Spear Bio recognized by AACC as “Best Abstract in Metabolomics” Poster
WOBURN, Massachusetts., September 2, 2022 /PRNewswire/ — The developer of an ultrasensitive protein detection platform, Spear Bio (www.spear.bio), presented its innovative immunoassay technology at the recent American Association for Clinical Chemistry scientific meeting and clinical laboratory expo, celebrated in chicago.
At the AACC event, Spear Bio introduced its first product to market: the NAB-Sure™ SARS-CoV-2 Neutralizing Antibody (NAb) Test Kit. Based on proprietary SPEAR technology, the NAB-Sure™ SARS-CoV-2 assay is a powerful research tool in the fight against the coronavirus disease COVID-19. It serves a variety of applications, including COVID-19 serological surveillance, vaccine efficacy testing, and longitudinal antibody durability testing.
Ultrasensitive protein detection from small samples
The immunoassay test kit is capable of detecting ultrasensitive proteins for small sample sizes, such as dried blood spot (DBS) samples from a finger prick, which can be collected at home. The assay is in high agreement with the precision of plaque reduction neutralization testing (PRNT), without the safety concerns and lengthy workflows of a cell-based assay. The NAB-Sure™ SARS-CoV-2 Assay provides a critical boost for COVID-19 vaccine developers, clinical laboratories, and healthcare researchers.
SPEAR technology enhances testing of SARS-CoV-2 NAbs with support for ultrasensitive automated test compatibility for many sample types, including DBS, plasma, and serum, and excellent lab-to-lab consistency in measurement results, even when comparing different types of samples.
Award for Best Abstract in Metabolomics
Co-founder and CTO of Spear Bio, feng xuanY yu wangPh.D., Head of Application Development, were recognized as the winners of the 2022 AACC Division Award for Best Abstract in Metabolomics for their Technical Poster B-087: “A New SARS CoV Neutralizing Antibody Titer Measurement Assay.” 2, ultrasensitive, high throughput, and quantitative on dried blood spot samples.”
The poster session provided information on how Spear Bio’s proprietary SPEAR technology provides real-time polymerase chain reaction (PCR) qualitative and quantitative NAb titer measurements. The poster explored how a two-step polymerase extension can generate a PCR-detectable signal with little background noise. It is this high signal-to-noise ratio that allows for higher detection sensitivity compared to standard ELISA test methods. The poster further explored the ability of the SPEAR platform to test neutralizing antibodies for new variants of SARS-CoV-2.

Spear Bio’s validated SPEAR technology provides a secure path to COVID-19 healthcare solutions for researchers facing tight restrictions and limited sample sizes, such as government agencies or research companies working with microsample collection devices such as DBS.
