[Establishing the species belonging of fragments and particles of striated muscle tissue by total IgG using quantitative solid-phase enzyme-linked immunosorbent assay].

Objective: Improving the way to establish the species belonging of muscle tissue fragments and particles using the quantitative solid-phase enzyme-linked immunosorbent assay method.

Material And Methods: We studied human muscle tissue fragments and particles (sampled 2-4 weeks before) and also dried extracts from the blood of certain animals, such as dogs, birds, pigs, and cats. The samples were studied using quantitative enzyme immunoassay with the domestic kit «IgG-total-ELISA-HEMA».

Hybrid Ultra-Low-Radioactive Material for Protecting Dark Matter Detector from Background Neutrons.

A laboratory technology for a new ultra-low background hybrid material (HM) which meets the requirements for neutron absorption with simultaneous neutron detection has been developed. The technology and hybrid material can be useful for future low background underground detectors designed to directly search for dark matter with liquid noble gases. The HM is based on a polymethylmethacrylate (PMMA) polymer matrix in which gadolinium nuclei are homogeneously distributed up to 1.
