OAS2 in U266 Human Cell Line. OAS2 was detected in immersion fixed U266 human myeloma cell line using Mouse Anti-Human OAS2 Monoclonal Antibody (Catalog # MAB1925) at 3 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm. Staining was performed using our protocol for Fluorescent ICC Staining of Non-adherent Cells.

Background: OAS2

OAS2, also known as OAS (69 kDa), is one of three related proteins (along with OAS1 and OAS3) that catalyze the conversion of ATP into 2’,5’-linked adenosine oligomers with the general formula pppA(2’,5’A)_n where n > 1 (2, 3) These proteins are induced by interferons, activated by double-stranded RNA, and are implicated in anti-viral immunity (1, 4, 5).
