Bio-Plex Pro SARS-CoV-2 Neutralization Antibody Assays provide reliably measure neutralizing antibodies in less than 3 hours. Watch our webinar to learn more.

Monoclonal antibody (mAb) purification methods often involve the use of resin-based chromatography. In this video, we compare a three-step mAb purification workflow, which uses Nuvia Ion Exchange Resins post–Protein A capture, to a two-step purification workflow, which includes a Protein A capture step followed by a mixed-mode chromatography step using Nuvia aPrime 4A Resin, a hydrophobic anion exchange resin. We present an additional two-step purification approach using Protein A resin followed by a calcium affinity cation exchange media, CHT Ceramic Hydroxyapatite XT Media. The results of both studies demonstrate that a high purity product can be attained using one fewer unit operation than traditional workflows.

The phosphoinositide 3-kinase/protein kinase B (PI3K-AKT) pathway is involved in the control of numerous critical cellular processes. PI3K-AKT pathway dysfunction has been observed in several diseases, including cancer, cardiovascular disease, and autoimmune and neurological disorders. In this animation, learn more about the molecular characteristics and function of the PI3K-AKT pathway and how AKT mutation plays a role in tumorigenesis.

Enveloped virus and VLP purification can be difficult. Learn about key factors and a cGMP-compatible, low cost, scalable process for retrovirus vector capture.

High-throughput screening (HTS) is a critical component of the entire drug discovery process. Flow cytometry is an attractive alternative to imaging and plate reader assays for HTS in drug discovery, due to its increased sensitivity and multiplexing capabilities. The ZE5 Cell Analyzer eliminates pain points that have hindered the full adoption of flow cytometry for drug discovery.

The SEQuoia RiboDepletion Kit employs novel technology to deplete ribosomal RNA while preserving rare transcripts and small RNAs, as well as minimizing the risk of degrading or low abundant samples. The SEQuoia RiboDepletion Kit also offers a streamlined workflow and multiplex compatibility, leading to significant time and cost savings compared to traditional methods.

The lack of reproducibility in research has been a source of frustration for scientists. Learn why antibody validation is critical for ensuring specificity and what validation methods Bio-Rad is implementing. Our scientists validate the performance of antibodies through CRISPR-Cas9 gene editing by knockout (KO), siRNA knockdown (KD), and immunoprecipitation followed by mass spectrometry (IP-MS).

Downstream process purification of proteins requires a resin with optimized bead size for ideal pressure/flow properties and decent dynamic binding capacity (DBC) that provides production efficiencies and good process economics. Nuvia IMAC Resin provides the mechanical strength, pore structures, ligand density, and particle size distribution required for an operational run at 300 cm/hr with a DBC of 40 mg/ml at 2 bar column backpressure. Protein purification can efficiently be scaled up from milligrams in the lab to kilograms in bioprocess manufacturing. The chemical stability of Nuvia IMAC Resins ensure efficient column regeneration, reproducibility between purification runs, extended column lifetime, and product purity. Watch our video to learn how Nuvia IMAC Resins overcome the challenges associated with process purification of proteins using metal affinity chromatography.

Purifying proteins that are not highly expressed can be challenging. Watch this video to learn about a case study demonstrating an efficient workflow for two-step purification of a low-expressing recombinant protein using mixed-mode chromatography.

Learn how a team developed a single-step workflow for column purification of the Influenza A H1N1 subtype using the recently developed Nuvia HP-Q Anion Exchange Resin. This protocol is scalable, efficient, and produced good yields with high purity.
