Spear Bio is a biotechnology company developing ultrasensitive immunoassays for protein biomarker detection. Its core technology, Successive Proximity Extension Amplification Reaction (SPEAR), enables the detection of protein biomarkers at attomolar levels from sub-microliter sample volumes, claiming to offer two to three orders of magnitude higher sensitivity than current digital immunoassay platforms without requiring wash steps or expensive proprietary readers.

The SPEAR technology uses target-binding probes that bind to proximal sites in a protein's structure, allowing a unique "shake hands" mechanism that synthesizes a DNA sequence amplifiable by standard qPCR instruments. This approach provides extreme sensitivity and specificity, capable of detecting single-digit counts of protein molecules in sample volumes as small as 0.1 microliters. Spear Bio's assays are compatible with common qPCR devices, making them easily implementable and scalable in most laboratories.

In September 2022, Spear Bio launched its first commercial product, NAB-Sure, for ultrasensitive quantification of SARS-CoV-2 neutralizing antibodies from challenging samples such as finger-stick dried blood spots and nasal swabs. The company has expanded its NAB-Sure test kit offerings to include various Covid-19 variants, including Wild Type, Omicron BA.4/5, XBB.1.5, and BQ.1.1. These kits provide researchers with a highly sensitive, accurate, and precise cell-free alternative to traditional neutralizing antibody testing methods.

As of July 2024, Spear Bio was focused on developing ultrasensitive immunoassays for areas such as neurology, immunology, and oncology. The company aimed to leverage its technology's unprecedented sensitivity to transform protein research and early disease diagnosis, particularly in neurodegenerative diseases like Alzheimer's.

 

Key customers and partnerships

In July 2024, Spear Bio announced a strategic partnership with Bio-Techne Corporation, a global life sciences company. The collaboration aimed to advance research and diagnostics in challenging areas such as early diagnosis of neurodegenerative diseases.
