  • Publication number: 20160160237
    Abstract: Preparations and methods of producing a concentrated mitochondrial preparation using inverted phase centrifugation are disclosed. The methods include centrifuging a closed-bottom tube containing a heavy phase including a mitochondrial suspension in the portion of the tube proximal to the axis of rotation and a light phase in the portion of the tube distal to the axis of rotation. The centrifugation causes the suspension to form a concentrated mitochondrial layer at the interface between the heavy layer and the light layer, and the fluid at this interface is collected to produce the concentrated mitochondrial preparation. The concentrated mitochondrial preparation can be used for various applications, including in vitro fertilization applications.

  • Patent number: 7083777
    Abstract: A pharmaceutical composition consisting of identical repeating units, each unit having a charge motif composed of a positively charged free amino moiety and a negatively charged moiety, wherein the positively charged free amino moiety and the negatively charged moiety of each charge motif are separated by at least one neutral amino acid, and wherein the positively charged free amino moiety of one of the charge motifs is separated by a distance of at least 8 amino acids from the positively charged amino moiety of another charge motif, and a pharmaceutically acceptable carrier. Said pharmaceutical composition is useful for inducing IL-2, activating T cells to produce a T helper 1 cytokine profile, suppressing IgG antibody response to specific antigen, promoting allograft survival, reducing postoperative surgical adhesion formation, and/or protecting against abscess formation associated with surgery, trauma or diseases that predispose the host to abscess formation.
