ImmunoSpot® Readers excel in high throughput bacterial colony counting, in any well format, from 384 to Petri dish and square agar slabs.

• Serum bactericidal assays (SBA) and
• Opsono-Phagocytotic assays (OPK) are commonly counted by ImmunoSpot® Readers

For a key reference utilizing an ImmunoSpot® Reader for bacterial colony counting see J. Immunol. Methods. 2004, 292: 187.

ImmunoSpot® Readers are also uniquely suited for high throughput yeast colony counting, in any well format, from 384 to Petri dish, as applies to:

• Humanized yeast models
• Proteomics (Y2H)
• Antibiotic testing
• Toxicology

For a key reference utilizing an ImmunoSpot® Reader for such applications see Cell Death & Disease, 2011, 2:188

High throughput is of essence for colony counting. In an optimized configuration, an ImmunoSpot® Reader can count a 384 well plate in less than one minute, with 400 plates in a single run.
