2A3

The CD25 antibody, clone 2A3. is derived from the hybridization of NS-1 mouse myeloma cells with spleen cells isolated from BALB/c mice immunized with PHA-activated human T lymphocytes.

The CD25 antibody recognizes a 55-kilodalton (kDa) type I integral membrane glycoprotein. The CD25 antigen is also known as the human low-affinity interleukin-2 receptor α chain (IL-2Rα) and the Tac antigen.

FITC
Fluorescein (FITC) is part of the BD blue family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 494-nm and an emission maximum (Em Max) at 518-nm. FITC is designed to be excited by the Blue laser (488-nm) and detected using an optical filter centered near 520 nm (e.g., a 530/30-nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
