10.28.20 -- Solve Viral Vector Vaccine Development Challenges

 
A Model System For Fast Screening Of Optimal Protein Purification Conditions
 

Identifying optimal purification conditions can be a time-consuming process that requires the evaluation of multiple parameters such as sample, resin, buffer system, pH, salt concentration, and flow rates. This study highlights a model system for screening optimal protein purification conditions on a mixed-mode cation exchange resin using a statistical software-generated design of experiment model.

Effective Downstream Purification For A Clinical-Stage Retrovirus-Like Particle
 

Purification of enveloped viruses and virus-like particles is challenging due to their size and complexity. This study demonstrates resin screening, process development, and scale-up purification of a retrovirus-like particle. This protocol is readily scalable, fast, low cost, simple, cGMP-compatible, and can be used for the capture step in clinical-grade manufacture of retrovirus vectors.

Viral Quantification: Adeno-Associated Virus Vector Genome Titer Assay
 

Recombinant adeno-associated virus (AAV) is rapidly becoming the vector of choice for human gene therapy applications due to the ability to achieve prolonged gene expression in a variety of tissues without a significant immune response or toxicity. Read about a highly precise method to determine AAV vector genome titers not unduly influenced by inefficient amplification or standard curve issues.
