SeQuant® HILIC (hydrophilic interaction liquid chromatography) HPLC columns constitute a range of high-performance tools for separating polar hydrophilic compounds.
This page covers the use of Sepharose High Performance media for purification of proteins, peptides or oligonucleotides, when to use them, and with which systems.
For outstanding separations with excellent peak symmetry, our range of Purospher™ STAR HPLC and UHPLC columns are available with a variety of modifications to suit your selectivity needs.
Flash-Chromatography columns are available with ball joints or threaded standard taper joints and EZSafe™ connections and are useful for rapid, preparative separations. Large columns are also available with Ace-Thred connectors.
Attenuated viral vaccines are created through passage and harvesting from foreign cells or hosts. This technical article describes the manufacturing process of these viral vaccines.
The entire PCR workflow is vulnerable to factors which introduce variability. Many of the variable components are unavoidable, such as the source of the sample or the requirement for a reverse transcription step. Assay design is also highly variable and
Here we discuss purification options when working with Sepharose® High Performance and we present some examples of media screening, capture and purification.
Influenza vaccines are commonly made using egg-based and cell-based manufacturing strategies. Find step-by-step information on the manufacturing process for each method.
Solubility of common cell culture components in water and in a solution of 2-Hydroxylpropyl beta-cyclodextrin. Cyclodextrin is a non-toxic compound useful for its ability to solubilize fat soluble vitamins and hormones.
Paprika is a spice made from dried sweet peppers, and is used for flavor and color in many types of cuisine. Contamination with polynuclear aromatic hydrocarbons (PAHs) can occur when pepper plants are exposed to these pollutants in the environment
An optimized LC-MS/MS based workflow for low artifact tryptic digestion and peptide mapping of monoclonal antibody, adalimumab (Humira) using filter assisted sample preparation (FASP).
Pyrograf®-III vapor-grown carbon nanofibers are within the class of materials termed multi-walled carbon nanotubes (MWCNTs), and are produced by the floating catalyst method.
Calcium phosphate transfection is a common method for the introduction of DNA into eukaryotic cells. This protocol can be optimized for use with a wide variety of cell types.
SPME fibers with Carboxen®/Polydimethylsiloxane (CAR/PDMS) and Polydimethylsiloxane/ Divinylbenzene (PDMS/DVB) coatings are now available on a nitinol core (NIT) in a SS assembly for improved fiber performance.
The Plant/Fungi DNA Isolation Kit provides a rapid method for the isolation and purification of total DNA from a wide range of plant and fungi species.
