Filtration assay
WebUsing parallel experimental procedures, reagents and receptor systems, data are presented that demonstrate the scalability of radiometric receptor-ligand binding assays from a 96- to a 384-well format. The higher density of the 384-well filter plate allows for quantitative receptor-ligand binding assays in a robust, fast and reagent saving format. WebIntroduction to gene therapy viral vector purification. Adeno-associated virus (AAV) is the main vector for gene therapy. Scalable, cost-efficient, and robust filtration and chromatography-based processes are required for AAV purification. Key for a successful process are high overall yields and efficient removal of empty capsids and other ...

WebMembrane Filtration Method for Bioburden Testing . Membrane filtration is the method of choice for products containing antimicrobial substances. In this method, the sample is passed through a membrane filter with a 0.45 µm pore size. The membrane functions as a barrier and captures microorganisms larger than the membrane pore size. WebLateral flow filtration (Fig 2B) is the principle behind so-called ‘dipstick’ assays. In this type of diagnostic assay, the operator immerses part of the filter matrix in a blood sample. The matrix then separates the cells from the plasma as the sample travels through the material. This approach is well suited for diagnostic assays ...
WebDec 1, 2010 · We have developed a microplate-based detergent screening assay named the differential filtration assay (DFA) (Fig. 1). Differential filtration (DF), the simple underlying principle, is that the variation of amounts of macromolecules in filtrates obtained by parallel passages of a macromolecular solution through several different MWCO filters ... A filter binding assay measures affinities between two molecules (often protein and DNA) using a filter. The filter is constructed of nitrocellulose paper, which is negatively charged. Since most proteins have a net positive charge, nitrocellulose paper is ideal for immobilizing proteins. DNA is negatively charged due to the phosphate backbone and will not "stick" to the nitrocellulose on its own, however, any DNA that has been bound by protein will stick. The exact amount of DNA "st…
