Applications of CloneSelect Imager
-
Cell Line Development
Cell line development is a critical step in the process of generating biopharmaceutical molecules, such as monoclonal antibodies. The process often begins with transfecting the host cell type with the DNA encoding the therapeutic protein of interest allowing for random or directed integration of target DNA into the host cell genome. Thousands of clones are screened to isolate the rare high producing cells, a manual and time-consuming process.
Cell viability
Cell line development requires the discovery of single cell-derived clones that produce high and consistent levels of the target therapeutic protein. A critical first step in the process is the isolation of single, viable cells. Single cells proliferate to form colonies that can then be assessed for productivity of the target therapeutic protein. Viability and growth rates of single cell-derived clones can be characterized on the CloneSelect Imager and the SpectraMax i3x microplate reader and imaging cytometer.
-
Colony Forming Assay
The soft agar colony formation assay is a classical and renowned technique for characterizing the ability of cells to undergo anchorage-independent growth, a hallmark of carcinogenesis. After seeding in a matrix that enhances colony formation, such as a semi-solid media, cells are typically incubated with compounds that may affect colony growth. The CloneSelect Imager can image every well and automatically calculate confluence, estimate colony number and area, and track colony growth.
Label-Free Cell Migration
Wound healing assays are used in a range of disciplines to study cell migration, the coordinated movement of a cell population. A manual or standardized wound is generated on a monolayer of cells grown in microplates. The microplates can be screened against a library to study the effect on cell migration. The effect of a library of compounds or genes can be studied using this approach. The CloneSelect Imager enables the rapid imaging (<90 s per plate) and objective, automated analysis of cell migration.
-
Monoclonal Antibodies (mAbs)
Monoclonal antibodies (mAbs) originate from one unique parent cell, thus binding only to a single epitope. Monoclonal antibody discovery typically refers to the screening and identification of specific antibodies that target a specific epitope for the diagnosis and treatment of diseases, like the coronavirus for COVID-19.
Monoclonality
Cell line development and assurance of monoclonality are critical steps in the process of generating biopharmaceutical molecules, such as monoclonal antibodies. A cell line can be established following the isolation of a single viable cell robustly expressing the protein of interest. A key milestone in this process is documenting evidence of clonality. Documentation of clonality is typically image-based, whereby an image of a single cell is produced and included in regulatory filings.

Microscopy is then used to determine the number of cells seeded in each well and monitor cell growth. While monoclonality verification via white light imaging is possible, debris, dust, and air bubbles make it difficult and time consuming to identify single cells which may cause high value clones to be discarded. Here we present a fluorescent method for identifying monoclonal CHO-S cells using CellTracker Green CMDFA. We incubated CHO-S cells with Cell Tracker Green CMDFA and performed limited dilution to seed single CHO-S cells into 96-well plates. The CloneSelect Imager was used to image CHO-S cells in white light and fluorescence channels. By using fluorescence to identify cells, monoclonality verification is easier and more conclusive than using white light imaging or microscopy alone.
