CHANGING THE PARADIGM OF EARLY-STAGE DISEASE
DIAGNOSTICS AND MONITORING

Enabling the detection of trace biomarkers in microsamples at scale

Developing robust, ultrasensitive immunoassays for tiny sample volumes

Single-digit protein detection

ULTRASENSITIVITY

Spear Bio’s 2-factor authentication detection technology allows the quantification of low abundance biomarkers at the earliest stages of a disease with exceptional precision. It can detect as low as single-digit counts of proteins per sample.

MICRO SAMPLES

Spear Bio’s sub-µL requirements allow minimally invasive sample collection.  It makes it easier to conduct more tests from smaller samples and conduct research or screening on a broader scale, especially in asymptomatic subjects.

Ultrasensitive immunoassays
Simple and efficient work-flow

HIGHLY SCALABLE

Spear Bio has a simple wash-free workflow and is readable on any non-proprietary qPCR instruments. It can be easily automated on open liquid handling platforms. This allows to rapidly scale testing in existing labs for large cohorts of subjects.

ULTRASENSITIVITY

Low fg/ml limit of detection thanks to SPEAR’s 2-factor authentication and resulting low level of background.

MICRO SAMPLES

1uL or less sample size. Enables minimally invasive sampling.

DYNAMIC RANGE

6+ logs of dynamic range, ensuring robust quantitative results across the board.

OPEN qPCR READOUT

Read by any open qPCR Platform.
No need for proprietary Instruments.

HIGHLY AUTOMATABLE

Homogenous assay with wash-free workflow leverages existing lab setup and liquid handlers.

SARS-CoV-2 Neutralizing Antibody Test Kit

NAB-Sure™

SARS-CoV-2 Neutralizing Antibodies 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.
