Provided herein are the use of polybrene as an additive in cell culture medium used in methods for the generation of high-titer hepatitis E virus stocks and assays for titration of hepatitis E virus. Also provided are a cell culture medium containing polybrene for high-titer HEV generation, a method for determining the presence and/or the level of HEV in a sample, and an HEV titration assay using polybrene.


Compositions and methods of the present invention prevent, inhibit or reduce the toxic effects of proteins and toxins secreted from microbes. A method for neutralizing microbial protein products in a subject comprises administering a composition to the subject, said composition comprising plasma-derived IgM and optionally one or more excipients in a pharmaceutical carrier, wherein the composition is administered in an amount effective to neutralize the microbial protein products.


Provided herein is a method of purification of non-enveloped or pseudo-enveloped virus produced in vitro using a composition with at least one detergent. Also provided are a method of purification can use multiple detergents, and a method of determining the presence and/or level of a non-enveloped or pseudo-enveloped virus in a sample.


Embodiments of the present invention provide methods for the treatment or prevention of infection-related immune conditions using compositions comprising IgM.


Method for correcting the position and deviation of a syringe needle in a machine for automatically preparing intravenous medication, the machine comprising an automatic actuator, together with a control system, in which are placed the syringe and a one-dimensional position sensor comprising a measuring plane, the correction method comprising the steps in which the position sensor obtains position coordinates of a first and a second point of the needle, and steps of correcting the position and deviation error of the needle, by the control system of the automatic actuator.


The invention relates to a device for determining a cellular-bound analyte in a liquid sample, comprising a separation matrix with at least one indicator zone. The invention is characterized in that the indicator zone comprises a first antibody directed against the cellular-bound analyte or a fragment thereof and a binding element directed against the first antibody, the first antibody being an incomplete antibody. The separation matrix is preferably designed in the form of the membrane of a lateral flow assay device or as a gel matrix. In a particularly preferable manner, the device comprises a membrane (2) with a charging zone (5) for applying the liquid sample, at least one indicator zone which can interact with the cellular-bound analyte, and at least one absorption region (3) which absorbs the liquid after passing the indicator zone. The indicator zone lies between the charging zone (5) and the absorption region (3). The invention is characterized in that the indicator zone comprises an antibody directed against the cellular-bound analyte or a fragment thereof and a binding element directed against the first antibody, the first antibody being an incomplete antibody.


Embodiments of the present invention provide methods for the treatment or prevention of infection-related immune conditions using compositions comprising IgM.
