Formulation Effects on Opalescence of a High-Concentration MAb

    Monoclonal antibodies (MAbs) are increasingly formulated at concentrations >100 mg/mL as a means to deliver a high dose in a low volume (1,2). Such high-concentration solutions are commonly opalescent (3,4), an undesirable characteristic of biopharmaceutical products for several reasons. Although it may be only aesthetic, opalescent products are not considered pharmaceutically “elegant.” Of more serious concern, opalescence may be a precursor to aggregation and indicate a propensity toward decreased product stability or quality. The term opalescent refers to…

Rapid and Scalable Microplate Development of a Two-Step Purification Process

    High-throughput screening and process development methods are becoming more widely used in the biopharmaceutical industry. Recent development of high-expression (high–target-titer) recombinant culture methods has enhanced the need to also develop more effective separation products, methods, and processes (1). Part of the solution would be chromatographic resins offering higher capacities and flow rates.       However, developing an optimized purification process that involves several chromatographic steps can consume significant time and samples. In addition, a purification process developed…

30th Anniversary of Smallpox Eradication

    May 2010 marked the 30th anniversary of the World Health Organization’s declaration that the world had won freedom from smallpox. An intensive two-year search had discovered no evidence of the disease since the last case on 26 October 1977. It was a historic moment — no disease had ever before been eradicated. Smallpox had terrorized humans for more than 3,500 years and in the 20th century alone had been responsible for 300 million deaths. The success of the…

Industrializing Stem Cell Production

Stem cells have potential as a readily available, consistent source of many differentiated cell types. This unique property can be leveraged both for therapeutic purposes and for facilitating and improving a number of drug discovery and development processes. Large-scale, “industrialized” production of human stem cells in tightly controlled conditions will be required to deliver the quantity and quality of cells needed to support clinical trials and drug discovery development activities (Figure 1). Achieving this level of production while meeting rigorous…

Increasing Biopharmaceutical Quality Through Packaging Partnerships

Containers and administration devices are integral to the safety and efficacy of biopharmaceutical therapies and must be key considerations for all new drugs coming on the market. By partnering with packaging manufacturers early in development, biopharmaceutical manufacturers can increase efficiencies in their production processes while gaining expert advice and counsel throughout a drug’s lifecycle. Such an alignment can also improve product quality, enhance regulatory compliance, and contribute to the overall state of control by preserving biopharmaceutical stability, ensuring sterilization, and…

How to Choose an Industrial Cation Exchanger for IgG Purification

    Cation-exchange chromatography is the third most used industrial method for antibody purification after anion-exchange and protein A affinity chromatography. It is most commonly used as an intermediate step but continues to attract attention as a capture method. This offers obvious cost and cleaning advantages over protein A but also imposes some sacrifices, all of which are discussed in a number of recent articles (1,2,3,4,5). Whichever application may be intended, end users seek a common set of performance characteristics.…

Minimizing the Environmental Footprint of Bioprocesses

    Part 1 of this two-part article introduced the need to reduce the environmental footprint of bioprocesses and evaluated the impact of solid-waste disposal. Part 2 continues by describing the effects of the remaining elements of the bioprocess footprint: wastewater, electricity, and air emissions.   Wastewater   Process Waste Streams: Generally, raw materials to produce and purify biopharmaceuticals fall into one of the following categories: inorganic/organic salts, sugars/polyols, trace elements, vitamins, amino acids, surface active agents, or complex (undefined)…
