CloneSelect Imager ラベルフリー細胞増殖解析

細胞増殖の定量的評価と単クローン性の判定

CloneSelect™ Imagerは、白色透過光によるイメージングで細胞の増殖速度を客観的に定量し、コンフルエンシーを素早く測定します。マイクロプレートのウェル数に関係なく、プレート1枚の測定時間は90秒未満です。プレートにフタをしたまま測定できるので、測定後もインキュベーターに戻し培養を継続できます。細胞増殖は、すべてのプレートおよびウェルで観察され、追跡されるため、単クローン性の判定をサポートします。

FLUORESCENCE IMAGING PROVIDES GREATER CERTAINTY

The fluorescence imaging capability adds an additional level of confidence as researchers use an optional fluorescence viability stain to track their cells. The software can automatically perform cell count analysis on the fluorescence images, making it easy to identify wells that contain a single cell.

AUTOMATED, RAPID CONFLUENCE DETERMINATION OF CELLS GROWING IN MICROPLATES

  • Intelligent software analysis automatically calculates confluence for each imaging time point
  • Shown here is the confluence percentage of cells growing in each well of a 96-well microplate.

AUTOMATICALLY PLOTS TIME COURSE OF CELL GROWTH

  • Microplate images are acquired over time
  • Growth curve, image montage, total growth, and mean rate are generated automatically and are exportable

EASILY DOCUMENT MONOCLONALITY WITH A FEW CLICKS

With the ease of a few clicks, the Monoclonality Report feature organizes objective, quantitative, and qualitative data in an easily shareable report, enabling the presentation of image evidence needed to assure a high probability of clonality.

Example images from monoclonality report

  • Easily identify and select single-cell and artifact regions to include in report
  • Export high-resolution images of single cells, artifacts, and entire well (optional)
  • Automatically identify single cells with fluorescence version of CloneSelect Imager
  • Publish monoclonality report in PDF or Word Format

AUTOMATION COMPATIBLE

Cell Line Development Drug Discovery

PROOF OF CLONALITY

One of the regulatory requirements for biologics approval is to provide evidence that cell lines producing biotherapeutic proteins are derived from a single cell. The CloneSelect Imager can help in the following ways:
1. Save time and effort by reviewing wells that contain only a single colony with the intelligent “Loci of growth” function.
Instead of inspecting every single well in the plate, the “Loci of growth” function in the CloneSelect Imager software pinpoints wells that contain only 1 single colony, so users can save time and effort by only reviewing those wells.



2. Growth (image) history of each well can be tracked back to its starting point—providing evidence of monoclonality.

MONITOR COLONY OUTGROWTH

After screening and selecting colonies of interest, the CloneSelect Imager can monitor and evaluate subsequent colony outgrowth and productivity of the selected cell lines.

The CloneSelect Imager can also estimate the number of cells per well. Data is then exported to enable normalization of results from ELISA or cell-based assays against cell number.

COLONY FORMING ASSAY

Objective, Time-Saving Analysis
  • Every well can be imaged at any time point
  • Colony number and area quantified objectively
  • Focus on wells of interest, e.g. where growth is inhibited by test compounds

Review Results and Export Data
  • Dual gating for colony area and compactness
  • View each well at different time points
  • Export colony data



Save time by analyzing selected wells (highlighted in green).
Red wells are excluded.

ASSESSMENT OF CELL VIABILITY (MTT ASSAY)

CloneSelect Imager offers several benefits over traditional MTT assays for assessing cell viability in response to a cytotoxic challenge.
  • Replace time-consuming conventional techniques
  • Monitor cell death over time
  • Ensure a permanent record of data
  • Avoid costly reagents – no staining required

“THIS NEW IMAGE-BASED TECHNIQUE HAS THE POTENTIAL TO REPLACE THE CUMBERSOME MTT ASSAY WHEN FAST, UNBIASED AND HIGH-THROUGHPUT CYTOTOXICITY ASSAYS ARE REQUESTED.”
