Abstract: The disclosure provides materials and methods for assessing the presence and level of polyanionic compounds in a sample that inhibit PCR reactions, including assays for the presence, and optionally the amount, of polyvinyl sulfonate, as well as materials and methods for the reduction or removal of such compounds from buffer solutions and from protein solutions using a variety of approaches, including titration-based techniques.

Abstract: The present invention provides an improved manufacturing method for the production of bispecific antibody products, which comprise at least two binding domains. The process comprises at least the method comprising a step of refolding the construct, wherein one or more of the domains comprise a disulfide bond, and wherein the construct is contacted with a refolding buffer to refold the construct to its native form, the buffer comprising (i) a redox and/or oxidizing agent having a concentration of at least 0.1 mM and (ii) a chaotropic agent having a concentration >1 M, and wherein the pH of the refolding buffer corresponds to +/?4.5 of the pI value of the first domain or +/?4.0 of the pI value of the entire construct.

Abstract: The present invention relates to chromatography ligands having improved caustic stability, e.g., ligands based on immunoglobulin-binding proteins such as, Staphylococcal protein A, as well as methods of making and using such ligands.

Abstract: The present invention relates to an asymmetric chromatography media suitable for separations applications, particularly as packed bed, fluidized bed or magnetized bed chromatography media. In certain embodiments, the asymmetric chromatography media comprises asymmetric particles, preferably beads, having at least two distinct, controlled pore size distributions. Preferably one of the distinct pore size distributions is in an internal region of the particle, and the other is in an external region or coating on the particle. These distinct pore size distributions can be modified with uniform or alternatively unique functional groups or mixtures of functional groups. The present invention allows for the control over pore size distribution within an asymmetric porous particle by providing a distinct internal region, preferably in the form of a bead, and a distinct external region, preferably in the form of a coating on the bead.
