96-well plate

What are 96-Well Plate Viral DNA/RNA Co-Extraction Kits?

96-well plate viral DNA/RNA co-extraction kits purify both viral DNA and RNA from up to 96 cell-free samples simultaneously - plasma, serum, urine, nasopharyngeal swabs, saliva, CSF, and cell culture media -- using the same single-buffer lysis chemistry as spin-column viral kits but operating in a Zymo-Spin I-96 spin plate processed with a 96-well plate centrifuge or vacuum manifold. Both analytes co-elute per well in DNase/RNase-free water covering RNA viruses (SARS-CoV-2, influenza, HIV) and DNA viruses (adenovirus, HPV, parvovirus) without requiring robotic automation. The format provides a significant throughput step-up from single-tube spin columns - processing 96 samples in under 30 minutes with a multichannel pipette and standard centrifuge. Choose the 96-well plate format when daily viral sample volumes exceed 24 per run, when automation infrastructure is unavailable, or when batch surveillance testing requires rapid plate-scale turnaround from clinical specimens.

How to Choose a 96-Well Plate Viral DNA/RNA Co-Extraction Kit

Centrifuge vs. Vacuum Manifold Operation

A 96-well plate centrifuge rotor (accommodating the Zymo-Spin I-96 Plate dimensions) is the standard equipment requirement. If a compatible plate centrifuge is unavailable, a vacuum manifold that fits 96-well spin plates provides equivalent performance and eliminates centrifuge dependency. Confirm equipment compatibility before kit purchase.

Manual vs. Semi-Automated Pipetting

The 96-well format is designed for manual operation with multichannel pipettes for buffer addition and sample loading. Semi-automation is achievable with a liquid handler for buffer dispensing steps, leaving centrifugation as the manual step. For full automation without centrifugation, use the Quick-DNA/RNA Viral MagBead format on a compatible robot.

Lysis Buffer Volume Per Well

The single-buffer lysis system adds 200 ul of lysis buffer per well of sample (1:1 v/v for 200 ul input). Ensure the plate's well volume accommodates the combined lysis buffer + sample volume (400 ul total per well) plus ethanol addition before loading. Most Zymo-Spin I-96 plate protocols include a deep-well collection plate for this mixing step.

Positive and Negative Control Layout

Reserve wells 11 and 12 of each row for extraction controls. Fixed control placement across all plates enables automated data review scripts to flag failed wells based on consistent control positions.

Throughput Scaling Beyond 96

For programs processing 192-384 samples per day, run two 96-well plates sequentially on the same centrifuge or vacuum manifold. For volumes above 384 per day, transition to the magnetic bead format on a liquid handler (KingFisher, Tecan) to process 96 samples per automated run without per-batch manual centrifugation steps.

Specifications Context

The Quick-DNA/RNA Viral 96 Kit employs a single buffer system that facilitates viral particle lysis and DNA/RNA adsorption onto the Zymo-Spin I-96 Plate matrix, with validated recovery of enteroviruses, rhinoviruses, coronaviruses, HIV, HCV, influenza A, flaviviruses, measles, parainfluenza, and parvovirus. Nucleic acids are eluted in DNase/RNase-free water suitable for RT-PCR, NGS, and hybridization applications. 96-well plate viral extraction is the standard format in public health and reference laboratory surveillance programs, processing 96-384 clinical specimens per day, including respiratory multiplex panels, arboviral surveillance, and bloodborne pathogen screening, with throughput requirements driving adoption of this format over single-tube spin columns.
