DropArray Bead Plates

Reduce sample preparation, improve data quality and biosafety.

Wall-less plate technology for miniaturizing bead-based immunoassays enabling small sample volumes (2-5𝛍l), reducing bead clumping, and saving reagents and antibodies.

Miniaturization with the DropArray-Bead plates reduces sample volume and bead consumption by 5X and decreases assay costs by >60%. Laminar flow washing is efficient and limits bead aggregation.

DropArray Bead Plates

Innovative Plate Design

The DropArray 96-well plate consists of an array of hydrophilic spots surrounded by a hydrophobic surface, which functions as a virtual wall that separates each spot.

Conforms to SBS standards

The DropArray plates are available in 96- and 384-well format and conform to SBS standards.

What the DropArray Bead Plates deliver:
  • Sample savings
  • Reduced cost of running multiplex immunoassays
  • Ability to utilize existing workflows
  • Excellent retention of beads for accurate results

“the DA-Bead method for analysis was comparable to, if not superior to, the conventional method in terms of consistency/precision, accuracy, sensitivity and dynamic range.”

VS

Traditional Plate Technology

(A) Incubation method principle in traditional plate (left) and DA-Bead Plate (right). Beads are freely floating with shaking in traditional well at 75µl volume vs. beads are fixed in a 15 µl drop in DA-Bead Plate by a magnet below the well and shaken.
(B) Washing method principle in traditional plate (left) and DA-Bead Plate (right). Magnet array with traditional plate either super packs beads at the side of a traditional well or keep beads as a monolayer resulting in aspiration of beads and/or incomplete washing with the nozzle/pipet based dispenser. Conversely, DA-Bead Plate magnet configuration maintains beads as a monolayer (right) resulting in complete washing with gentle laminar flow and minimal residual wash buffer leftover.

DropArray™ Plates Work with Existing Workflows

Versteeg et al-2017-luminex

Use your established, standard protocols with DropArray plates. The overall workflow remains the same. Available in 96-well format, the plates are offered individually or in bulk to suit your assay needs. Because they are easy to use with standard robotics, therefore there’s no need for additional capital investment. DropArray™ plates are compatible with magnetic beads.

HOW DA-BEAD PLATES STACK UP

Sample volume 10µl* 50µl*
Bead volume 5µl* 25µl*
Ease of washing Comparable to MTP N/A
No. of wells per kit 480 96
Total reagent cost of one 96-well assay $300 $1500
*These values may vary based on type of bead-based immunoassay.
