There is described an apparatus for measuring protein characteristics comprising an X-ray fluorescence (XRF) spectrometer comprising a source of polychromatic X-rays, an X-ray detector, a protein, a molecule that has been exposed to and at least weakly binds to the protein, a plurality of X-ray fluorescence signal data obtained by irradiating chemical elements in the protein and molecule with the polychromatic X-rays and a security system for maintaining records for the data from the plurality of X-ray fluorescence signal measurements. There is also described an x-ray microscope for measuring a sample.

Human phermones may be used to alleviate anxiety, promote beneficial moods, and to alter hypothalamic functions, such as satiety, energy balance, and reproductive biology. The present invention provides methods for using Zlipo1 and glycodelin as pheromone polypeptides.
Human phermones may be used to alleviate anxiety, promote beneficial moods, and to alter hypothalamic functions, such as satiety, energy balance, and reproductive biology. The present invention provides a new group of human pheromone polypeptides, collectively designated “ZHMUP-1.”
In mammals, the vomeronasal organ, which detects phermones, resides in a blind-ended pouch within the septum of the nose. Vomeronasal organ-derived signals bypass higher cognitive centers and are processed directly in regions of the amygdala and hypothalamus, which have been implicated in the regulation of innate behavior, reproductive physiology, and other neuroendocrine responses. ZVNR4 encodes a human vomeronasal seven-transmembrane domain receptor.
