  • The Challenge of Measuring Total Organic Carbon In Modern Pharmaceutical Water Systems

    Total Organic Carbon (TOC) is one of the quality attributes defined in the European and USA pharmacopoeias for pharmaceutical waters. Modern water treatment systems can deliver such high purity water that TOC levels can be consistently close to zero and very difficult to measure with any accuracy. This paper discusses some of the challenges when using TOC analysers to demonstrate pharmacopoeial TOC level compliance for modern water systems in the light of the ICH Q2 document from the International Conference on Harmonisation.

  • Agilent Microarray Grant Application Support White Paper This guide offers an overview of Agilent’s microarray and SureSelect product offerings with ordering details to assist researchers with the details of grant submission.
  • Continuous Harvesting Of Extra-Cellular Proteins From Mammalian Cell Cultures Utilizing Small-Scale Perfusion

    The use of a small-scale cell culture system not only maximizes the production of valuable protein but also avoids the high capital cost associated with system scale-up. Continuous harvesting can provide significant improvements in protein yields when compared to those of typical batch operations.

  • Rapid Screening Of A Cell-Based Assay For GLP-1 Receptor Using A Natural Product Library

    Here we demonstrate the detection of GLP-1R binding through the incorporation of a homogeneous cell-based binding assay using HTRF Tag-lite® technology. By Brad Larson and Peter Banks, BioTek Instruments, Inc. and Nicolas Pierre, Suzanne Graham, Jean-Luc Tardieu, and François Degorce, Cisbio US, Inc.

  • Guidelines For Proper Filtration And Delivery Of Samples To On-Line Process Analyzers

    Increasingly precise process control strategies, often linked to computer control, have accelerated the use of sophisticated on-line chemical composition analyzers in plant applications. Instruments such as gas and liquid chromatographs, ion chromatographs, laser optic instruments, atomic absorption instruments and specific ion analyzers, which were rarities in laboratories ten years ago, are now found routinely in plant settings. By Ken Perrotta, Division Engineering Manager

  • CD69 Expression On Activated Lymphocytes Is Stable In Streck's Cyto-Chex® BCT

    The purpose of this study was to determine if the activation marker, CD69, is preserved and stable in whole blood samples collected in Cyto-Chex® BCT. Previous studies have demonstrated CD marker stability of whole blood samples collected in Cyto-Chex BCT for up to 7 days when stored at room temperature (18-22°C).  By Jodi Alt, Ph.D

The QAII Station has been designed to ensure each tested dissolution apparatus conforms with mechanical specifications.

AseptiQuik® STC Connectors integrate the AseptiQuik® sterile connector and the Steam-Thru® II SIP connector, giving manufacturers even greater flexibility for hybrid stainless steel and single-use processing. 

The Avanti J-30I High-Performance Centrifuge System gives you the fastest separations possible - in the shortest amount of time. Swinging-bucket and fixed-angle rotors provide maximum separation forces in excess of 100,000 x g at speeds up to 30,000 rpm.

ÄKTA™ chromatography systems can handle both simple and complex purification tasks and accelerate daily routines. All systems are controlled by UNICORN™ software, a common control platform and user interface for all scales of operation. 

The Emphaze Hybrid Purifier is a new single-use clarifying device containing a multi-mechanism all synthetic Q-functional anion exchange media integrated with a fine particle, bioburden reduction membrane. The anion exchange media is comprised of a quaternary amine hydrogel supported by a fine fiber nonwoven scaffold. A combination of 3M technology platforms enables the hyperfunctionalization of a high purity polypropylene nonwoven with a covalently attached, thermally stable, water soluble polymer; the functional polymer accounts for roughly two-thirds of the mass of the anion exchange media. The bioburden reduction membrane is a highly asymmetric, high loading capacity polyamide membrane which has nine zones of decreasing pore size spanning a roughly 20X range and terminating with a 0.2 μm bioburden reduction rated pore size.

Amsphere™ A3 is a next generation Protein A chromatography resin for advanced protein separation in downstream processing of therapeutic antibodies manufacturing. With high capacity resin, Amsphere™ A3 has an overall improved process robustness, flow characteristics, optimized impurity removal, productivity and resin lifetime.

The Agilent 2100 Bioanalyzer is a microfluidics-based platform for sizing, quantification and quality control of DNA, RNA, proteins and cells on a single platform. Results are delivered within 30-40 minutes in automated, high quality digital data.

ÄKTA avant™ is a preparative chromatography system designed for fast and secure development of scalable methods and processes.
