Immunogen S. frugiperda insect ovarian cell line Sf 21-derived recombinant human IL-2 R alpha
Clone Polyclonal AB
Antibody Isotype IgG
Preparation This antibody was produced from a sheep immunized with purified human IL-2 R alpha protein.
Formulation and Storage The IgG fraction of immunized serum was purified by antigen affinity chromatography and lyophilized from a 0.2 µm filtered solution in phosphate-buffered saline (PBS). Lyophilized samples are stable for 2 years from date of receipt when stored at -70°C.
Specificity Detects human IL-2 R alpha in direct ELISAs and Western blots. In direct ELISAs and Western blots, less than 15% cross-reactivity with recombinant human (rh) IL-2 sR gamma is observed, less than 5% cross-reactivity with rhIL-6 sR is observed, and less than 1% cross-reactivity with rhIL-1 sRII and rhIL- 2 sR beta is observed. In direct ELISAs, less than 5% cross-reactivity with recombinant mouse IL-2 R alpha is observed.
Reconstitution Reconstitute the antibody with 100 µl sterile PBS and the final concentration is 500µg/ml. Reconstituted antibody can also be aliquoted and stored frozen at < -20 °C for at least for six months without detectable loss of activity. Avoid repeated freeze-thaw cycles.
