The CD103 antibody, clone Ber-ACT8, is derived using standard cell hybridization procedures using spleen cells from BALB/c mice immunized with the HTLV-1–positive T-cell line, MAPS16.

The CD103 antibody recognizes the αE subunit of integrin αEβ, an integrin also known as the human mucosal lymphocyte (HML) antigen 1, but not α, another member of the βintegrin subfamily. Integrin αEβis a trimeric protein complex of three components, 105 kilodaltons (kDa) (β), 150 kDa, and 25 kDa. The CD103 antibody recognizes an epitope localized on the 150-kDa chain.

R-Phycoerythrin (PE), is part of the BD family of Phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 496 nm and 566 nm and an emission maximum (Em Max) at 576 nm. PE is designed to be excited by the Blue (488 nm), Green (532 nm) and Yellow-Green (561 nm) lasers and detected using an optical filter centered near 575 nm (e.g., a 575/26-nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of Blue, Green, and Yellow-Green lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
