LumiKine™ Xpress mIFN-β 2.0

Rapid bioluminescent murine IFN-β ELISA kit

LumiKine™ Xpress mIFN-β 2.0 is InvivoGen’s second-generation bioluminescent murine interferon-beta (mIFN-β) ELISA, using a Lucia luciferase-conjugated detection antibody. LumiKine™ Xpress mIFN-β 2.0 is an optimized ‘sandwich’ ELISA kit designed to rapidly and reliably measure the concentration of mIFN-β in various biological samples (cell culture supernatant, serum, and plasma).

After a single 2-hour incubation, the detection of mIFN-β is instantaneously determined using QUANTI-Luc™ 4 Reagent, a Lucia luciferase detection reagent. The bioluminescent signal is readily assessed by luminometry.

Features of LumiKine™ Xpress mIFN-β 2.0:

  • Single incubation: 2 hours
  • Limit of Detection: 5 pg/ml
  • Specificity: Murine IFN-β
  • Optimized antibody pairing: The capture and detection antibodies bind to different epitopes of the cytokine
  • No cross-reactivity with human (h)IFN-α2, hIFN-β or mIFN-α2

LumiKine™ Xpress mIFN-β 2.0 is provided with a standard recombinant mIFN-β produced in mammalian cells, to ensure the most accurate and sensitive calibration for the measurement of unknown levels of mIFN-β.


Figure 1: (A) A 7-point standard curve (beginning at 1000 pg/ml) was generated using a two-fold serial dilution of standard mIFN-β. (B) Wild type (WT) and STING knock out (KO-STING) mice were injected intraperitoneally with CL592 (2 x 100 mg/kg), a STING agonist. After 4 hours, serum was isolated and diluted 1/200 using DMEM and 10% heat-inactivated (HI)-FBS. The concentration of mIFN-β in both samples was quantified using LumiKine™ Xpress mIFN-β 2.0.
