Aptamer based point-of-care diagnosis and RNA therapeutics

Research and Development (R&D) start-up company seeking for new state-of-art technologies upon utilising RNA aptamers

Technology

Fluorogenic RNA Aptamer

Media1.avi

Fluorogenic Mango RNA aptamer is a specialized RNA segment, and the tertiary structure of Mango RNA specifically binds to a fluorogenic ligand, TO1-Biotin. 

The fluorescence signal of the ligand is exponentially enhanced only upon Mango RNA binding, and this feature has a strong advantage for single molecule RNA imaging

MANGO-NASBA Kit

MANGO-NASBA kit has been developed to meet the urgent needs of a rapid and accurate point-of-care diagnosis during the COVID-19 pandemic.

The theoretical limit of detection (LOD) is ~1 RNA molecule/µL, approaching the detection limit of RT-PCR, but is much faster and cheaper.

Our technology is potentially applied for any target RNA detection in patient samples (Saliva, Blood plasma, and cultured cells):

Pathogen / RNA-related diseases (including cancer)

Features :

No RNA isolation, Rapid, One-pot reaction, Isothermal reaction, and High compatibility with buffer (e.g., guanidin-containing viral transport buffer) 

Comparison of available detection methods

Detection Device

FRAM

A portable MANGO fluorescence detector, monitoring the MANGO signals over time at a defined temperature. 


Bluetooth-anabled device (Wireless detection available coming near future)

Lateral Flow Strip Assay

MANGO-Aptamer based pathogen detections

Now MANGO-NASBA amplified signlas are detected on the test line of lateral flow strip.

Mycoplasma Detection

We offer a LFA-based sensitive mycoplasma detection kit (coming soon)
