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.

Chromatin IP Assays

This antibody has been validated for use in ChIP and/or ChIP-Seq, and can be used with Active Motif's ChIP-IT® High Sensitivity Kit or our magnetic bead-based ChIP-IT® Express Kits.

Some products may be shipped at room temperature. This will not affect their stability or performance. Upon receipt, unconjugated antibodies may be stored at -20°C for up to 2 years. Fluorophore- & enzyme-conjugated antibodies should be stored at 4°C. Fluorophore-conjugated antibodies should be protected from light. Keep reagents on ice when not in storage; to avoid repeated freeze/thaw cycles, we recommend aliquoting items that will be stored frozen into single-use fractions prior to freezing.


This product is guaranteed for 6 months from date of receipt.
