As a leading international supplier of viral reagents, Advanced Biotechnologies has spent more than 35 years perfecting a process for creating large lots of the purest, most concentrated reagents available - from common strains to extremely rare products no other manufacturer can supply. Our products have reduced non-specific reactivity so if, for instance, you need to optimize an assay against a particular virus you can count on getting the native components of that virus, & nothing else. We manufacture on site in our own custom-designed facility, so we know exactly what goes into our products, & we carefully control every step of the process. We also perform QC testing after a freeze-thaw cycle, so you can be sure that we're analyzing exactly what you're getting. In addition to the diverse collection of products listed in our catalog, our skilled research team delivers outstanding results on custom projects & TEM services. We are committed to our clients success as we continually innovate our technologies, production techniques, & quality control measures.
