Enabling the Discovery of Novel Biomarkers, Diagnostics and Therapies
Human plasma, the liquid portion of blood that contains proteins, electrolytes, and other vital components, plays a crucial role in biomedical research. This complex biological fluid has been the foundation for numerous therapeutic and diagnostic advancements in medicine, contributing to a better understanding of various diseases and the development of life-saving treatments.
Plasma is typically obtained from volunteer donors through a process called plasmapheresis. Blood is drawn from the donor during this procedure and then separated into its individual components. The plasma is collected, while the remaining blood components are returned to the donor. Rigorous testing and screening procedures are followed to ensure the safety and quality of the collected plasma. Donors are carefully screened for any health conditions or infections, and the collected plasma is tested for pathogens and other contaminants.
"A valuable resource for scientists and researchers, providing insights into the molecular and cellular mechanisms underlying various diseases."
Human plasma is a valuable resource for scientists and researchers, as it can provide insights into the molecular and cellular mechanisms underlying various diseases. Analyzing plasma components, such as proteins and other biomolecules, can facilitate the identification of potential biomarkers and drug targets and the development of novel therapeutic approaches. Additionally, plasma is analyzed for diagnostic purposes, such as monitoring disease progression or determining treatment efficacy.
Some of the key applications of human plasma in biomedical research are:
Biomarker discovery and validation
Plasma is an ideal source for identifying and validating biomarkers, which are measurable indicators of biological states or conditions. Researchers analyse plasma to detect changes in protein or metabolite levels associated with diseases or other medical conditions.
Disease diagnosis and monitoring
Samples can be used to develop diagnostic tests for various diseases, including infectious diseases, autoimmune disorders, and cancer. Researchers can identify patterns indicative of a particular disease state by analysing specific biomolecules in plasma.
Drug development and pharmacokinetics
Plasma is often used to study the pharmacokinetics of drugs, which includes the absorption, distribution, metabolism, excretion and toxicology (ADMET) of a drug in the body. Researchers can analyse plasma samples to determine the concentrations of drugs and their metabolites, which helps in understanding drug efficacy, safety, and optimal dosing.
Therapeutic protein development
Plasma-derived proteins have been widely used in the development of therapeutics, such as clotting factors for treating haemophilia, immunoglobulins for immune deficiencies, and albumin for fluid replacement therapies. Plasma can also be used as a starting material for producing recombinant proteins using various biotechnological methods.
Proteomics and metabolomics studies
High-throughput techniques like mass spectrometry and nuclear magnetic resonance (NMR) spectroscopy enable the comprehensive analysis of plasma proteins and metabolites. These studies provide insights into the molecular mechanisms underlying diseases, which can lead to the development of novel therapeutics and diagnostic tools.
Plasma contains immunoglobulins (antibodies) that can provide valuable information about the immune response to infections, vaccines, or other immune challenges. Researchers can use plasma to study the adaptive immune response and assess the efficacy of vaccines or immunotherapies.
Transfusions are used to treat patients with clotting disorders, liver diseases, or severe infections. Biomedical research on plasma helps to improve transfusion safety and efficacy by identifying new plasma components that can enhance the therapeutic benefits or reduce adverse effects.
Regenerative medicine and tissue engineering
Plasma and its components, such as platelet-rich plasma (PRP), have been explored for their potential to promote tissue repair and regeneration. Research on plasma-derived factors and their role in wound healing, tissue regeneration, and cell proliferation has significant implications for regenerative medicine and tissue engineering.
Human plasma is a valuable and essential resource for biomedical research. Its complex composition and diversity of proteins and biomolecules make it a useful tool for investigating disease mechanisms and developing new treatments. However, ensuring the safety and quality of human plasma for research use requires rigorous donor screening and testing to minimize the risk of transmitting infectious agents. Ultimately, the use of human plasma in research has the potential to drive scientific discoveries and improve the lives of patients with various diseases.
When considering a new clinical biosamples provider, researchers should check factors such as sample quality, storage conditions, and the availability of associated clinical data and confirm that informed consent is a mandatory requirement from patients before acquiring their biosamples for research purposes. Additionally, researchers must adhere to strict ethical guidelines, follow relevant regulations, and respect patient privacy.
