ImmunoSpot® Analyzers

Wide range of analysis solutions for different needs
and budgets

In 1995, CTL’s founding scientists introduced image analysis-based ELISPOT counting (US Patent 6,410,252 B1), marking the beginning of ImmunoSpot® Analyzers. Since then, thousands of these instruments have been sold world-wide serving the "who's who" of academic and biotechnology researchers. Learn more about why ImmunoSpot® Analyzers have been so successful.

ImmunoSpot® Analyzers are not only the most successful ELISPOT/FluoroSpot analyzers on the market, they also are multifunctional, enabling other tests that are frequently performed in immune monitoring laboratories such as PBMC counting, cytotoxicity and serum neutralization assays, reading cytokine arrays, and more. ImmunoSpot® Analyzers are several instruments in one, for the price of one.

CTL offers a wide range of ImmunoSpot® Analyzers that are tailored to different needs and budgets. Please see our new model lines below. We are happy to help you select the model that suits you best. We also offer factory refurbished analyzers and analysis services.
