The world of biospecimen processing and biobanking is pivotal for the advancement of medical research. The Biospecimen Processing and Biorepository (BPB) shared resource at the Fred Hutchinson Cancer Center plays a crucial role by providing essential services that enable researchers to harness the power of biological samples. This article explores the key functions and contributions of the BPB, detailing its operations, services, and impact on scientific research.
Overview of the BPB Shared Resource
The BPB shared resource is staffed by a team of ten skilled professionals who specialize in the processing and storage of various biospecimens. Their expertise ensures that samples are handled with precision and care, adhering to standardized procedures that guarantee quality. The resource supports a wide array of studies by processing blood, urine, saliva, stool, and other biological materials, as well as isolating DNA and RNA from these samples.
The BPB also manages a comprehensive data entry system and maintains biorepository databases. This organization allows for efficient retrieval and shipment of samples, catering to both internal and external researchers. The resource is particularly valuable for large-scale, long-term population studies that require meticulous sample management.
Biospecimen Processing Services
The primary function of the BPB shared resource is to process biospecimens collected from various sources. Utilizing established standard operating procedures (SOPs), the team processes samples from blood, urine, and other biological sources. These SOPs are adaptable, which allows the team to accommodate the specific requirements of diverse research projects.
The processing service is not only systematic but also tailored to optimize the integrity and usability of each sample. This attention to detail is essential for ensuring that researchers receive high-quality specimens for their investigations.
DNA Extraction Techniques
DNA extraction is a cornerstone of the services provided by the BPB. The resource employs various salting out techniques to extract DNA from multiple sources, including whole blood, peripheral mononuclear cells, and formalin-fixed paraffin-embedded tissues. Each extraction method is tailored to the specific characteristics of the sample, maximizing yield and quality.
To assess the quantity and integrity of the extracted DNA, the BPB utilizes advanced instrumentation, such as Picogreen, Qubit, and Nanodrop. These tools enable precise measurements of DNA concentration and purity. Additionally, the Agilent TapeStation offers a further layer of quality assessment, ensuring that the DNA meets the rigorous standards demanded by researchers.
RNA Extraction Capabilities
In addition to DNA extraction, the BPB shared resource provides comprehensive RNA extraction services. The team is equipped to handle a wide range of starting materials, including tissues, blood, and FFPE samples. They employ rigorous methods to determine RNA quality and concentration, utilizing the A260/A280 ratio and TapeStation analysis.
The BPB also offers specialized microdissection services for FFPE samples, allowing for targeted extraction from specific areas of tissue. This capability enhances the precision of RNA studies, making it easier for researchers to draw meaningful conclusions from their analyses.
Biorepository Operations
The BPB is responsible for managing numerous biorepositories that contain valuable specimens for both internal and external investigators. These biorepositories house a diverse array of samples, including peripheral blood mononuclear cells, plasma, and serum. The centralized management of these resources enhances collaboration among researchers and streamlines access to essential biospecimens.
Among the significant biorepositories is the International Histocompatibility Work Group (IHWG) Cell and DNA Bank, established in 1999. This repository contains a wealth of reference materials that support research on human major histocompatibility complex (MHC) polymorphisms. Additionally, the Hematopoietic Cell Therapy Research Cell and DNA Bank (HCT-RCB) serves as a crucial resource for studies within the Hematopoietic Cell Transplantation Program.
Immortalization of B-Cell Lines
An innovative aspect of the BPB’s services is the immortalization of B-lymphoblastoid cells using Epstein-Barr virus. This process allows researchers to generate continuous cell lines for study without the interference of T-cell populations. The use of cyclosporine A in this process ensures successful proliferation while maintaining the integrity of the cell lines.
The BPB cryopreserves these cells for both short-term and long-term storage, ensuring that they are readily available for future research needs. This capability is vital for studies requiring extensive cell line libraries.
Biospecimen Ordering and Mycoplasma Testing
The BPB also facilitates biospecimen ordering and shipping services, adhering to the protocols of each study and biorepository. This streamlined process ensures that researchers receive their samples in a timely and efficient manner.
Moreover, the BPB offers mycoplasma testing services using high-throughput screening methods. This testing is essential for maintaining the integrity of cell cultures, as mycoplasma contamination can significantly affect experimental outcomes. The BPB is continuously exploring new testing methods to enhance the quality of its services.
Impact on Scientific Research
The contributions of the BPB shared resource extend beyond routine processing and storage. Its operations have enabled numerous high-impact publications and groundbreaking research endeavors. The meticulous care and expertise applied to biospecimen management have positioned the BPB as an invaluable asset within the scientific community.
