Personal assay BLItz System

Label-free assays in a drop
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.
-
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.

Label-Free Analysis on BLItz System
Features
-
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 labeling 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 4µL 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 optimize an ELISA step by step.
