Immunogen E. coli-derived recombinant human IL-2
Clone Polyclonal AB
Antibody Isotype IgG
Preparation This antibody was produced from a sheep immunized with purified human IL-2 protein.
Formulation and Storage The IgG fraction of immunized serum was purified by antigen affinity chromatography and lyophilized from a 0.2 um filtered solution in phosphate-buffered saline (PBS). Lyophilized samples are stable for 2 years from the date of receipt when stored at -70C
Specificity Detects human IL-2 in direct ELISAs and Western blots. In direct ELISAs, approximately 75% crossreactivity with recombinant rabbit IL-2 is observed, less than 50% cross-reactivity with recombinant canine IL-2, recombinant equine IL-2, recombinant porcine IL-2, recombinant feline IL-2, and recombinant cotton rat IL-2 is observed, and approximately 10% cross-reactivity with recombinant bovine IL-2, recombinant mouse IL-2 and recombinant rat IL-2 is observed.
Reconstitution Reconstitute the antibody with 100 ul sterile PBS and the final concentration is 500ug/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.
