In this article we will describe the procedure for measuring diffusion coefficients using multi-photon fluorescence recovery after photobleaching. We will begin by aligning the laser along the optical path to the sample and determining the proper experimental parameters, then continue generating and finally fitting fluorescence recovery curves.

Noroviruses are a major cause of gastroenteritis yet molecular techniques for their characterisation are still relatively new. Here we report two different reverse genetics approaches for the efficient recovery of murine norovirus (MNV), the only member of this genus which can be propagated in cell culture.

Muscle Recovery and Fatigue
0 Views •
2024
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective response...
FAQs
Maintaining suitable processing conditions protects the product's stability and biological activity, both of which can be compromised during downstream handling. This matters especially when the recovered material must retain its function, not merely be detected or separated. Careful condition control therefore links physical isolation with production of a usable biological product.
Clarification removes cells or other suspended material from a biological mixture, commonly through filtration or centrifugation. Selective purification then separates the desired product from remaining components using approaches such as precipitation, membrane separation, or chromatography. Distinguishing these roles helps organize the workflow, because removing bulk material and achieving product purity are related but different objectives.
Each recovery step can affect several outcomes at once. Efficient processing seeks to retain as much desired material as possible while removing unwanted components and preserving biological activity. The combined performance of harvesting, clarification, and purification therefore influences yield, purity, and consistency, rather than allowing any single operation to determine overall process quality.
A typical sequence begins by harvesting cells or collecting culture medium, followed by clarification with filtration or centrifugation. The clarified material then undergoes one or more selective purification operations, such as precipitation, membrane separation, or chromatography. Conditions are controlled throughout the sequence so the desired product remains stable and biologically active during isolation.
The starting material may be cells, culture media, or another complex biological mixture. Depending on the workflow, equipment and operations can include centrifugation systems, filtration devices, membrane-separation setups, precipitation steps, and chromatography systems. These components support different stages of handling, from removing bulk material to selectively isolating the desired biomolecule.
Product recovery supports workflows involving recombinant proteins, vaccines, enzymes, metabolites, and other biomolecules. It is relevant both to laboratory research and to scalable biopharmaceutical manufacturing. In these settings, the process helps convert biological production material into a preparation with improved purity, consistency, and retained activity, while also supporting practical process economics.
