The Top 30 Cell Culture Dish Blogs of 2016

I have compiled a list of our most popular 30 Blogs for 2016. Here are the top Cell Culture Dish blogs in alphabetical order.

A New Chemically-defined Medium for use with Suspension-adapted Avian Cells in Vaccine Manufacturing

Much of current cell-based vaccine manufacturing is done in cell lines like Vero (African green monkey kidney), MDCK (Madin-Darby canine kidney) or CEF (chicken embryo fibroblast) cells. These cell lines are adherent cells that require a surface to attach to in order to proliferate and produce viruses. Production scale-up with adherent cells is generally more challenging than with suspension cell cultures due to the surface area requirements for adherent cells…

Direct Inoculum of Bioreactors with CHO Cells from Frozen Seed Bags to Eliminate Continual Seed Trains and improve Facility Utilization

Flexibility in cell culture manufacturing via a reduction in process duration can be a key strategy for maximizing facility utilization and facilitating the production of multiple therapeutics from a facility. A key bottleneck is the seed train, which can add weeks to the timeline of the production culture. Seeding production bioreactors with a direct, cryopreserved CHO cell inoculum could possibly eliminate the need for a lengthy, continuous seed train and provide other numerous benefits…

Cool Tool – Pall AcroPrep™ Advance 96-well Long Tip Filter Plate Offers Efficiency and Flexibility in Nucleic Acid Purification

As the cell therapy industry increasingly moves from research to clinical trials and commercial manufacturing, it is necessary to scale up manufacturing processes to meet increasing product demand. Clinical and commercial manufacturing also requires that the manufacturing process be compatible with quality and regulatory expectations to ensure safety…

Affordable Biologic Downstream Purification with Single-Use Protein A Membrane

At this year’s Boston Biotech Week there were many exciting talks on downstream purification and associated new technologies. In particular, there were several talks about optimizing the downstream purification process. One very interesting talk, given by Renaud Jacquemart, PhD Principal Scientist, Director Vaccines Process Sciences, was titled “Enabling Manufacturing Of Affordable Biologics Through The Use Of A Protein A Membrane
 In A Single-Use Purification Strategy ” and focused on the application of a fully single-use chromatography purification process in place of resins. This strategy envisions the use of a unique Protein A membrane for which Natrix recently signed collaboration agreements with Merck & Co. and Sanofi…

The Top 10 Downstream Column Blogs in 2016

I have compiled a list of our most popular 10 Blogs for 2016. Here are the top Downstream Column blogs in alphabetical order…

Optimization of a Protein A Chromatography Process for a Herceptin® Biosimilar (Trastuzumab)

As part of our Boston Biotech Week 2016 coverage, we will be writing about some of the posters presented at the conference. One poster that caught my eye for downstream was presented by Oncobiologics and JSR Life Sciences, “Optimization of a Protein A Chromatography Process for a Herceptin® Biosimilar (Trastuzumab).” In the poster, Oncobiologics and JSR Life Sciences describe the steps taken in identifying the most efficient chromatography process…

Cool Tool – SCOUT® technology reduces time to market and increases chance of success for biopharmaceutical products

Only 1 out of each 50 biopharmaceutical new product candidates makes it through the research phase into clinical trial testing and subsequently to the market. This high attrition rate is predominantly in the early development phases and is attributed to (I) undesired pharmacokinetics profile (39%), (II) lack of efficacy (30%), (III) in vivo toxicity in preclinical model (11%), (IV) adverse effect in humans (10%), and (V) other reasons, of which most commonly commercial arguments based on cost of goods (10%). It is therefore imperative that technologies become available that allow significant de-risking of biopharmaceutical product trajectories in the early research and development phase. The importance of this has been recognized by the field with the introduction of the “Design of Experiments” (DoE) approach, identifying critical quality attributes and performance attributes like yield, glycosylation, potency, and consumable costs of a manufacturing process. Owing to the DoE approach, scientists now have a tool to strategize the development of a novel product candidate. That said, it is often found that due to the complexity of many novel molecules, the number of parameters that need to be tested still requires vast numbers of experiments which are time consuming and costly…

Cell Culture Events:

Bioprocess International West – February 27-March 2, 2017, San Francisco

The BPI West 2017 agenda format is designed to break down silos across multiple departments that work in the same stage of development. With four concurrent tracks focused on early stage process development through commercial manufacturing, attendees can collectively share challenges and discuss the solutions needed to improve the speed, cost and quality of biologics development.

World Vaccine Congress – April 10-12, 2017, Washington D.C.

The 17th Annual World Vaccine Congress is the place where the global vaccine industry meets to discuss commercial and scientific issues around regulation, strategy, manufacturing, trials, partnering, influenza, cancer, emerging diseases and veterinary vaccines.

Across 150 sessions, you will learn from leading experts across the issues most impacting on the wider vaccine sector, as well as delve into your specialist area of research and job focus in co-located conferences.

Meet over 700 of your peers in one room and take advantage of the multiple extended networking breaks, co-located World Vaccine Congress (including 7 streams on Immune Profiling, Cancer & Immunotherapy, Influenza & Respiratory, Clinical Trials, Emerging Diseases, Partnerships, Veterinary Vaccines and Bioprocessing & Manufacturing) as well as the evening drinks reception.

Case Study: CMC Biologics Explores the Potential of Continuous Multi-Column Chromatography – February 6, 2017

The Protein A capture chromatography step for monoclonal antibodies (mAbs) is both costly and challenging. Recent advances in continuous multi-column chromatography have drawn great interest due to the potential to dramatically lower the cost and complication of this key purification step in both semi- or fully continuous application. In this webinar, you will learn more about the practical application of continuous multi-column chromatography from the team at CMC Biologics and Pall Life Sciences.

Case Study: Merck Presents Scale Up of Continuous Chromatography using Cadence BioSMB Process System – February 20, 2017

In the present study, the development of a continuous Protein A chromatography process step using KANEKA KanCapA for the capture of a therapeutic mAb is described. The method was developed initially in a batch mode and then transferred to the Cadence BioSMB PD system. This five column process was then successfully scaled-up 150-fold using the Cadence BioSMB Process system. The entire process development and scale-up was completed within four weeks and described in detail along with the process economic benefits of using multi-column chromatography.
