HICE1 PS70 (Internal Region) antibody

Catalog No. ABIN1043901

Product Details

Target: HICE1 PS70

Binding Specificity: Internal Region

Reactivity: Human

Host: Rabbit

Clonality: Polyclonal

Conjugate: Un-conjugated

Application: ELISA, Western Blotting (WB)

Specificity: Hice1 pS70 affinity purified antibody is directed against the phosphorylated form of human Hice1 protein at the pS70 residue. The product was affinity purified from monospecific antiserum by immunoaffinity purification.  Antiserum was first purified against the phosphorylated form of the immunizing peptide.  The resultant affinity purified antibody was then cross adsorbed against the non-phosphorylated form of the immunizing peptide.  The antibody is specific for the phosphorylated form of Hice1.   Reactivity with non-phosphorylated human Hice1 is minimal by ELISA and western blot.  A BLAST analysis was used to suggest cross reactivity with Hice1 from human based on 100% sequence homology with the immunogen.  Reactivity against homologues from other sources is not known.

Characteristics: Hice1 pS70 is designed, produced, and validated as part of a collaboration with the National Cancer Institute (NCI) and is suitable for Cancer, Immunology and Nuclear Signaling research. Hice1 contributes to the mitotic spindle assembly, maintenance of centrosome integrity and completion of cytokinesis as part of the HAUS augmin-like complex. Normal bipolar spindle formation is critical for accurate chromosome segregation and proper mitotic progression. Failure in this event leads to spindle checkpoint activation and chromosome missegregation that ultimately leads to aneuploidy. Hice1 binds to microtubules directly, and promotes spindle integrity and chromosome stability. Hice1 has also shown to play an important role in targeting the gammaTuRC complex to the mitotic spindle, a step that appears to be required for spindle-mediated microtubule generation and normal chromosome segregation. The HAUS augmin-like complex's interaction with microtubules is strong during mitosis, while it is weak or absent during interphase. During interphase, it is primarily cytoplasmic, associating with centrosomes and with the mitotic spindles, preferentially at the spindle pole vicinity. During anaphase and telophase, it additionally associates with the spindle midzone and midbody, respectively. Further characterization of the function of Hice1 will likely be important for better understanding the mechanism of normal mitotic progression and high fidelity chromosome segregation.

Sterility: Sterile filtered

Immunogen: Anti-Hice1 pS70 Antibody was prepared by repeated immunizations with a phosphorylated synthetic peptide corresponding to the region of amino acids containing serine 70 of Hice1.
Immunogen Type: Peptide

Isotype: IgG

Application Details

Application Notes: Hice1 pS70 antibody has been tested for use in ELISA and by western blot.  Specific conditions for reactivity should be optimized by the end user. Expect a band approximately 44.9 kDa in size corresponding to human phosphorylated Hice1 protein by western blotting in the appropriate stimulated tissue or cell lysate or extract.
