Technical Reports

The current gold standard in monoclonal antibody purification for most researchers is affinity purification with Protein A or G followed by size exclusion chromatography (SEC). Although robust and highly effective, this workflow does have critical pain points and inefficiencies, leaving researchers to feel that they must oversee every step of their workflow, not leaving their chromatography system unattended for more than a few minutes.

High purity protein is a common requirement for biochemical and structural studies. A common approach is to recombinantly express an affinity-tagged version of the protein of interest. However, this is not always a viable option. Here we showcase how the NGC Chromatography System and prepacked chromatography columns can be utilized to develop purification workflows for untagged proteins.

Reference gene selection and validation are very important for gene expression studies that involve different samples or experimental conditions and therefore are absolutely necessary before any further exploration. See how PrimePCR Reference Gene Selection Panels and CFX Maestro Software provide an easy-to-use system with which to select appropriate reference genes.

When developing biologics or biotherapeutics, it is imperative that no contaminating or hazardous residual components from the organisms responsible for protein expression remain after purification. See how the NGC Chromatography System was challenged with microbes and efficiently sanitized, making it ideal for the small-scale production of biotherapeutics.

Multiplexing with Droplet Digital PCR (ddPCR) allows for improved sensitivity and precision, as well as increased low-level detection in limited sample types like liquid biopsies. Learn about amplitude and probe-mixing multiplexing and how our ddPCR Assays can help set you up for multiplexing success.

Our new hydrophobic anion exchange mixed-mode resin, Nuvia aPrime 4A, has been developed to overcome existing challenges in antibody purification. See how we purified an acidic and basic antibody through bind-elute and flow-through modes of purification, respectively, and helped to improve process productivity and economy.

See how you can efficiently reduce identification of optimal protein purification conditions from five days to just 18 hours. All you need is a DOE model and the Multivariable Scouting tool and automation abilities of the NGC Chromatography System.

See how you can use CHT XT Mixed-Mode Media to recover over 75% of your virus in a single purification step. All this while reducing contaminating proteins by over 90% and removing over 60% of dsDNA. Get simple, fast, and reproducible viral purification with CHT XT.

The formation of aggregates is a common but highly undesirable occurrence during monoclonal antibody purification. See how on-column aggregation is dependent on the type of resin used and how one particular high-resolution cation exchange resin allows for the lowest proportion of aggregate formation.

Comprehensive and effective gene expression studies evaluate both transcriptional and translational regulation. A streamlined protocol was developed for the parallel analysis of mRNA and protein levels using a single lysate produced from cultured cells.
