Abstract: Methods comprising the use of photoactivated chemical bleaching for detecting multiple targets in a biological sample are provided. The methods include the steps of binding at least one probe to one or more target present in a biological sample including multiple targets, and detecting a signal from the probe. The method further includes the steps of contacting the sample comprising the bound probe with a photoinitiator and irradiating the sample, thereby initiating a photoactivated chemical bleaching process that substantially inactivates the probe. The method further includes the steps of binding at least one probe to one or more target present in the sample, and detecting a signal from the probe. The process of binding, detecting and bleaching may be iteratively repeated.

Abstract: The present invention relates to dimeric pentadentate chelators with exceptionally strong binding of metal ions, for detection, immobilization and purification of biomolecules. Dimeric chelators offer a cooperativity of binding of two adjacent immobilized metal ions simultaneously to a histidine-tagged biomolecule, which gives advantageous properties regarding strength of binding compared to a corresponding monomer chelator. In addition, a dimer increases the selectivity (ease of separation) against non-tagged biomolecules with low metal-ion affinity.

Abstract: A method of screening a plurality of fluid samples for the presence of species capable of specifically binding to a binding partner immobilized on a sensing surface of a sensor is disclosed. The method comprises contacting each sample with the sensing surface and a reference surface, and subjecting the sensing surface responses obtained for all samples to a computational process which comprises fitting al responses to a model equation for the relationship between a response at the sensing surface and the corresponding response at the reference surface. In an iterative process residuals above a pre-determined threshold value are removed, the model equation is adjusted, and all remaining samples are refitted to the adjusted model equation until the model equation at least substantially converges. Residuals above the predetermined threshold value are considered as species specifically binding to the binding partner.
