Introducing the world’s most practical ultra-sensitive signal amplifier.

No matter what immunoassay you run, there are plenty of options for signal amplification. But most involve investing in locked systems with expensive instruments.

With Exazym®, researchers can now achieve up to 100x signal amplification and a 50x lower limit of detection with their current immunoassay. It is so easy and inexpensive that it puts highly reliable immunoassay amplification within reach of every researcher on Earth. See for yourself and spread the word.
