inverted CommasI can’t recommend FloCyte enough to people. I wish everyone who prepares flow samples – even if they don’t run them – would take FloCyte’s courses

 

 

Certification Exam Preparation Course

FloCyte offered the first preparation course for the new ICCS and ISAC certification examination!    Qualification to take this test will be the same as those to take the exam:   Applicants must have a Bachelors degree or equivalent and two years of cytometry work experience, or four years of cytometry work experience.

Syllabus of the course also follows the outline of topics covered on the exam in approximately the same proportion as the exam.   Order of the topics as they are presented may differ.
