Visualize cells with
your microplate reader

Imaging with the SpectraMax MiniMax 300 Imaging Cytometer mirrors the plate reading workflow on the SpectraMax i3x System. The plate is set up for reading and images are acquired according to specified parameters. Cells in each image are identified by SoftMax® Pro Software and cell-by-cell statistics are collected. Data are then analyzed and visualized in different graphical representations.

 

Technical specification of the SpectraMax i3x are identical to those of the SpectraMax i3

With the SpectraMax i3x Multi-Mode Detection Platform, researchers are able to use a wide range of detection cartridges, like the ScanLater Western Blot System, that provide increased plate reader functionality. The SpectraMax MiniMax 300 Imaging Cytometer option is available for cellular imaging assays and the SpectraDrop™ Micro Volume Microplates for low volume DNA, RNA and protein sample prep. Now, all of your needs are covered with a single plate reader.

Scan Later Western Blot Detection System Western blot photo 150x.jpg

The ScanLater Western Blot Detection Cartridge is a user-installable option for the SpectraMax i3x and Paradigm® Multi-Mode Platforms. The ScanLater Western blot system simplifies the traditional western blot protocol by employing a europium-labelled secondary antibody which is then read by Time-Resolved Fluorescence (TRF). This substrate free detection method enables membrane scanning up to 30 days after the final wash step. The assay demonstrates sensitivity in the high femtogram, comparable to traditional chemiluminescence western blot methods. Leveraging this novel technology, researchers can:

  • Add western blot detection to their microplate reader within two minutes
  • Eliminate time-dependent substrate addition steps
  • Use one software platform, SoftMax® Pro Software to integrate both microplate and western blot detection assays

Features

  • User-installable cartridge for the SpectraMax i3x and Paradigm Multi-Mode Platforms
  • TRF detection using Europium-labelled secondary antibody reduces background while increasing dynamic range.
  • Digital photon counting provides TRF counts unaltered for a high level of data integrity
  • Europium resists photo bleaching and is stable for weeks, enabling re-use of blots
  • Compatible with goat anti-rabbit, anti-mouse or streptavidin labeled antibodies
  • SoftMax Pro acquisition and analysis software that provides built-in protocols for Western Blot reads and easy-to-use image analysis and accurate quantification tools
