IL-2 is a potent lymphoid cell growth factor which exerts its biological activity primarily on T cells, promoting proliferation and maturation. Additionally, IL-2 has been found to stimulate growth and differentiation of B cells, NK cells, LAK cells, monocytes, and oligodendrocytes.Product Details

- Cat, Chimpanzee, Baboon, Cynomolgus, Rhesus, Sooty Mangabey
- Antibody Type
- Host Species
- E. coli - expressed recombinant human IL-2
- Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide and BSA (origin USA)
- The antibody was purified by affinity chromatography and conjugated with APC/Fire™ 810 under optimal conditions.
- Lot-specific (to obtain lot-specific concentration and expiration, please enter the lot number in our Certificate of Analysis online tool.)
- Storage & Handling
- The antibody solution should be stored undiluted between 2°C and 8°C, and protected from prolonged exposure to light. Do not freeze.
ICFC - Quality tested
- Recommended Usage
Each lot of this antibody is quality control tested by intracellular immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is 5 µL per million cells in 100 µL staining volume or 5 µL per 100 µL of whole blood. It is recommended that the reagent be titrated for optimal performance for each application.
* APC/Fire™ 810 has a maximum excitation of 650 nm and a maximum emission of 810 nm.
Excessive exposure to light, and commonly used fixation, permeabilization buffers can affect APC/Fire™ 810 fluorescence signal intensity and spread. Please keep conjugates protected from light exposure. For more information and representative data, visit our Fire Dyes page.

- Application Notes
ELISA or ELISPOT Capture2,3: The purified MQ1-17H12 antibody is useful as the capture antibody in a sandwich ELISA or ELISPOT assay, when used in conjunction with the Biotin anti-human IL-2 antibody (Cat. No. 517605) as the detecting antibody. The Ultra-LEAF™ purified antibody is suggested for ELISPOT capture. For ELISPOT capture applications, a concentration range of 4.0 - 8.0 µg/mL is recommended.
Additional reported applications (for the relevant formats) include: immunoprecipitation2, immunohistochemical staining of paraformaldehyde-fixed, saponin-treated frozen tissue sections1,4-6,8, neutralization13, and immunocytochemistry.
Note: For testing human IL-2 in serum or plasma, BioLegend's LEGEND MAX™ Kit (Cat. No. 431807) is specially developed and recommended.
