Human IFN-alpha2 bioluminescent ELISA kit 2.0
Rapid bioluminescent human IFN-α2 ELISA kit
LumiKine™ Xpress hIFN-α 2.0 is InvivoGen’s second-generation bioluminescent human interferon-alpha (hIFN-α) ELISA, using a Lucia luciferase-conjugated detection antibody. LumiKine™ Xpress hIFN-α 2.0 is an optimized ‘sandwich’ ELISA kit designed to rapidly and reliably measure the concentration of hIFN-α2 in various biological samples (cell culture supernatant, serum, and plasma).
After a single 2-hour incubation, the detection of hIFN-α2 is instantly determined using QUANTI-Luc™ 4 Reagent, a Lucia luciferase detection reagent. The bioluminescent signal is readily assessed by luminometry.
Features of LumiKine™ Xpress hIFN-α 2.0:
- Single incubation: 2 hours
- Limit of Detection: 5 pg/ml
- Specificity: hIFN-α2 (multiple subtypes can also be detected)
- Optimized antibody pairing: The capture and detection antibodies bind to different epitopes of the cytokine
- No cross-reactivity with hIFN-β, murine (m)IFN-α2 or mIFN-β
LumiKine™ Xpress hIFN-α 2.0 is provided with a standard recombinant hIFN-α2 produced in mammalian cells, to ensure the most accurate and sensitive calibration for the measurement of unknown levels of hIFN-α.
Figure 1: (A) A 7-point standard curve (beginning at 1000 pg/ml) was generated using a two-fold serial dilution of standard hIFN-α2. (B) Human peripheral blood mononuclear cells (PBMCs) were either stimulated with 2’3’ cGAMP, a STING agonist or left unstimulated. After 16 hours, the supernatant was isolated and the concentration of hIFN-α in both samples was quantified using LumiKine™ Xpress hIFN-α 2.0.
Incubation time: 2 hours (after plate preparation)
Limit of detection: 5 pg/ml
