Scientists Show Protein-Making Machinery Can Switch Gears With A Small Structural Change
For the past several years, Min Guo, an assistant professor at The Scripps Research Institute (TSRI), has focused on the intricate actions of an ancient family of catalytic enzymes that play a key role in translation, the process of producing proteins.

White Paper: Comparability Of The Cell-Freeze® (Charter Medical) Freezing Bag To The Cryocyte™ (Baxter) Bag For Cryogenic Storage Of Human Hematopoietic Progenitor Cells Successful cryopreservation of hematopoietic progenitor cells (HPC) is dependent upon a number of factors, including the biopreservation media, freezing rates, and storage using sterile, cryogenically durable storage bags. The Cell-Freeze® cryogenic storage containers are 510(k) cleared for storage, preservation and transfer of hematopoietic progenitor stem cells (HPC’s). By Charter Medical, Ltd.

Comparing The Automated Pipetting To Volumetric Glassware And Air Displacement Pipettes
Analytical sample preparation is used in many industries such as forensics, environmental chemistry, mining, beer and wine fermentation and many others. Concentrated samples are diluted and analyzed via High Performance Liquid Chromatography, Gas Chromatography, Atomic Absorption, and/or Inductively Coupled Plasma Spectroscopy to name a few. Traditionally these samples are prepared using volumetric glassware, syringes and/or pipettes.

Avoiding Drug Shortages With Microbial Detection
Over the past year, critical drug shortages used to treat a host of life-threatening illnesses have been making headlines. Microbial contamination has been cited as a major contributor to the shortage, yet the prevailing practices to ensure the safety of drugs have been slow to change. In most cases, quality assurance practices safeguarding the drug making environment continue to rely on periodic air and a culturing method from a prior century.

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

Mixed-mode chromatography resin is a top tier selection for the manipulation, purification and handling of molecules; providing an unmatched level of separation properties and resolution. The combination of cation exchange resin and metal affinity resin properties, allows multimodal chromatography to provide an access route for biomolecules to separate and the use of alternative chromatographic methods make these biomolecules seem homogenous.
Macro-Prep hydrophobic interaction chromatography (HIC) media are methacrylate-based, 50 µm beads used for protein, polypeptide, enzyme, and nucleic acid purification.
ÄKTA avant™ is a preparative chromatography system designed for fast and secure development of scalable methods and processes.
