Abstract: A charged depth filter for removing cells and/or cellular debris from a biopharma feedstock having a first functionalized nonwoven layer having a first calculated pore size and a first dynamic charge capacity; a second functionalized nonwoven layer having a second calculated pore size and a second dynamic charge capacity positioned after the first functionalized nonwoven layer in the direction of the biopharma feedstock flow, and wherein the first calculated pore size is greater than the second calculated pore size, and the first dynamic charge capacity is less than the second dynamic charge capacity.

Abstract: Described herein is a method of purifying a target molecule from an aqueous biological composition, the method comprising: (a) contacting a cationic polymer and the aqueous biological composition to form a mixture, the mixture comprising a bio-polymer complex and the target non-binding molecule in a liquid, wherein the bio-polymer complex has an average particle diameter of at least 50 micrometers; (b) providing a filtering unit comprising (i) a housing having an inlet and an outlet, (ii) a porous, continuous filter medium which is fluidly connected to the inlet and the outlet, and (iii) a collection region upstream from the porous, continuous filter medium; (c) adding the mixture to the inlet; and (d) allowing the mixture to separate in the filtering unit, whereby the bio-polymer complex collects in the collection region and the target non-binding molecule passes through the filter medium, and wherein the majority of flow of the liquid through the porous, continuous filter medium is not substantially paralle

Abstract: Flow-through processes for purifying a target molecule (e.g., antibodies, enzymes, and hormones, particularly a monoclonal antibody) from a biological solution (e.g., a neutralized viral inactivation pool) in a sample that includes the target molecule, and devices for carrying out such processes.

Abstract: Described herein is method for testing an ion exchange chromatography device. The method includes monitoring both a binding and a non-binding species and determining their breakthrough point to determine a net breakthrough value. The method can be used to determine the integrity of the chromatography device, ensure that the chromatography device possesses the expected adsorbent capacity, and/or determine viral clearance of the chromatography device.

Abstract: This invention provides for a novel means of incorporating non-native amino acids into preselected positions of a protein using a cell-free synthesis system. The methods involve the use of non-orthogonal, native isoaccepting sense tRNAs that are encoded by the genetic code. Such methods allow for numerous non-native amino acids to be incorporated through the use of sense codons without having to rely upon orthogonal tRNA-synthetase pairs.

Abstract: Bacterial immunity proteins are utilized to increase immune response to an antigen of interest.

Abstract: Compositions and methods are provided for the in vitro synthesis of biological molecules in reaction mixtures comprising anti-foam agents. The reaction mix comprising antifoam agent may be a scaled up reaction, e.g. in reaction volume greater than at least about 15 ?l. Reactions may be performed in various reactors, as known in the art, which include stirred reactors, bubble-column reactors; and the like.
