OPUS™ Prepacked Chromatography Columns with CaptivA™ PriMab™ Protein A Resin Speed Time-to-Market

Repligen™ OPUS (open Platform User Specified) prepacked columns packed with CaptivA™ PriMab™ Protein A resin offer high performance and all the advantages of single-use technology (reduced validation effort, reduced risk, faster time-to market). What makes this solution truly unique, however, is that oPUS prepacked columns provide lower total cost of ownership in many applications compared with conventional stainless steel or glass columns. Single-Use Chromatography Study BioPharm Services ltd (Chesham, UK) conducted a study to assess the impact on total cost…

EcoPrime

LEWA developed its first pulseless pump for liquid chromatography in the late 1970s and delivered its first chromatography system in the early 1980s. LEWA is the leader in supplying pumps used for pilot and industrial HPlC, SMB, and lPlC chromatography worldwide. A customer came to us several years ago requesting a lowpressure liquid chromatography system with a flow range of 20 − 2,200 L/h. They also wanted the ability to achieve linear gradient from 1 to 99%. We designed and…

Intelligent Tools to Facilitate Bioprocess Development

Continously new bioprocesses are evolving, and bioprocessors are searching for the easiest way to process samples in R&D. Currently, a huge trend towards disposable production systems is notable. For these purposes plastic bags, stirred-tank reactors, and storage tanks established on the market. Unfortunately, these reactor types are not suitable to perform sophisticated bioprocess development. In bioprocess R&D, throughputs of 50 to 1,000 fermentations are needed. Therefore, m2p-labs developed intelligent new tools at microscale to fulfill the needs in bioprocess development.…

An Update on the Advantages of Fibra-Cel® Disks for Cell Culture

          With a renewed acceptance of perfusion processesin cell in culture, both in the laboratory and for production applications (1), New Brunswick packed-bed bioreactors using Fibra-Cel® disks are seeing an upsurge in interest. This article examines Fibra-Cel technology and its many advantages, from increased yields of secreted proteins to labor savings in applications ranging from rabies vaccine production to production of the first licensed gene therapy drug.   What Is Fibra-Cel?   Fibra-Cel from New Brunswick…

Optical Oxygen and pH Sensors for Monitoring Biofermentation Processes

          Advances in sensor materials and optoelectronics have enabled new optical sensors for use in biotechnology, food and beverage processing, and more. These fiber optic chemical sensors work by trapping an oxygen-sensitive fluorophore or pH indicator dye in a sol-gel host matrix that is applied to an adhesive patch, the tip of a fiber, or a flat substrate such as a cuvette. The indicator materials change optical properties in response to analytes in their environment, and…

ActiCHO Media System

    Fed-batch protein production processes have become more favored because of their simplicity under large-scale conditions. PAA laboratories′ ActiCHO media system is an industrial media package for the cultivation of Chinese Hamster Ovary (CHO) cells in large-scale applications. It contains all media needed from cell thaw until harvest in large scale, which are a stock culture and cell-expansion medium, a production medium, and two appropriate feed media. The formulation of each single medium is titrated carefully to complement the…

Chromatographic Purification in Downstream Processing

          In many biopharmaceutical companies, chromatographic purification in downstream processing is a key focus for optimization studies. The objective is to streamline the process, which may be achieved by the elimination of intermediate unit operations. The main question, therefore, is how to optimize the adjustment of individual chromatographic process steps. Currently there is a broad range of next-generation sorbents and membranes available for process chromatography. These new chromatography media are characterized by significantly improved performance compared…

Increased Load of DNA-Based Oligonucleotide on TSKgel SuperQ-5PW (20) Resin

Oligonucleotides are entering clinical trials in increasing numbers. In many ways, their entry into the clinic mirrors the development of protein therapeutics in the late 1980s and early 1990s. On the other hand, the purification process for an oligonucleotide therapeutic is very different from that for a protein. Typically one high-resolution, high-load step is used rather than a train of capture, intermediate purification, and polishing columns. TSKgel SuperQ-5PW (20) resin — a 20-µm particle size anion-exchange medium — is becoming…
