Speedy One-Step ELISA Kits
The Speedy Kit is Proteintech’s one-step ELISA solution for rapid analyte detection. They are made with antibody pairs containing capture antibodies with Proteintech’s FcZero backbone. These antibodies have been engineered to silence the Fc-receptor binding site, thus eliminating non-specific binding with Fc receptors sometimes present in serum and plasma samples.

Speedy One-Step ELISA Kit structure
Rapid, Single-Wash Step Workflow
Speedy Kits enable analyte detection in 90 minutes or less. That’s nearly 3x faster than a traditional ELISA! Simply add all prepared samples, standards, and antibodies in a single incubation step, wash, develop, and read.
Unparalleled Sensitivity
Despite their reduced assay time and complexity, Speedy kits have not been compromised in their quality and deliver more sensitive results than similar offerings from leading competitors.
