Speedy One-Step ELISA Kits
The Speedy Kit is Proteintech's one-step ELISA solution for rapid analyte detection. Made with antibody pairs containing capture antibodies with Proteintech's FcZero backbone, these antibodies have been engineered to silence the Fc-receptor binding site, eliminating non-specific binding with Fc receptors sometimes present in serum and plasma samples.
- Results in 90 minutes or less
- Reduced assay complexity with single-wash step protocols
- Unparalleled precision and sensitivity
- Unmatched cost savings
Rapid, Single-Wash Step Workflow
Speedy Kits enable analyte detection in 90 minutes or less — nearly 3x faster than a traditional ELISA. Simply add prepared samples, standards, and antibodies in a single incubation step, wash, develop, and read.
Unparalleled Sensitivity
Despite their reduced assay time and simplified workflow, Speedy Kits maintain excellent assay performance and deliver higher sensitivity than comparable kits from leading competitors.
