Background Information

The 2-prime,5-prime oligoadenylate synthetases (OASs), such as OAS1, are interferon-induced proteins characterized by their capacity to catalyze the synthesis of 2-prime,5-prime oligomers of adenosine (2-5As). OAS1 (type I enzymes) have molecular weights of 42, 44, 46, and 48 kDa, form tetramers, and contain a single consensus sequence(PMID:12590567). OAS1 is a strong candidate for determining susceptibility or resistance to viral infections(PMID:15732009). This antibody may have weak cross-reaction with OAS3 protein due to the highly homology.

Seong (Verified Customer) (11-27-2018)

OAS1 polyclonal antibody (14955-1-AP) did work by Western Blot (1:1,500) of ARPE-19 cells induced with interferon gamma but the band was very weak in uninduced cells.

  • Applications: Western Blot,
  • Primary Antibody Dilution: 1:1,500
  • Cell Tissue Type: human ARPE-19 cells
