  • Patent number: 11740233
    Abstract: Disclosed herein are antibody-nanoparticle conjugates that include two or more nanoparticles (such as gold, palladium, platinum, silver, copper, nickel, cobalt, iridium, or an alloy of two or more thereof) directly linked to an antibody or fragment thereof through a metal-thiol bond. Methods of making the antibody-nanoparticle conjugates disclosed herein include reacting an arylphosphine-nanoparticle composite with a reduced antibody to produce an antibody-nanoparticle conjugate. Also disclosed herein are methods for detecting a target molecule in a sample that include using an antibody-nanoparticle conjugate (such as the antibody-nanoparticle conjugates described herein) and kits for detecting target molecules utilizing the methods disclosed herein.

  • Patent number: 10082508
    Abstract: The disclosure provides methods for automated characterization of circulating tumor cells (CTCs), for example using automated tissue strainers. In specific examples, such methods permit characterizing a prostate cancer sample by simultaneously or contemporaneously detecting ERG rearrangements and PTEN deletions in the same CTC. Also provided are kits that can be used with such methods.

  • Patent number: 9448231
    Abstract: Embodiments of a system, method, and kit for visualizing a nucleus are disclosed. A tissue sample is pretreated with a protease to permeabilize the nucleus, and then incubated with a nanoparticle/DNA-binding moiety conjugate. The DNA-binding moiety includes at least one DNA-binding molecule. The conjugate binds to DNA within the nucleus, and the nanoparticle is visualized, thereby visualizing the nucleus. Computer and image analysis techniques are used to evaluate nuclear features such as chromosomal distribution, ploidy, shape, size, texture features, and/or contextual features. The method may be used in combination with other multiplexed tests on the tissue sample, including fluorescence in situ hybridization. Kits for performing the method include a protease enzyme composition, a nanoparticle/DNA-binding moiety conjugate, and a reaction buffer.
