Rat IL-9 PharmaGenie ELISA Kit (SBRS1667)

The Rat IL-9 ELISA Kit from Assay Genie quantitatively measures Interleukin-9, a pleiotropic Th9/mast cell-derived cytokine implicated in allergic airway inflammation, parasitic helminth immunity, and tumor microenvironments. The assay delivers a detection range of 15.6 to 1000 pg/mL with a sensitivity below 5 pg/mL, requiring 100 µL of standard or sample per well. Researchers investigating Th2/Th9 polarization, asthma models, mast cell activation, or autoimmune dysregulation in rat systems can apply this reagent to serum, plasma, and cell culture supernatant samples using the biotin-conjugated detection antibody and streptavidin-HRP reporter chemistry. The recombinant rat IL-9 standard included with the kit supports a seven-point standard curve, and absorbance readings are taken after stop solution addition. Store kit components refrigerated at 4 °C for short-term use, and aliquot the standard if freezing at -20 °C for longer stability to minimize repeated freeze-thaw cycles.
