDK; +), using AIM2 (D5X7K) Rabbit mAb (upper) and Myc-Tag (71D10) Rabbit mAb #2278 (lower).



Immunoprecipitation of AIM2 from HL-60 cell extracts treated with Human Interferon-γ (hIFN-γ) #8901 (100 ng/ml, overnight) using Rabbit (DA1E) mAb IgG XP® Isotype Control #3900 (lane 2) or AIM2 (D5X7K) Rabbit mAb (lane 3). Lane 1 is 10% input. Western blot was performed using AIM2 (D5X7K) Rabbit mAb.


Absent in melanoma 2 (AIM2) is an interferon-inducible protein containing an amino-terminal pyrin domain and carboxy-terminal HIN-200 domain that functions in innate immunity and tumor progression (1). Expression of AIM2 can inhibit cell growth and tumor formation (2,3). Furthermore, the AIM2 gene has a high frequency of mutations associated with microsatellite-unstable colorectal cancers (4). AIM2 has a critical role in the activation of caspase-1, the protease responsible for the processing of pro-inflammatory cytokines IL-1β and IL-18. Caspase-1 activation is regulated by multi-protein complexes referred to as “inflammasomes” (5,6). Distinct inflammasome complexes have been described containing NLRP1/NALP1, NLRP3/NALP3, IPAF, and AIM2. The HIN-200 domain of AIM2 is responsible for binding to cytoplasmic double stranded DNA, resulting in caspase-1 activation. (7-9). This inflammasome complex also involves binding of the pyrin domain of AIM2 to the CARD-domain protein ASC/TMS1, which then interacts directly with caspase-1. As a result, AIM2 has been demonstrated to be an important sensor for a number of different pathogens (10-12).
