This assay has high sensitivity and excellent specificity for detection of human IL-4. No significant cross-reactivity or interference between human IL-4 and analogues was observed. Note: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between human IL-4 and all the analogues, therefore, cross reaction may still exist.

Reagent Preparation
Biotin-antibody (1×) - Centrifuge the vial before opening. HRP-avidin (1×) - Centrifuge the vial before opening. Wash Buffer (1×) - If crystals have formed in the concentrate, warm up to room temperature and mix gently until the crystals have completely dissolved. Standard - Centrifuge the standard vial at 6000-10000rpm for 30s.
Assay Precision
Intra-assay Precision (Precision within an assay): CV%<8% Three samples of known concentration were tested twenty times on one plate to assess. Inter-assay Precision (Precision between assays): CV%<10% Three samples of known concentration were tested in twenty assays to assess.
Storage
