LE Magnet Plate (Low Elution Magnet Plate)

Alpaqua LE Magnet Plate

The LE Magnet Plate is used with 96-well PCR plates when elution volumes need be kept at a minimum to ensure the highest possible product concentration. This plate allows you to elute in as little as 8-10 µl. The LE Magnet Plate contains a unique plate docking structure and is designed for use with a variety of 96-well PCR plates.

Elute in as Little as 8µl

The LE Magnet Plate is designed for automated* pipetting of 96-well PCR plates when elution volumes need to be kept at a minimum to ensure the highest possible product concentration. This plate allows you to elute in as little as 8-10 µl. The LE Magnet Plate is an indispensable tool for every sequencing lab and is compatible with virtually all 96 well PCR plates (see below for note about plate warping).


Benefits
        • Maximize Product Concentration
          Use the LE Magnet Plate when your starting material is limited, but your workflow requires a minimum product concentration. Elute in just 8-10 µl and skip the SpeedVac step!

        • Minimize Reaction Volume
          Save on BigDye® and other costly reagents by scaling down the entire reaction volume. It's like running a 384 well-sized reaction in a 96 well plate.
How does it work?

The magnets used in the LE Magnet Plate have a smaller hole diameter than the 96R and 96S magnet plates. PCR wells don't sink as deeply into those magnets, causing the ring of beads to form lower in the well. This means that less elution volume is required (on the order of 8-10 µl) to fully cover the beads and elute the product.

Despite the smaller magnets, the full working volume of the plate can be utilized. Tests with a working solution of Ampure® XP (1 part water + 1.8 parts Ampure) have shown the following settle times:

100 ul:     4 minutes
 200 ul:     6-7 minutes
 300 ul:     <10 minutes

Important Considerations
1) For Precision Automated Liquid Handling, not for Manual Pipetting: The LE Magnet Plate is intended for use with automated liquid handling equipment, and use with manual pipettors is not recommended. In order to remove liquid without disturbing the ring of magnetic beads, every pipette tip must be positioned exactly in the center of a confined bead-free area at the bottom of each well. While using a manual single-channel pipettor is possible, using a manual 8- or 12-channel pipettor is not. The LE Magnet Plate performs best in conjunction with an advanced liquid handling instrument equipped with a multi-channel dispense head, such as the Beckman Biomek® or the Eppendorf epMotion® platform. As a general rule, if your robot can safely work with 384 well PCR plates, it will probably work well with the LE Magnet Plate.

2) Only Use Flat PCR Plates: It is very important to only use flat PCR plates with the LE Magnet Plate. As shown on the left-side of the figure above, all wells must touch the LE magnets so the ring of magnetic beads will form at the correct position in the wells. Do not use warped PCR plates because if the wells do not touch the LE magnets, the magnetic beads will cluster at the bottom and cause bead carry-over in those wells. See examples of popular PCR plates that we have tested internally to help you choose a PCR plate that is fully compatible with the LE Magnet Plate.

The LE Magnet Plate works with most 96-well PCR plates - full-, semi-, or non-skirted.  The LE is not for use with single PCR strips.  Below are some common plates that we had available for testing.   Many others will work as well, as long as they are not warped.  One example of a plate that was warped out of the box is the ABI MicroAmp® Fast 96-Well Reaction Plate, 0.1 mL (see picture below). This plate will not work with the LE Magnet Plate.
