This antibody was raised against a recombinant protein corresponding to the N-terminus of drosophila CID.


Purified IgG in PBS with 30% glycerol and 0.035% sodium azide. Sodium azide is highly toxic.



CID (Centromer Identifier) is the Drosophila histone H3 variant which replaces canonical H3 in centromeric chromatin at the inner plate of the kinetochore (similar to mammalian CENP-A). CID is required for recruitment and assembly of kinetochore proteins, mitotic progression and chromosome segregation. It may serve as an epigenetic mark that propagates centromere identity through DNA replication and cell division.

Compatible Secondary Antibodies

Active Motif has developed a variety of high-quality secondary antibodies for most applications, with anti-rabbit and anti-mouse conjugates to a broad line of high-quality fluorescent molecules, as well as horse radish peroxidase (HRP). Visit our Secondary Antibody Conjugates page to find the perfect secondaries for immunofluorescence experiments with CID antibody (mAb).


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.
