Isolay is a major augmentation manufacturer in operation during the 2020s. It owns a facility in Lima, Peru where new augmentations are researched and developed.[1] Isolay distribute and market their products worldwide including countries such as the United States and China.

Isolay was the target of several "enforced contractual transfers" of their employees to work for competing biotech corporations. A number of Isolay employees were kidnapped from Lima by Belltower Associates and transferred to other countries with the help of the Red Arrow triad.[1] They were then forced to work for other augmentation manufacturers such as Tai Yong Medical.

In 2027, the CEO of Isolay is the target of an anti-augmentation terrorist attack. He is dragged from his car and beaten in Mumbai, India.[2] In addition, following the leaked footage of augmented super-soldiers, violent protests take place outside the doors of one of Isolay's facilities.[3]

Isolay was the first of the major manufacturers to declare bankruptcy, during the collapse of the augmentation industry, in the wake of the Aug Incident.
