for HP1a antibody (pAb)Background

HP1 (Heterochromatin protein 1) is a chromosomal protein that participates in both chromatin packaging and gene silencing. Three HP1 isoforms (α, β and γ) occur in mammals. The chromodomain (Chromatin Organization Modifier) of HP1α is responsible for binding to Histone H3 methyl Lys9, although additional factors are required to specify the HP1 targeting. The chromoshadow domain mediates interactions with a number of nuclear proteins, including SuvH39 (a Histone H3 Lysine methyltransferase), the DNA methyltransferases DNMT1 and DNMT3A or the large subunit of the chromatin assembly factor-1 (CAF-1). Dysfunction of HP1α plays a critical role in tumorigenesis, and is implicated in the invasive/metastatic phenotype of breast cancer.

for HP1a antibody (pAb)Positive Control

Active Motif's HeLa nuclear extract (Catalog No. 36010) can be used as a positive control for HP1 alpha antibody.

for HP1a antibody (pAb)Storage

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.

for HP1a antibody (pAb)Guarantee

This product is guaranteed for 6 months from date of receipt.

This product is for research use only and is not for use in diagnostic procedures.
