Bioptix, Inc., formerly Venaxis, Inc., provides Enhanced Surface Plasmon Resonance (SPR) platform for the detection of molecular interactions. The Company's line of Enhanced SPR instruments are designed to increase the flexibility and reliability of SPR. Its SPR biosensors shed light on important binding parameters that are crucial for determining whether a biologic or small molecule drug will be efficacious in humans and at what dose a drug should be administered. Its technology is an ultra-sensitive detection platform. The design of its SPR spectrometers allows discrete areas within the sample cell to be interrogated simultaneously by use of photo-diode arrays aligned to the reflected beam from the sample cell. Its biosensors provide information on kinetic processes (association and dissociation), binding affinities, analyte concentrations and real-time molecule detection. The Company offers 404pi Enhanced SPR System, which enables real-time detection of biomolecular interactions.
