Background
Identification of human receptor for Interleukin-2 (IL-2R) expressing the 55,000 M.W. surface antigen.

Synonyms: CD25*APC

Source

Immunogen: CD25=Derived from the hybridization of mouse NS-1 myeloma cells with spleen cells of BALB/c mice immunized with PHA-activated human T-lymphocytes.

Product

Product Form: APC

Formulation: Provided as solution in phosphate buffered saline with 0.08% sodium azide and 0.2% carrier protein

Purification Method: Protein A/G Chromatography

Concentration: Titered for flow cytometry

Applications
PBMC: Add10 µl of MAB/10^6 PBMC in 100 µl PBS. Mix gently and incubate for 15 minutes at 2° to 8°C. Wash twice with PBS and analyze or fix with 0.5% v/v of paraformaldehyde in PBS and analyze. WHOLE BLOOD: Add10 µl of MAB/100 µl of whole blood. Mix gently and incubate for 15 minutes at room temperature 20°C. Lyse the whole blood. Wash once with PBS and analyze or fix with 0.5% v/v of paraformaldehyde in PBS and analyze. See instrument manufacturer’s instructions for Lysed Whole Blood and Immunofluorescence analysis with a flow cytometer or microscope.
