This AID antbody was raised against a peptide corresponding to amino acids 178-198 of human AID.


Purified IgG in 50 mM Tris-HCl (pH 7.2), 30% glycerol, and 0.035% sodium azide. Sodium azide is highly toxic.


AID antibody (mAb) tested by Western blot.
Murine spleen cells were probed with AID antibody at a dilution of 3 µg/ml.

Lane 1: Unstimulated spleen cells from wild type mice.
Lane 2: Treated (LPS & IL4 for 96 hrs) spleen cells from wild type mice.
Lane 3: Unstimulated spleen cells from AID knock-out mice.
Lane 4: Treated (LPS & IL4 for 96 hrs) spleen cells from AID knock-out mice.


AID (Activation-induced cytidine deaminase, AICDA) is a member of the cytidine and deoxycytidylate deaminase family. It acts act as a single-strand DNA deaminase involved in somatic hypermutation, gene conversion and class-switch recombination in developing B-cells and is necessary for efficient antibody responses. It has also been implicated in active DNA demethylation, as deamination of methylcytosine yields thymine, which is read as a mismatch and is replaced by DNA damage repair enzymes.
