Protein Storage and Stability Analysis Using the Zetasizer Nano ZSP
| By Malvern Instruments
Spidroins are a unique family of large, structural proteins that make up the bulk of spider silk fibres. The mechanical strength and elasticity of spider silk fibres have led to their successful use in the regeneration of peripheral nerves in rats [1], with the same properties giving the potential for use in a wide range of other applications [2,3,4]. The production of these proteins on an industrial scale, however, has only become possible fairly recently.

Using Differential Scanning Calorimetry to Inform and Accelerate Process Development for Protein Therapeutics
| By Malvern Instruments
The production and purification of immunoglobulins of the gamma isotype, particularly human IgG1, for diagnostic or therapeutic applications is now fairly routine. In the past decade IgE-based therapeutics have also gained momentum (1-3). IgE is important for host defense against parasites and for protective inflammation. Yet, IgE-mediated signaling through its receptors is also a focal point of inflammatory allergic disease (4). The constant region of IgE, is a homodimer containing duplicate pairs of three unique Ig-fold domains (Cε2, Cε3, and Cε4), and is responsible for binding its two receptors, FcεRI and CD23, also known as FcεRII.

Evaluating Product Texture Using Oscillatory Testing on a Rotational Rheometer
| By Malvern Instruments
Formulating products to have both the correct functional and sensory attributes can be a difficult task. The latter in particular relies heavily on user feedback which can take considerable time and effort to attain. In addition it is not always easy to interpret such feedback in the context of material properties and hence rheological data.

An Introduction to DLS Microrheology
| By Malvern Instruments
Microrheology techniques involve tracking the motion of dispersed probe (or tracer) particles in a complex fluid, to extract local and bulk rheological properties of the matrix. Analogous to mechanical rheometry techniques, a stress is applied to the system by motion of the probe particle, and the deformation (or strain) is measured through changes in the probe particle position.

A Basic Guide to Particle Characterization
| By Malvern Instruments
The aim of this guide is to provide a basic grounding in the main particle characterization techniques currently in use within industry and academia. It assumes no prior knowledge of particle characterization theory or instrumentation and is ideal for those new to particle characterization, or those wishing to reinforce their knowledge in the field. The guide covers introductory basics, particle sizing theory and particle characterization instrumentation, as well as a quick reference guide to help you decide which techniques might be most appropriate for your particle characterization needs. It is not inclusive of all particle characterization techniques; more information can be found at www.malvern.com.

Autoinjectors From Planning to Launch
| By SHL Group
Injectable drug delivery devices such as pen injectors and autoinjectors show a significant growth potential in the future. This white paper focuses on the development process of an autoinjector project from planning to launch and best practices on how to prepare for and address potential challenges along the way.

NTA: Nanoparticle Toxicity
| By Malvern Instruments
At the same time as an increasing interest in, and rapid development of, a wide range of materials and products containing nanoscale structures and engineered nanoparticles, awareness has grown that the longer term potential toxic effects of such materials and their potential environmental impact are poorly understood. Existing methods have been assessed and new methods sought by which such materials could be analyzed on a routine basis during development and manufacture.

Orthogonal and Complementary Nanoparticle Characterization Techniques
| By Malvern Instruments
How can I trust my data? This is a common concern for many researchers using particle measurement instrumentation. Is the data affected in any way by the measurement technology, or alternatively by the user during sample preparation or by the analysis parameters employed? To answer this question we need to consider the use of independent and orthogonal measurement techniques in order to provide confidence and measurement validation.

The Benefits of Real-Time Analysis for Process Development
| By Malvern Instruments
While much effort is expended in optimizing commercially operating plant, getting the process 'right first time' can be far more efficient. Real-time analysis of process parameters provides substantial support during development, streamlining and accelerating the evolution of successful process designs. Taking on-line particle size analysis as an example, this paper considers the rationale for investing in real-time measurement for pilot scale work. Case studies illustrate the various ways in which on-line systems promote efficient process development, easing the transition into profitable manufacture.

Understanding Yield Stress Measurements
| By Malvern Instruments
Many complex fluids, such as network forming polymers, surfactant mesophases, emulsions etc do not flow until the applied stress exceeds a certain critical value, known as the yield stress. Materials exhibiting this behavior are said to be exhibiting yield flow behavior. The yield stress is therefore defined as the stress that must be applied to the sample before it starts to flow. Below the yield stress the sample will deform elastically (like stretching a spring), above the yield stress the sample will flow like a liquid.
