FortéBio Personal Assay BLItz® System

FortéBio Personal Assay BLItz® System

Label-free assays in a drop

Simple and rapid

The BLItz System enables the detection of specific mAbs, even in unpurified samples, in as little as 30 seconds.

Save sample

Affinity, concentration and binding kinetics can be measured right at the bench in a 4 µL drop of sample.


Drop. Read. Done. 

The BLItz® system brings label-free analysis to individual researchers and is affordably priced so everyone can have one. With this personal assay system, you can run protein quantitation and kinetics experiments in only 4 µL of sample — right at your own lab bench.

Instant protein presence

Detect the presence or absence of active proteins in just a drop of sample and easily identify specific proteins in complex solutions. Data from the BLItz system complements existing methods like blots and gels, and its real-time binding curves give instant visual confirmation.

Faster protein quantitation

Measure protein concentration without labelling or secondary reagents — even in crude media. With a wide dynamic range and sensitivity down to a few ng/mL, the BLItz System gives you accurate quantitation in seconds compared to traditional methods that can often take hours.

Easy reagent QC testing

Rapidly identifying specific proteins with immunoassay-based techniques like ELISA or HPLC add many hours to the process and delay results. With the BLItz system, proteins and antibodies can be quantitated in a matter of seconds with high specificity and sensitivity, even in crude samples.

Effortless kinetics

Get rate and affinity constants for binding interactions (ka, kd, KD) in minutes using only 4 µL of sample. With both a small price and a small size, the BLItz system can be your own personal label-free kinetics system. Ready to go right out of the box, its simple workflows let you run assays right at your lab bench with ease.

Smarter assay development

Monitoring the effects of changing conditions on binding interactions in real-time, the BLItz system lets you develop better immunoassays in only a few minutes. Find the best antibody pairs, identify the best assay parameters, and even build and optimise an ELISA step by step.
