RACE - Rapid Amplification of cDNA Ends02:35

RACE - Rapid Amplification of cDNA Ends

5.9K
Rapid Amplification of cDNA Ends, or RACE, is one of the most effective methods to obtain a full-length cDNA from an mRNA sequence between a known internal region to the unknown sequence at the 5’ or 3’ end. The unknown region is cloned in the cDNA by a gene-specific primer that binds the known end, and a hybrid primer that attaches a predefined anchor sequence to the unknown end of the cDNA. The sequence in between is amplified by PCR with an anchor primer and a gene-specific...

Genomics

35.5K
Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Issues And Trends In Healthcare Delivery System

6.5K
The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...

    Area of Science:

    • Genomics and Bioinformatics
    • Laboratory Informatics
    • Scientific Data Management

    Background:

    • Experimental laboratory activities are increasingly complex, generating vast amounts of diverse data and requiring sophisticated computer-based workflows.
    • Effective quality control and efficient data handling necessitate a robust Laboratory Management Information System (LIMS).
    • A LIMS provides comprehensive oversight of laboratory operations, promoting adherence to good laboratory practices.

    Purpose of the Study:

    • To design and implement a specialized software platform, QTREDS, tailored for the needs of the CRS4 Sequencing and Genotyping Platform (CSGP).
    • To enhance quality control, traceability, and data management within a high-throughput sequencing and genotyping laboratory environment.
    • To provide a flexible and adaptable solution for managing complex laboratory workflows and resources.

    Main Methods:

    • Developed QTREDS using Ruby on Rails, incorporating four core functional blocks: sample handling, workflow generation, inventory management, and user management.
    • Implemented a wizard-based sample handler for comprehensive sample tracking and chain of custody.
    • Integrated a visual, JavaScript-based workflow generator for user-friendly custom workflow design.
    • Established an inventory management system with barcode integration and stock level monitoring.
    • Incorporated a robust user management system with role-based access control and privileges management.

    Main Results:

    • QTREDS successfully manages samples, tracks their entire lifecycle, and ensures a complete chain of custody.
    • Users can easily design customized experimental workflows through an intuitive visual interface.
    • Efficient management of reagents, consumables, and laboratory supplies prevents stock shortages.
    • QTREDS provides a secure environment with defined user roles and access permissions.
    • The system has been in successful use at the CSGP for over a year, demonstrating its efficacy.

    Conclusions:

    • QTREDS enhances laboratory efficiency by enabling quick identification and resolution of issues, thereby reducing process failures and costs.
    • The system's design specifically addresses the needs of the CSGP, with proven success in a real-world setting.
    • QTREDS's flexible architecture allows for adaptation to other 'omics' laboratories.
    • The software is freely available to academic users, promoting wider adoption and research advancement.
