✦ Synopsis

Abstract

Existing methods for detecting complete virus particles in the serum of patients with chronic HBV infection are either insensitive or indirect. A method is described in which Dane particle‐associated DNA is extracted from a small volume of serum and detected by molecular hybridization using ^32^P‐labeled cloned HBV‐DNA or HBV‐DNA extracted from the serum of an immunosuppressed patient, followed by autoradiography and densitometry. There was a positive correlation between the amount of HBV‐DNA detected using HBV particle‐derived and cloned HBV‐DNA probes. The amount of HBV‐DNA detected in serum samples showed a positive correlation with the HBV‐DNA polymerase. The method was more sensitive than the DNA polymerase and HBeAg assays in detecting complete virus particles. It may be useful in determining the level of infectivity in patients and in monitoring response to antiviral therapy.

## Abstract We have used a new hybridization assay for the detection of the genome of hepatitis delta virus (HDV) in serum using a strand‐specific RNA probe obtained by transcription of a recombinant riboprobe. This assay was tested on a panel of 30 sera from HBsAg carriers with hepatitis delta ant

The objective of this study was to evaluate microflow imaging (MFI) as a sensitive tool to detect and quantify subvisible particle formation during freeze-thawing of an IgG(2) monoclonal antibody (mAb). Solutions of the protein formulated in 20 mM of histidine buffer (pH 5.5) were subjected to three
