  • Patent number: 11821902
    Abstract: Peptide and/or protein quantitation methods, kits, and compositions, particularly useful for mass spectrometry, are provided herein based on a bathocuproine-based composition complex such as bathocuproinedisulfonic acid disodium salt hydrate complex. The methods are one-step rapid absorbance methods using small sample volumes. They produce a robust signal with high signal to background ratio and accurately quantitate even complex peptide mixtures with low variability and high sensitivity.
    Type: Grant
    Filed: July 23, 2020
    Date of Patent: November 21, 2023
    Assignee: Pierce Biotechnology, Inc.
    Inventors: Paul Jeffrey Haney, Christopher L. Etienne, Sijian Hou, Erum Raja, Ramesh Ganapathy
  • Publication number: 20210072170
    Abstract: Various methods and devices are provided for searching the optimum sample condition of a sample for cryogenic electron microscopy. Multiple samples with different sample conditions may be screened using a sample inspection device. The sample inspection device includes at least a chamber formed between a top electron transparent layer and a bottom electron transparent layer for holding the sample. Multiple pillars are arranged within the chamber. The sample inspection device includes a window covering at least one of the multiple pillars.
    Type: Application
