General Notes
This product (Catalog No. DPABH-20147) is a rabbit-derived IgG polyclonal antibody raised against human INCENP, targeting the amino acid region 51–150 of the protein. This antibody exhibits cross-reactivity with INCENP from mouse, rat, and cow. It has been affinity purified by Protein A. In mammalian cells, 2 broad groups of centromere-interacting proteins have been described: constitutively binding centromere proteins and 'passenger,' or transiently interacting, proteins (reviewed by Choo, 1997). The constitutive proteins include CENPA (centromere protein A; MIM 117139), CENPB (MIM 117140), CENPC1 (MIM 117141), and CENPD (MIM 117142). The term 'passenger proteins' encompasses a broad collection of proteins that localize to the centromere during specific stages of the cell cycle (Earnshaw and Mackay, 1994 [PubMed 8088460]). These include CENPE (MIM 117143); MCAK (MIM 604538); KID (MIM 603213); cytoplasmic dynein (e.g., MIM 600112); CliPs (e.g., MIM 179838); and CENPF/mitosin (MIM 600236). The inner centromere proteins (INCENPs) (Earnshaw and Cooke, 1991 [PubMed 1860899]), the initial members of the passenger protein group, display a broad localization along chromosomes in the early stages of mitosis but gradually become concentrated at centromeres as the cell cycle progresses into mid-metaphase. During telophase, the proteins are located within the midbody in the intercellular bridge, where they are discarded after cytokinesis (Cutts et al., 1999 [PubMed 10369859]).
DPABH-20147 is suitable for use in IHC-P (1:100–1:500), IHC-F (1:100–1:500), IF (immunofluorescence) (1:100–1:500), ICC/IF (1:100–1:500), ELISA (1:5,000–1:10,000) applications.
DPABH-20147 is supplied as a liquid formulation in 0.01M TBS (pH7.4) with 1% BSA, 0.02% Proclin300 and 50% Glycerol. For long-term storage, keep at −20 °C. For short-term use, store at 2–8 °C. Avoid repeated freeze–thaw cycles to maintain antibody integrity and performance.
