Automated Digital Pcr For Absolute Quantification Of Gene Expression . The Unversity Of Ottawa Is Pleased To Invite Qualified Proponents To Submit A Proposal For The Provision Of One (1) Automated Digital Polymerase Chain Reaction (Dpcr) With All The Necessary Proponents And Software For Absolute Quantification Of Gene Expression.The University&Rsquo;S Research Program Will Use This Equipment For Absolute Quantification Of Gene Expression Across A Range Of Biological Samples. An Automated Digital Pcr System Facilitates The High-Throughput Precision Detection And Quantification Of Specific Nucleic Acid Sequences Within A Sample. A Dpcr Process Is Based On Combining Dna Samples With Primers, Probe Dyes And Pcr Reagents. Nucleic Acid Samples Are Separated Into Thousands Fixed Volume Partitions, Each Of Which Serves As An Independent Pcr Reactions. Target Sequences Undergo Amplification Following A Standard Pcr Principles And Are Identified Via Fluorescence Detection Of Non-Specific Flourophores Or Sequences Specific Probes. A Dpcr System Is A Workhorse Equipment In Many Molecular Biology Labs That Provides Absolute Quantification Of Of Target Dna Sequences Within A Sample For Applications That Include Mutation Detection, Gene Expression Analysis, Genome Edit Detection, Copy Number Variation Studies, Multiplex Mutation Screening, Viral Titer Measurement, Contamination Testing, And Research Into Infectious Diseases. We Request An Automated Digital Prc System To Be Housed In The Core Molecular Biology And Genomics Laboratory (Cmbgl) At The University Of Ottawa. This Equipment Will Accommodate The Experimental Needs Of More Than 36 Research Groups Across Several Faculties At The University (≫100 Users). We Require A High Level Of Automation And Ease Of Usage To Increase The Capacity Of The Facility For Various Experiments. Finally, This Equipment Will Be Managed By A Trained Technician That Will Ensure Accessibility To Hqp From Various Labs, Departments And Faculties Across Uottawa, As Well As Users External To The University.General Description:An Automated Digital Pcr System (Qty 1): An Automated Generator Partions Nucleic Acid Liquid Samples In Thousands Of Nanolitre-Sized Partitions Accurately And Quickly, And Removes The Need For Human Pipetting. Full Automation Simplifies The Dpcr Workflow, Minimizes Hands-On Input, And Eliminates User-To-User Variability During Partitioning. This Ensures The Most Consistent Results Within Biological And Technical Replicates, And Reduces User Errors That Could Lead To Equipment Damages And Experimenal Flaws. The Dpcr System Detects Discrete, Volumetrically Defined Dna-Contaning Partitions And Quantifies The Nucleic Acid Sequences Based On Positive/Negative Fluorescence Detection And Fluorescence Intensity Within Each Individual Partition. The The Number Of Partitions Exhibiting Positive Flourescence Is Directly Proportional To The Amount Of Dna Molecules Present In The Sample, Thus Providing An Absolute Count Of The Number Of Target Dna Sequence(S) In The Sample. Furthermore, Dpcr Systems May Also Determine The Flourescence Intensity Within Each Partition To Inform The Researcher Of Sequence Specificity Ensuring Greater Accuracy When Quantifying The Target Sequence.An Automated Dpcr System Enhances The Dpcr Workflow By Reducing Human Error During Pipetting And Partitioning, Which Is The Main Cause For Variation Between Samples In A Dpcr Workflow. Our Facility Consistently Reports High Usage Of A Primary Dpcr Setup And Organizes Equipment Specific Dpcr Information Seminars With High Attendance Rates, Emphasizing The Demand For This Equipment. As A Workhorse Equipement In The Cmbgl, We Expect A Long Life Span As Well As Reliability. The Output Of Using The Infrastructue Is High-Quality Scientific Results That Are To Be Published In Peer-Reviewed Journals And As Conference Abstracts.
