Compositions comprising an isolated peptide, which may for example optionally comprise a sequence selected from the group consisting of FDYDWY (SEQ ID NO: 2), SFSQNKSVHSFDYDWYNVSDQADLKN (SEQ ID NO: 3) or CSFSQNKSVHSFDYDWYNVSDQADLKNC (SEQ ID NO: 1), or any cyclized version thereof, and methods of using same, including for treatment of or prevention of formation of microbial biofilms and against adhesion of a cell to a surface.

The present invention provides methods for cryopreserving a population of cells with improved cell viability. In some aspects, the method comprises contacting a population of cells with a peptoid polymer comprising one or more polar peptoid monomers, e.g., formulated in a cryoprotectant solution, and cooling the population of cells at a temperature of from 0° C. to about −20° C. for a time period of at least about 3 hours to produce a population of supercooled cells. The supercooling methods of the present invention provide excellent post-thaw cell survival and recovery. In certain embodiments, the population of cells is present in a tissue or an organ that is cryopreserved by performing the supercooling methods of the present invention.

There is provided a range of novel disulfide bond containing compounds. These disulfide bond containing compounds can be used in a variety of applications such as solid phase peptide synthesis, solid phase organic synthesis, formation of dendrimers, formation of macromolecules and formation cyclic peptides; and as a component of a delivery vehicle with a bioactive molecule.
