  • Western blot analysis of extracts from Raji (lane2(20μg), MCF-7(lane3(20μg), SH-SY5Y(lane4(20μg) and Jurkat(lane5(20μg) using HP1 alpha Antibody (HY-P81280). Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST at 4°C overnight. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80993, 1/10,000) was used in 5% non-fat milk in TBST for 2 hour at room temperature. Goat Anti-Mouse IgG-HRP Secondary Antibody (HY-P8004, 1/10,000) was used for 1 hour at room temperature.

  • Immunohistochemical analysis of paraffin-embedded human breast cancer tissue using HP1 alpha Antibody (YA981). The section was pre-treated using heat mediated antigen retrieval with Tris/EDTA buffer (pH 9.0) for 20 minutes. The tissues were probed with the primary antibody (HY-P81280, 1/100) overnight at 4℃. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with neutral balsam.

  • Immunocytochemistry analysis of HeLa cells labeling HP1 alpha with HP1 alpha Antibody (HY-P81280) at 1/100 dilution . Cells were fixed in 4% paraformaldehyde for 15 minutes at room temperature, permeabilized with 0.1% Triton X-100 in PBS for 15 minutes at room temperature, then blocked with quick block buffer for 10 minutes at room temperature. Cells were then incubated with HP1 alpha Antibody (HY-P81280) at 1/100 dilution in quick block buffer overnight at 4 ℃.AF488-conjugated Goat Anti-Mouse IgG H&L(HY-P8005, Green) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. The Nuclear counterstain was DAPI (Blue).

Background
Function:Component of heterochromatin that recognizes and binds histone H3 tails methylated at 'Lys-9' (H3K9me), leading to epigenetic repression. In contrast, it is excluded from chromatin when 'Tyr-41' of histone H3 is phosphorylated (H3Y41ph) (PubMed:19783980). May contribute to the association of heterochromatin with the inner nuclear membrane by interactions with the lamin-B receptor (LBR) (PubMed:19783980). Involved in the formation of kinetochore through interaction with the MIS12 complex subunit NSL1 (PubMed:19783980, PubMed:20231385). Required for the formation of the inner centromere (PubMed:20231385)
Subcellular Localization:Nucleus; Chromosome; Chromosome, centromere
Subunit:Homodimer (PubMed:20819937). Interacts with histone H3 methylated at 'Lys-9' (PubMed:11242053, PubMed:21047797).

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
