This interview features: Jin Zhou, Co-Founder, Business Leader, Purilogics By Donaldson, from BioProcess International 2023.
High throughput purification of monoclonal recombinant antibodies using a Protein-A coated membrane plate system
Purilogics’ Jinxiang Zhou recently co-authored an article alongside Camila Leal-Lopes, Sara D’Angelo, Andre A.R. Teixeira, Andrew R.M Bradbury, Fortunato Ferrara, and M. Frank Erasmus – the Head of Bioinformatics at Specifica, Inc. We are excited to announce that this article has been published in the New Biotechnology Journal: High throughput purification of monoclonal recombinant antibodies using a Protein-A coated membrane plate system.
A Summary of Non-Viral Gene Therapy Approaches—Booknotes from a Review Paper
Gene therapy involves the manipulation of gene expression pathways in cells utilized in the treatment of both genetic and pathological diseases. The delivery of genetic-based material, such as RNA or DNA, to cells modifies their expression patterns.
A Vision of Future Gene Therapy: Non-Viral Nanovectors
Recent developments in research have highlighted the potential of non-viral nanoparticles as vectors in gene therapy. Gene therapy typically refers to the use of nucleic acids, such as plasmids and siRNA, to genetically modify patient’s cells.1 Traditionally, viral vectors have been pursued as gene delivery vehicles, but a variety of risks and problems associated with them have limited their large-scale use clinically.
What Do High-Throughput Purification Tools Mean to Upstream Antibody Scientists?
Recent developments have made small-scale antibody expression much easier. Upstream scientists can express tens or hundreds of antibodies in parallel. Analysis of purified samples at early stage will likely improve long-term success rate because there will be a reduction in interference of impurities.
Fundamentals of IVT Reactions and Our Purification Solution
In vitro-transcribed (IVT) mRNA is an alternative genetic material that can be used in the replacement of plasmid DNA in conventional uses…
Antibody Fragment Booknotes (1)
How can Purilogics help? We offer membrane columns for small-scale antibody purification. Our mini and midi columns can be used with a syringe to purify small volumes of antibody.
Addressing the Plasmid DNA Manufacturing Bottleneck
Over the past few years, we have seen a steady increase in the demand for plasmid DNA, as the gene and cell therapy industries have experienced rapid growth…
A Powerful Purification Platform Technology We Did Not Talk About: Hydrophobic Interaction Chromatography
Hydrophobic interaction chromatography (HIC) separates molecules based on differences in their hydrophobicity. It is an important technique in both sample analysis and preparative scale purification…
How Much Do You Know About mRNA Impurities?
mRNA impurities need to be removed to achieve high potency and safety throughout the production process. mRNA production begins with plasmid DNA, which then needs to be linearized.
What Differentiates Us from Other Membrane Chromatography Products
Purilogics offers a wide variety of differentiated products for your purification needs. Here are some highlights on the uniqueness of our membrane chromatography products:..
Simple Alternatives to Biologics Sample Purification via FPLC
Fast protein liquid chromatography (FPLC) is a common purification technique used widely in various biologics preparation. Often, we complain how slow chromatography columns are, but we have ignored that FPLC itself can cause more trouble than it is worth.
mRNA Size — An Important Factor You Cannot Ignore
Over the past 18 months, there has been a sharp rise in interest concerning the development of mRNA-based therapies, as highlighted by the FDA’s Emergency Use Authorization and subsequent approval of one of two novel SARS-CoV-2 mRNA vaccines.
Purexa™ Membranes Vs. Magnetic Beads — More Than Faster Speed
A key focus of Purilogics is to emphasize the drastic decrease in processing time when using our membranes for biologics purification…
Why is Membrane Chromatography Faster Than Resin Chromatography?
Imagine a glass holding sugar. After adding water, it is left to sit. Ultimately, the sugar will dissolve after a few hours…
How Does Flow Rate Affect the Binding Capacity of Purexa™ Membranes?
At Purilogics, we take pride in designing and developing membrane chromatography technologies for biologics purification. Our mission is to provide rapid and effective purification solutions to help the biopharmaceutical industry simplify biologics purification.
How to Purify mRNA – A strategy you need to consider
mRNA contains specific triplets of nucleobases (codons) that encode for different amino acids for the ribosome to follow and stitch together a peptide chain that will eventually (after some modification) become a functional protein…
Membrane chromatography – a faster alternative to resin chromatography
Antibody purification often involves the use of resin chromatogra¬phy columns for capture and polishing step purifications. However, pore diffusion of proteins is severely hindered in resins, resulting in low, flow rate-dependent capacity.
Fc-fusion Protein Purification Using Oversized Chromatography Columns? – A different purification strategy.
It is quite normal to see low titer recombinant protein feedstreams, such as Fc fusion protein, especially during early stage drug research and discovery. To obtain enough purified recombinant proteins, a large volume of feedstream is usually needed.
Antibody Purification – A superior alternative to magnetic beads.
Magnetic beads are generally effective to purify antibodies at small scale, but there are quite a few scenarios that they become a detriment to your workflow, such as:…
