enabling laboratories to perform ultrasensitive immunoassays on microsamples at scale

Single-digit protein detection in MICRO SAMPLES

Spear Bio‘s 2-factor authentication detection technology is licensed exclusively from Harvard University. It can detect and quantify as low as single digit counts proteins per samples. This exceptional level of sensitivity permits the detection and quantification of low abundance biomarkers at the earliest stages of a disease, which opens the door for precision diagnostics.

Ultrasensitive immunoassays for smaller sample analysis

Spear Bio’s technology can extract previously unseen levels of information from minimally invasive microsamples, leading to key insights that would be otherwise unattainable. The ultra-sensitivity enables researchers to easily work from micro-samples. Enabling smaller samples opens up new options for sample collection, and makes it easier to conduct more tests from the same samples.

Simple and efficient work-flow

Spear Bio’s technology is highly scalable and easy to use. The homogeneous assay can be implemented in most bioanalytical labs with minimal training. Unlike other technologies, it does not require expensive proprietary instrumentation. Instead, Spear Bio’s assay is readable on now ubiquitous qPCR instruments, enabling rapid ram-up and adoption at scale by bioanalytical labs.

NAB-Sure™

SARS-CoV-2 Neutralizing Antibody Test Kit

NAB-Sure™ SARS CoV-2 Kit simplifies testing from sample collection through result by using real-time PCR systems to produce qualitative and quantitative NAb (titer) measurements. It combines PRNT level accuracy with unparalleled sensitivity to assess small sample volumes including dried blood spot (DBS).

SPEAR Immunoassays

Single-Digit Protein Molecule Detection in Microsamples

Ultrasensitive immunoassays capable of analyzing smaller samples beyond the limits of current standards. Spear Bio’s 2-factor authentication assay dramatically increases sensitivity with outstanding signal-to-noise ratio (low background), enabling high sensitivity and ability to analyze small volumes. Spear’s homogeneous reagent-focused technology leverages customers’ existing installed qPCR instruments base and can detect down to single digit counts of molecules per sample.
