Abstract: The present invention relates to an immunoglobulin-binding protein, wherein at least one asparagine residue has been mutated to an amino acid other than glutamine or aspartic acid, which mutation confers an increased chemical stability at pH-values of up to about 13-14 compared to the parental molecule. The protein can for example be derived from a protein capable of binding to other regions of the immunoglobulin molecule than the complementarity determining regions (CDR), such as protein A, and preferably the B-domain of Staphylococcal protein A. The invention also relates to a matrix for affinity separation, which comprises an immunoglobulin-binding protein as ligand coupled to a solid support, in which protein ligand at least one asparagine residue has been mutated to an amino acid other than glutamine.

Abstract: Fluorescence microscopy systems with polychroic mirror changers are described. In one aspect, a polychroic mirror changer includes a polychroic-mirror array. The array includes a plate with a planar surface and a number of holes formed in the plate. The array also includes polychroic mirrors attached to the planar surface of the plate such that each polychroic mirror covers one of the holes and the reflective surface of each polychroic mirror is adjacent to and aligned with the planar surface of the plate. Each polychroic mirror is partially exposed through a corresponding hole to reflect a different subset of excitation channels of a beam of excitation light input to the changer. The polychroic-mirror array can be mounted in the changer so that when a different subset of excitation channels is selected to illuminate a specimen, the plate is moved within a single plane of motion.
Abstract: Illumination system for a microscope system capable of being mode-switchable between a first and a second illumination mode, comprising one source of light for providing a collimated beam of light, at least one selector mirror capable of being positioned in at least two positions to redirect the beam of light in two different beam paths, the first beam path being a direct exit beam path wherein the selector mirror redirects the beam of light along an exit beam path to provide a first illumination mode, the second beam path is a mirror loop path comprising two or more mirrors arranged to redirect the beam of light onto the selector mirror such that it is redirected by the selector mirror a second time along the exit beam path, and wherein mirror loop path comprises at least one optical element arranged to optically alter the beam of light to provide the second illumination mode.
