In 1995, CTL’s founding scientists introduced image analysis-based ELISPOT counting (US Patent 6,410,252 B1), marking the beginning of ImmunoSpot® Analyzers.

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:
