Abstract: An apparatus configured to integrate with existing fire system strobe/horn plates. The apparatus may be a mass notification plate. Also disclosed are embodiments of a strobe housing configured to mix and/or reflect light emitted from one or more light emitters, such as high intensity LEDs, through a lens. The lens may be configured to produce a mass notification pattern. Further disclosed are embodiments of systems and methods that may be configured to deliver strobe control signals and/or strobe color control signals over a two-wire fire system powerline.

Abstract: A method for evaluating binding of a ligand to a target protein. The method includes the steps of: (a) providing a sample comprising a target protein and a ligand, wherein the target protein and ligand are suspected to be bound reversibly together in a complex; (b) preconditioning activated charcoal with the target protein; (c) contacting the sample with the preconditioned activated charcoal for a time sufficient to allow for adsorption of unbound ligand to the activated charcoal; (d) eluting the sample from the activated charcoal; and (e) determining an amount of ligand in the eluted sample to thereby evaluate binding of the ligand to the target protein. An apparatus useful in carrying out the method, and a method of making the same, are also disclosed.
