Host cell contaminant testing is a critical quality control measure in biopharmaceutical manufacturing. During the production of biologic drugs, host cells such as bacteria or mammalian cells are used to produce therapeutic proteins. These cells can leave behind residual impurities that must be detected and removed.

Testing focuses on identifying host cell proteins, DNA, and other contaminants that could affect product safety or efficacy. Sensitive analytical methods are used to ensure that impurity levels remain within acceptable limits before products reach patients.

Effective host cell contaminant testing supports regulatory compliance and builds confidence in biologic therapies. It helps manufacturers verify that purification processes are working as intended and that final products meet strict quality standards.

As biologic drugs become more complex, robust testing strategies are increasingly important. Continuous improvement in analytical techniques enhances detection capabilities and reliability.

Host cell contaminant testing plays a vital role in protecting patient safety. By…

Sustainability (from the latin sustinere - hold up, hold upright; furnish with means of support; bear, undergo, endure), is the ability to continue over a long period of time.[1][2] In modern usage it generally refers to a state in which the environment, economy and society will continue to exist over a long period of time.[3] Many definitions emphasize the environmental dimension.[4][5] This can include addressing key environmental problems, including climate change and biodiversity loss. The idea of sustainability can guide decisions at the global, national, organizational, and individual levels.[6] A related concept is that of sustainable development, and the terms are often used to mean the same thing.[7] UNESCO distinguishes the two like this: "Sustainability is often thought of as a long-term goal (i.e. a more sustainable world), while sustainable development refers to the many processes and pathways to achieve it."[8]

Details around the economic dimension of sustainability are controversial.[9]…

Schizophrenia (/skɪtsəfrɛniə/ ⓘ) is a mental disorder[17][7] characterized variously by hallucinations (typically, hearing voices), delusions, disorganized thinking and behavior,[10] and flat or inappropriate affect.[7] Symptoms develop gradually and typically begin during young adulthood and are never resolved.[3][10] There is no objective diagnostic test; diagnosis is based on observed behavior, a psychiatric history that includes the person's reported experiences, and reports of others familiar with the person.[10] For a diagnosis of schizophrenia, the described symptoms need to have been present for at least six months (according to the DSM-5) or one month (according to the ICD-11).[10][18] Many people with schizophrenia have other mental disorders, especially mood, anxiety, and substance use disorders, as well as obsessive–compulsive disorder (OCD).[10]

About 0.3% to 0.7% of people are diagnosed with schizophrenia during their lifetime.[19] In 2017, there were an estimated 1.1 million new cases and in 2022 a total of 24 million cases globally.[2][20] Males…
