Secondary Antibodies

Proteintech offers a comprehensive portfolio of highly sensitive secondary antibodies which have been validated to detect unconjugated primary antibodies in various applications. Our secondary antibodies are offered unconjugated or conjugated to HRP, Alkaline phosphatase, Biotin, and a range of fluorescent dyes including our high performing CoraLite® fluorescent dyes.

Nano-Secondaries®

High resolution and low background

Nano-Secondaries® are the next level of secondary antibodies. They enable cleaner images with higher resolution. They consist of VHHs, also named Nanobodies, conjugated to Alexa Fluor® dyes. Nano-Secondaries have high affinities and bind to primary antibodies in a subclass and species-specific manner.
