Fast ELISA Kits
Accelerate your research with ELISA kits optimised for speed, sensitivity and simplicity. Choose the ColorStep or QuickStep format — both need just 50 µL of sample and deliver quantitative results in under 120 minutes.
Two rapid workflows, both using 50 µL of sample and finishing in under two hours.
Distinct colour changes at each step make the protocol easy to follow and results more reliable. Available in 90- and 120-minute formats.
Results in 90 minutes with a simple single load-and-wash protocol — fast, efficient and reliable for streamlined workflows.
Each step produces a distinct plate colour, so you can see the assay progressing and catch a pipetting error before you read the plate.
Many ColorStep targets also run on a 3-step, 90-minute protocol with the HRP-streptavidin built into step 1, and every QuickStep kit returns results in 90 minutes. The protocol for your target is on its product page and in the kit manual.

ColorStep kits use colour-coded reagents that change colour at each step, making the sandwich protocol easy to follow (CV <6%). QuickStep kits prioritise speed with a single load-and-wash step in sandwich or competitive formats (CV <10%).
Both formats need only 50 µL of sample per well, and are validated for serum, plasma, cell-culture supernatant and other biological fluids. Check each product page for the exact validated sample types.
Human, mouse and rat, plus a broad set of other species including primate, rabbit, porcine, bovine and canine.
Yes. The 96-well format, short incubations and ready-to-use reagents suit high-throughput and time-sensitive projects, with lot-to-lot consistency for reproducible results.
