San Diego-based Cyntellect, a provider of biotech research instruments, has raised $9 million in equity, debt, and rights funding, according to an SEC filing. The company told VentureWire that the funding added to its Series E round, in which the firm raised $16 million last year, from undisclosed investors. Cyntellect’s instruments are designed to analyze, purify, and grow cells for life sciences research, according to product overviews on its website. In March, the company said it would provide its microplate-based cytometry system to scientists from Harvard University and the Howard Hughes Medical Institute for stem cell research.
