(tested or 100% immunogen sequence identity)
IL5 antibody was raised against cOS-expressed recombinant human IL-5.
Recognizes human Interleukin-5 (IL-5).
ELISA: Monoclonal antibody is useful as a capture or detection antibody in a sandwich ELISA for quantifying human IL-5 protein levels.1-3,5 Purified antibody may be paired with biotinylated antibody as the detection antibody, with purified recombinant human IL-5 as the standard. Or, conversely, biotinylated may be paired with purified antibody as the capture antibody. Immunofluorescence/Flow Cytometry: This antibody is useful for intracytoplasmic staining and flow cytometric analysis to identify and enumerate IL-5-positive cells within mixed cell populations.5,6 Recombinant human IL-5, unlabeled antibody, or Rat IgG1 should be used as a specificity control. Western Blot: The purified antibody is also useful for Western blotting applications. A concentration of 1-5 ug/ml (in conjunction with AP-labeled Goat Anti-Rat-Ig) has been found to enable detection of 100 ng/lane of recombinant human IL-5 under reducing conditions. The applications listed have been tested for the unconjugated form of this product. Other forms have not been tested.
Short term: 4°C; Long term: Add glycerol (40-50%) -20°C.
