CENP-B (Centromere protein B) is a protein associated with centromeric DNA and crucial to the formation of the special chromatin structure on the α-satellite DNA repeats of the human centromere. CENP-B specifically binds a 17 bp sequence which may function as a cis-element for centromere-specific nucleosome assembly. CENP-B plays a role in the organization of centromere satellite DNA into a higher order structure, directing centromere formation and kinetochore assembly in mammalian chromosomes.

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).

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.
