A novel sandwich electrochemical immunoassay was developed for ultrasensitive detection of avian leukosis virus subgroup J (ALVs-J) using graphene quantum dots (GQDs) and apoferritin-encapsulated Cu (Cu-apoferritin) nanoparticles for signal amplification. GQDs were used both for the conjugation of primary ALVs-J

Despite the great strides made in the field of single-particle cryogenic electron microscopy (cryo-EM) in microscope design, direct electron detectors and new processing suites, the area of sample preparation is still far from ideal. Traditionally, sample preparation involves blotting, which

Theoretical considerations together with simulations of single-particle electron cryomicroscopy images of biological assemblies in ice demonstrate that atomic structures should be obtainable from images of a few thousand asymmetric units, provided the molecular weight of the whole assembly being studied

Questions

1–6 of 6 Questions  
  1. What is the density of A3660-1vl (Apoferritin from equine spleen)?

    1 answer
    1. The solution is 50% glycerol with 75mM NaCL, in addition to the presence of 50 mg of Apoferritin per vial. However, a 50% glycerol solution is typically expected to have a density of 1.26 g/ml.
