Methods and devices for using mucolytic agents including N-acetyl cysteine (NAC)

Devices and methods incorporate mucolytic agents into a point-of-care testing device. The sample is loaded, and then the sample travels until it encounters one or more lysis agents and/or mucolytic agents. The mucolytic agent is preferably pre-loaded onto the collection device. In a preferred embodiment, the mucolytic agent is localized between the sample application zone and the conjugate zone. In embodiments with a sample compressor, one or more mucolytic agents may be pre-loaded and dried on the sample compressor, the sample collector, in various locations on the test strip, or in the running buffer.

Immunoassay Methods Utilizing Trapping Conjugate

Methods are provided for determining the presence of a first ligand in a sample. In some embodiments depletion conjugates are used to deplete the ligands different from but related to the first ligands from the sample. In some embodiments, interim binding agents are used to enhance the test signal.

20210155906 · 2021-05-27 · ·

The present invention relates to a stock solution (RLP Stock Solution) of mammalian cell-endogenous retrovirus like particles (RLP), a method of preparing a RLP stock solution, a kit containing a RLP stock solution, and a method of quantifying the amount of RLP removed from a solution. An RLP stock solution will contain a high concentration of RLP and an extremely low amount of any therapeutic proteins of interest. In some instances, an RLP stock solution will contain a very low amount of natural mammalian host cell protein (HCP) and DNA. The method of preparing a RLP stock solution will consist of the production of RLP during fermentation or cell culturing and the subsequent purification of RLP from fermentation or cell culture solution. The kit will comprise at least two containers. One container comprised of RLP stock solution and one comprised of PCR primers or one or more antibodies. The method of quantifying RLP comprises the steps of adding RLP stock solution to an in-process solution containing a recombinant therapeutic of interest, processing the resulting solution through a bioprocess purification technique, and then quantifying the amount of RLP removed.
